No viability? No rediscovery!
By Branden Holmes. Published on 27 April 2025.
Introduction
Given the rapidly declining state of the world’s biodiversity, any global rediscovery s.l. of a taxon is very important, not just for its conservation but for other reasons too (Diesmos et al. 2005; Ladle et al. 2011; Vilela et al. 2022). Yet reporting that one or two individuals of a taxon that is considered (possibly) extinct are in fact extant should not immediately overturn its assigned conservation status. Every genuine disappearance from the human record is caused by a population decline whose precise severity is unknown, while rediscovery itself does not abate threats, so until the population is shown to be viable it is not clear that the taxon has actually avoided a singular path to extinction. Such premature pronouncements of global rediscovery aren’t meaningful, may provide false hope, and artificially decrease the gap between the current extinction rate and rediscovery rate. The assumption that other individuals exist is epistemically dangerous.
The critical importance of biological viability
Intrinsic viability here refers to any inter-individual biological unit (species, subspecies, population, clade, etc.) that theoretically has the intrinsic potential to survive indefinitely into the future (in generational terms), not factoring in the extrinsic conditions it faces in the real world. A single individual of a sexually reproducing taxon clearly lacks such potential (unless parthenogenetic or a self-fertile hermaphrodite), and thus is no better chance to survive >0 number of generations into the future than a wholly extinct one because it is impossible for both to do so (despite one of them having an extant individual). There is clearly therefore not just a non-zero lower bound for the size of a population of a sexually reproducing taxon in order for it to be able to persist indefinitely, generation after generation, into the future. Other criteria must be met that collectively reach the necessary conditions for intrinsic viability (e.g. minimum population size, reproductive connectivity, genetic diversity). This necessary (but not sufficient) condition for the long-term persistence and indeed recovery of a taxon has not been lost on scientists, with rediscovery sometimes being explicitly or implicitly couched in terms of the population rather than individuals (e.g. Keith & Burgman 2004; Humphreys et al. 2019; Toledo et al. 2023). Yet at least 12 papers (representing 11 taxa) published in 2022 reported only a single individual (e.g. Sumanapala et al. 2022; Turner & Bradley 2022; Wood & Walsh 2022), and a further 12 papers (representing 13 taxa) reported collecting every individual they found for preservation/study (e.g. Huang et al. 2022; Jałoszyński 2022; Vilela et al. 2022). Meaning that for 24 taxa there was no more than a single known extant individual at the time of publication (see Appendix). There is therefore no evidence presented that these taxa have been meaningfully rediscovered as they have not been shown to be intrinsically viable.
On the other hand, vegetative reproduction and self-compatibility in plants, and self-fertile hermaphrodism and parthenogenesis in animals, means that such taxa remain intrinsically viable even when down to a single individual. Yet despite this intrinsic viability, the practical risk that they or their offspring will die for any number of reasons before successfully reproducing is unacceptably high. Having genuinely declined because of one or more threatening processes (or stochastic events), these remain as extrinsic factors (when not abated, such as via ex situ conservation or by heavily managing the population) that will almost certainly prevent the theoretically minimum number of individuals required for intrinsic viability (this is the theoretical lower bound) from actually being viable over time in the real world. To this end, the concept of a Minimum Viable Population (MVP) has been very important (Nunney & Campbell 1993), which seeks to quantify the "needed" number of individuals such that the population will have an acceptably high chance of surviving a certain number of years in the future, and is therefore probabilistic in nature (this is the probabilistic lower bound). Unfortunately, precisely quantifying the MVP for a taxon is extremely difficult because it differs from taxon to taxon (Reed et al. 2003), and through time as each taxon’s genetic/demographic/connectivity/threat profile changes. While various models and assumptions have been/are/can be used to arrive at "the" MVP for a population, and it is important to acknowledge this diversity. But the general point here is that there is both a theoretical lower bound (i.e. intrinsic viability) and a probabilistic lower bound (i.e. the MVP), no matter how disputed the latter may be, and so we can simply bracket off the specific/disputed details.
