Chelonoidis marcanoi Turvey et al., 2017:4
Taxonomy & Nomenclature
The taxonomic status of C. marcanoi is disputed:
"Shortly after the publication of C. marcanoi, Albury et al. (2018) and Vlachos (2018) considered the species a nomen dubium because the elements used to erect it are morphologically similar and poorly diagnostic among species of Chelonoidis... More diagnostic elements collected from cave deposits in the southwest Dominican Republic indicate that C. marcanoi is a senior synonym of C. dominicensis."
(Viñola-López & Almonte, 2022:19