Proto-viability
The probabilistic lower bound by its very nature cannot be lower than the theoretical lower bound, and given the nature of the myriad factors that negatively affect population size through time the probabilistic lower bound is invariably significantly higher than the theoretical lower bound. Conservationists in practice seek to conserve significantly more individuals than the theoretical lower bound as a buffer against extinction, and optimally will create further insurance populations if feasible. But the difficulties inherent with quantifying either lower bound presents an epistemic problem that affects the publication process and thus presents a practical problem. The demand to arrive at a full blown MVP value for a population (since the probabilistic lower bound is more important in practice), and then show that the population size actually meets that mark, would be extremely onerous on those seeking to publish peer-reviewed papers that report global rediscoveries. Regular publication of papers helps to disseminate knowledge and aid communication between researchers, which has benefits over fewer papers of a larger size, and helps to catalyse conservation actions/study into individual populations. Withholding these papers altogether would do active damage to the field of conservation biology. Therefore, the reporting of a global rediscovery should be reserved for cases where it has at least been shown that the taxon is comprised of a sizeable (sexually diverse, if applicable) population with active breeding and recruitment of young into the adult population, which we might term proto-viability. There are potentially many ways of defining what constitutes a "sizeable" population, but as long as it is sensible it will work well enough for the purpose. This then places less burden on those involved in the highly laudable exercise of trying to rediscovery viable populations of taxa thought to be (functionally) extinct, while still rightly holding them accountable to a satisfactory level by demanding that they meet a standard of evidence that a particular taxon has been meaningfully rediscovered.
By assuming that a taxon must be proto-viable even if we only find one or two individuals, we risk trivialising the concept of global rediscovery and inflating the perceived rate of global rediscovery relative to the rate of global extinction. Which would then make it appear as if the current biodiversity crisis isn’t as bad as it is. As well as potentially offering false hope, which if actualised can hurt the reputation of conservation biology, de-incentivising public donations, resources and co-operation. To remedy this situation, I propose a unique interim conservation category, quasi-extant, to label taxa that have been discovered to technically be extant after being considered (probably) extinct but have not yet been shown to be proto-viable. It is also applicable to taxa that have been continuously sighted/reported, but whose numbers are now suspected to be so low as to call into question whether they are viable any more. Once a taxon has been shown to remain proto-viable after initially disappearing it can then be meaningfully reported as rediscovered and assigned to the appropriate conservation category, such as ‘Critically Endangered’ or ‘Endangered’. Or if the taxon proves not to be proto-viable, it should then be listed as functionally extinct, at which point human intervention and technology may or may not be able to assist in the recovery of its proto-viability status (Folch et al. 2009; Albani Rocchetti et al. 2022).
The error of assuming other individuals must exist
The implicit reasoning behind such a high rate of reporting of global rediscovery in the absence of known proto-viability (or greater) is plausibly explained by the belief that it is extremely unlikely that the individuals discovered actually represent the entire global population, given (1) the existence of suitable habitat, (2) the fallibility of targeted searches, (3) the very short window during which populations survive in a non-viable state, and (4) when young are recorded it implies relatively recent reproduction by other individuals that likely still exist. Each point can be addressed to show that it does not have any serious force.
Suitable habitat (1) is a necessary, not a sufficient, condition for the existence of a proto-viable population. Habitat destruction/degradation is a leading cause of extinctions, but many other threats (e.g., introduced species, hunting/poaching, illegal collecting) leave the broader habitat largely intact while driving individual taxa extinct. Which can be exacerbated by concomitant emerging threats such as inbreeding depression due to loss of reproductive connectivity. Therefore, suitable habitat only potentially indicates the existence of a viable population and cannot be used to infer the actual existence of such a population.
The fallibility of targeted searches (2) is perhaps best illustrated by the phenomenon of rediscovery. Successive failure to find a taxon that we later record, and hence can retrospectively know that we missed it previously. But the generic potential to miss one or more individuals, which might not even make the population proto-viable anyway, is evenly matched on the other side by the clear potential efficacy of taxon specific targeted surveys to find individuals from extremely small populations or even lone individuals (e.g., Chelonoidis abingdonii, C. phantasticus, Nesopta elliptica, Stenostomum tomentosum). Such considerations need to be applied on a case-by-case basis for one to potentially eclipse the other.
The window will be very short (3) in terms of relative duration compared with the long existence of the taxon, but the actual duration can be centuries for extremely long-lived organisms like giant tortoises and trees, and years for many if not most other species. During which they can still consist of a small number of fertile individuals, and therefore reproduction may still take place, so the mere observation of recent reproduction in a population (4) cannot be used to infer that it is still proto-viable. While the potential to find these last individuals is increased by the chance of luck, in addition to targeted surveys that may involve many people. Moreover, since we are in the midst of a biodiversity crisis, there will be many thousands of taxa that dip below a proto-viable level, so that even if any single population goes extinct rapidly in a non-viable state, there are so many such populations that the chance of finding individuals from non-viable populations in general is a virtual certainty.
Conclusion
Global rediscovery is not as simple as showing that a single individual remains extant. The ecology of a population is an important but often overlooked factor when reporting rediscoveries, which places inherent limits on how few individuals can manage to constitute a viable population. While the threats that have historically affected the taxon, and contributed to its decline and disappearance, often remain. While others can emerge as compound effects of other threats, such as inbreeding depression and population fragmentation. For putatively extinct taxa, and those considered functionally extinct, the discovery of one or more extant individuals should not move the needle much in terms of the conservation status of the population, and should instead be treated as quasi-extant until such time as they are shown to be proto-viable. At which point, they can be meaningfully reported as globally rediscovered, although this is very much the beginning of research and conservation, and certainly not the end.

Exscovery: Rediscoveries that refute global extinctions are special cases
By Branden Holmes. Published on 19 April 2025.
Introduction
The term ‘rediscovery’ in its global sense refers to the discovery of an extant population of a taxon that was not known to survive (or in rare cases, was thought to be functionally extinct). Three broad categories can be distinguished: (1) taxa that simply went unrecorded (hereafter ‘unlocated’) (e.g. Okutani, 1982; Gong et al., 2020); (2) taxa that had been unsuccessfully searched for in the past but were not regarded as (possibly) extinct (hereafter ‘lost’) (Long & Rodríguez, 2022; Lindken et al., 2024); and (3) taxa which were justifiably regarded as (possibly) extinct (e.g. Kandemir, 2009; Biton et al., 2013) as a result of adequate surveys (Fisher & Blomberg, 2011; Penedo et al., 2015). The first category is based on an arbitrary criterion, and the second is minimally informative, whereas the third is of immense importance. The critical distinction between these three categories is failed by the current reliance on the single cover-all term 'rediscovery'. This calls for a new term (‘exscovery’) to distinguish those special (and much rarer) cases of rediscovery in which a justified belief or claim of (possible) extinction is actively refuted.
Relocation
Category (1) treats time since last record as intrinsically meaningful, but this arbitrary criterion has rightly been rejected in its guise as the so-called ‘50-year rule’ introduced by the Convention on International Commerce of Species of Wild Flora and Fauna (CITES) to determine when to declare a taxon extinct (see Penedo et al., 2015). It should be noted that there are also temporal variants of category (2) (see Long & Rodríguez, 2022). There are no unsuccessful searches for unlocated taxa prior to their rediscovery, which are either relocated on the first attempt (e.g. Gower et al., 2006), or relocated through serendipity. There are at least two independent reasons to consider relocated taxa as bona fide rediscoveries s.l.1 (i.e. in the broad sense). Firstly, it is important to create baselines which will help enable us to detect future shifts and other net changes in biodiversity composition and abundance. But many unlocated taxa are known from very few specimens (Srivastava et al., 2015), which often do not currently allow for reliable population estimates (Lindken et al., 2024). And secondly, the extinction of a particular taxon is not contingent upon human knowledge of its current conservation status or the threats it faces. This is evidenced by the many so-called ‘dark extinctions’ that have presumably taken place (Boehm & Cronk, 2021). Confirmation of the persistence and population health of unlocated taxa is thus important, even if the categorization itself is arbitrary.
Rediscovery s.s.2
Category (2) is minimally informative because even taxa known to be extant in a particular area can fail to be recorded there by methodologically and seasonally appropriate surveys. Moreover, there is no guarantee of the overall quality of the search methodologies employed previously, which may have been rather informal. While many taxa have life history/demography/ecology traits (e.g. fossorial, fire ephemeral) that mean that they are expected to be rarely encountered anyway (Butchart et al., 2006; Fisher & Blomberg, 2011; Bell, 2021). At its closest to category (3), a lost taxon is only one adequate but failed survey away from being considered (possibly) extinct. The possible motivations to search for a taxon and thus disqualify it from category (1) are many and varied. Given our limited resources, it could be argued that it is best to only target those taxa most likely to be at risk of extinction. But the vast gaps in our knowledge means that there may be many unlocated taxa [category (1)] at great risk of extinction that have never been searched for, while lost taxa [category (2)] which have been unsuccessfully searched for may not be at risk of extinction at all. The need for baselines and the fact that extinction is knowledge-independent apply equally to category (2). Confirmation of the persistence and population health of lost taxa is thus important, but no more so by default than those taxa from category (1).
Exscovery
Category (3) is akin to epistemic de-extinction in that it refutes the real possibility (and not merely the hypothesis) of global extinction and is thus of the utmost importance. Yet it also raises questions. Whenever an officially extinct taxon is rediscovered s.l., it needs to be determined whether the extinction criteria themselves or their misapplication was to blame for the premature declaration. But whatever the circumstances that lead to the premature declaration, the fact that the taxon went unrecorded despite extensive surveys means it is almost certainly threatened with extinction and will likely remain that way for generations to come (Fisher, 2011; Scheffers et al., 2011). It may even be functionally extinct. Such taxa should be considered of the highest conservation priority, and yet to date there has been no nominal distinction made between any of the three categories outlined here in the literature. I therefore introduce the new term ‘exscovery’ (a portmanteau of ‘extinct’ and ‘rediscovery’) for taxa that belong to category (3).
This has the added benefit of making it far easier to find and track publications (and other materials) that report these highest and most profound rediscoveries s.l. through title and keyword searches via search engines. Instead of having to filter the much larger literature on rediscoveries in general, which includes innumerable non-global cases (i.e. local, in situ, or ex situ) (Holmes, 2024). This will help us to aggregate these cases, because exscovery has the deliberate benefit of allowing direct comparison between the total number of taxa that are currently considered (possibly) extinct with those that have been removed from there through discovery in the wild or ex situ. This is part of the broader project of looking into the causes and extent of turnover in lists of putatively extinct taxa (e.g. Keith & Burgman, 2004). And will ultimately help us to answer one of the most fundamental and perpetual questions in conservation biology: is the current rate of extinction slowing down or not?
Downplaying rediscovery s.l.
Taxa that are not known to survive can nevertheless still be justifiably believed to persist (Ladle et al., 2011), especially if they occur in known pristine habitat. Under the current scheme, we expect a proportionally high rate of rediscoveries s.l. relative to the rate of new declarations of (possible) extinction. The number of taxa for which there have been no records for decades or even centuries is very large (Long & Rodríguez, 2022; Martin et al., 2023; Lindken et al., 2024), with many having not been adequately searched for. Whereas taxa should only be considered (possibly) extinct if there have been adequate surveys that have failed to record them (Penedo et al., 2015). The concept of rediscovery s.l. is thus much broader than that of global extinction, and so there can be no direct comparison between them.
The public do not read the scientific literature for the most part and are therefore unlikely to be sufficiently informed about this. Potentially leading to unjustified public doubts about the severity of the current biodiversity crisis. If the public perception is that there are roughly as many taxa being profoundly rediscovered as are being declared extinct, then there is the risk that the public will think that we are not in fact in the midst of a biodiversity crisis, potentially extending to deep scepticisim of conservation biologists themselves and their competence. Especially if the rapid rate of discovery and description of new species, stories of which are often posted to social media, is additionally mistakenly interpreted to imply that the biosphere must be very healthy otherwise there would be far fewer taxa still extant to even discover and describe in the first place.
Beyond hypothetical scenarios regarding what the public may or may not understand or think, my anecdotal experience of global rediscovery stories posted to social media is that on occasion a user expresses their doubts as to the severity of the alleged biodiversity crisis in the face of “yet another” rediscovery. And since not everybody who reads a social media post interacts with it, this leads me to believe that there may be a significant level of public skepticism regarding the reality and extent of the current biodiversity crisis. By adopting the term ‘exscovery’ for profound cases of rediscovery, and spreading awareness about it, we can avoid potentially damaging public misperceptions of the seeming proliferation of global rediscoveries, all of which may falsely appear to be equally significant (Ladle et al., 2011).
Playing up rediscovery s.l.
Any taxon that has no known extant population can theoretically be extinct, even if its habitat seems pristine. Thus rediscovery s.l. is important so as to refute the extinction hypothesis (Ladle et al., 2011). The paucity of information (for little known taxa) or gaps in our knowledge (for better known taxa) can then be supplemented by new data, and thus we have the opportunity to more accurately assess the conservation status of a taxon. While this can also generate other relevant data on biogeography and population trends (Ladle et al., 2011). On the other hand, there are relevant differences between the three categories. Category (1) can only tell us about the status of the taxon. Category (2) tells us about the status of the taxon, and may (or may not) be able to tell us something about our search efforts. Category (3) tells us about the status of the taxon, and tells us a lot about our search efforts and the false conclusion we reached on their basis (or the interpretation of which). An important conservation lesson given the reality of the current biodiversity crisis.
Conclusion
The rediscovery s.l. of any taxon is important, even if it was believed to still exist despite the lack of records. At the same time, current usage of the term ‘rediscovery’ in the scientific literature (and beyond) is far too broad in the absence of distinct categories. This is artificially inflating the rate of rediscovery relative to global extinction, and risks appearing to the public that the current biodiversity crisis isn’t anywhere near as bad as us scientists are making out. By crafting a new term to distinguish those genuinely profound cases of rediscovery where global extinction is refuted, it helps to explicate the broadness of the term ‘rediscovery’ as currently used in conservation biology relative to the much narrower use of ‘extinct(ion)’. And therefore, the current relative rates of the two are not at all comparable, and thus a high rate of rediscovery s.l. should have little to no bearing on either professional or public perceptions of the severity of the current biodiversity crisis.
Notes
1 s.l. is an abbreviation for sensu lato, which means "in the broad sense". It may be helpful to think of the lines of latitude across the globe when you see "lato".
2 s.s. is an abbreviation for sensu stricto, which means "in the strict sense".

Fritsch's Quagga Photo (1864) taken in South Africa Has Been Rediscovered
By Branden Holmes and Jasper Hulshoff Pol. Published on 27 April 2024.
Artist Jasper Hulshoff Pol (website), with minor assistance from Branden Holmes, and confirmed by Dr. Peter Heywood, has rediscovered a stereophoto slide copy of a live Quagga photographed by Gustav Theodor Fritsch (1838-1927) in South Africa on 8 April 1864 (Fritsch, 1868).
Introduction
Africa is most often thought of as the continent that retains the largest proportion of its Late Pleistocene (c.126ka-11.7ka) megafauna (≥45kg), with the so-called "Big Five" (lion, leopard, rhinoceros, elephant, buffalo) only the tip of the biological iceberg. Alongside zebras, giraffes, Nile crocodiles, hartebeest, gnu (wildebeest), hippos, Greater kudus, Bongos, Great White sharks, Nile perch, Humpback whales, etc. etc. But palaeontological work over the last few decades has uncovered numerous large mammal (>5kg) extinctions, which are concentrated around the Late Pleistocene-Holocene border (13ka-6ka) (Faith, 2014). With the extinction rate increasing again after European colonisation, with the loss of taxa such as the Bluebuck (Hippotragus leucophaeus) (Hempel et al., 2024), the Cape warthog (Phacochoerus aethiopicus aethiopicus) (Grubb & d'Huart, 2010), the Bubal hartebeest (Alcelaphus buselaphus buselaphus) (IUCN SSC ASG, 2017) and the Senegalese giraffe (Giraffa camelopardalis senegalensis) (Petzold et al., 2020). One of the most famous of these latter disappearances is the Quagga (Equus quagga quagga), not least due to the long-term project (The Quagga Project) attempting to return its quasi-phenotype to southern African savannahs and grasslands (Parsons et al., 2007). It was last recorded in the wild in 1872 (Gippoliti et al., 2018), and the endling died in the Amsterdam Zoo on 12 August 1883 (Willoughby, 1966). It is one of relatively few extinct taxa for which 19th century photos of living individuals exist, and one of few to be the subject of multiple books (Barnaby, 1996; Green, 1996; Spreen, 2016; Heywood, 2022), and this latest photographic find emphasises the fact that research into the Quagga is very much ongoing.
The London Photos: All That Were Taken?
There are five surviving photos (see Appendix) of a Quagga (Equus quagga quagga) mare who resided in the London Zoo from 1851-1872, with her year of death seemingly coinciding with that of the last wild individual (Gippoliti et al., 2018). They were taken by Frank Haes (1863-1864) and Frederick York (1870) (Heywood & Dietrich, 2021), but the last of them was only published (and discovered?) more than a century later in 1991 (Huber, 1991, 1994). And even then, the details of the photographs have been made clearer by further research (Edwards, 1996; Fuller, 2013; Heywood & Dietrich, 2021). Today these five photos are now all freely available on the internet as they are in the public domain, including as part of the Wikipedia article on the subspecies. But it is sometimes stated that she was the only Quagga ever photographed alive (e.g. Huber, 1994; Wikipedia). However, it has been known by a handful of researchers that Gustav Theodor Fritsch (1838-1927), a medical doctor, took at least one (and possibly multiple) photos of a living specimen at the farm of Andrew Hudson Bain, 'Quaggafontein', on 8 April 1864, which was used to produce a photoxylograph (Fritsch, 1868; Barnaby, 1996; Heywood & Dietrich, 2021):
Above: a photoxylograph of a Quagga in South Africa. Reproduced from (Heywood & Dietrich, 2021), who reproduced it from (Fritsch, 1868).
The production of a photoxylograph involves the photochemical transfer of a photographic image onto a woodcut block prior to carving, and the fate of the original photograph/s is unknown (Heywood & Dietrich, 2021). The background has been noted as less photograph-like (Heywood & Dietrich, 2021), suggesting that multiple photographs may have been taken that were used as reference material for the stone wall and window shutters by the woodblock carver (Ibid., p. 8):
"Most probably, in our view, the wood engraving used to produce Figure 1 was reconstructed from other photographic images of these animals as the stone wall in the background with the window and shutters was drawn separately from other reference material and looks less ‘photographic’ than do the animals."
However, it must be noted that Jasper is of the opinion that the photoxylograph was produced from this stereophoto.
The Rediscovery of Fritsch's (1864) Photo
In December 2022, painter Jasper Hulshoff Pol noticed a listing for a slide of a Quagga in a July 1879 catalogue from Max Fritz (Fritz, 1879:8), and set about trying to track it down in case it was a 'new' photograph. Consequently, I sent him the Heywood & Dietrich (2021) paper about the photoxylograph, hoping that it might turn out to be a copy of the original photo. After reading the paper, Jasper searched for Gustav Fritsch and came across an eBay listing of a stereophoto of a zebra made by Gustav Fritsch. He purchased it, and when it arrived he noticed that it was the same image as Fritsch's photoxylograph, only mirrored due to the transfer process involved in photoxylography. I suggested that he contact Dr. Peter Heywood, who happily confirmed that the slide depicts the same Quagga as the photoxylograph (Peter Heywood, pers. comm. to Jasper Hulshoff Pol, December 2022):

A Stereophoto: One Photo, Two Images
The original Max Fritz catalogue listing (Fritz, 1879:8) appears to be for a magic lantern slide for use in projection, which Jasper's slide copy is not. The original eBay listing for Jasper's slide stated that it was a stereophoto, implying that it was taken with a camera that uses two lenses centimetres apart to simulate our slightly different left and right eye positions (see Sleightholme et al., 2016:Fig. 4). When a stereophoto is viewed through a stereoscope it produces a three-dimensional image (Ibid.). This is consistent with some minor differences between the two images that can be seen below, showing that they are taken from slightly different angles: 1) The front legs are more open in the right image, 2) the white object on the ground between the rear legs is obscured more in the left image, 3) the shadow on the back of the right front leg is a different shape, and 4) the duck under the Quagga is in a different position relative to the front and back legs of the latter. Several other possible differences are harder to confidently distinguish given the blurrier quality of the left image.
Above: a side-by-side comparison of the two frames of the slide, with minor differences between them noticeable. Indicative of a stereophoto, in line with the original eBay listing.
Fritsch' Zebra, A True Quagga?
Heywood & Dietrich (2021) provide two lines of evidence to argue that the zebra Fritsch photographed on 8 April 1864 was a true Quagga and not a 'bonte' (striped) Quagga (i.e. Burchell's zebra, E. q. burchelli). The first was the degree of lack of stripes that goes beyond known cases of lesser-striped Burchell's zebra (i.e. no leg striping and reduced body striping), and the second was Fritsch's precision of language in describing the animal as a Quagga and not a bonte Quagga in full knowledge of the difference (Ibid.). Upon receiving a copy of the slide from Jasper via email, Dr. Heywood raised the fact that the slide lists the animal as a 'bonte Quagga' (i.e. well striped Burchell's zebra) and disagreed with this designation, reiterating the first line of argumentation made in his joint paper:
"Clearly, it's the same quagga illustrated in our paper and yet the description terms it "bonte" (striped) and names it as Equus burchelli. I have to disagree with this designation as leg stripes are absent and the body striping is reduced. In fact, the degree of body striping is similar to that in several museum specimens and illustrations labelled as "quagga.""
(Peter Heywood, pers. comm. to Jasper Hulshoff Pol, December 2022)
Conclusion
The evidence shows that Gustav Theodor Fritsch took a stereophoto (that produced two images from slightly different angles) of a Quagga on 8 April 1864 in South Africa. With Jasper's discovery of two images on a single stereoscopic slide bringing the total number of images of living Quaggas to at least eight or none: five photographs from London including at least one stereoview (resulting in at least six images), and one stereophoto (two images) and one photoxylograph (one image) (for nine total images), or, one stereophoto (two images) that were used to produce a photoxylographic version of them (for a total of eight images).
The fact that the reverse of the slide falsely identifies the zebra as a 'bonte Quagga' (Equus burchelli) may have prevented the significance of the slide from being recognised earlier. Although copies of such slides must now be relatively rare and not likely to be encountered very frequently. This raises the important possibility that other visual depictions of living Quaggas may await discovery/recognition, so long as the degree of lack of striping can be sufficienty seen to rule out lesser-striped examples of Burchell's zebra (Equus quagga burchelli).
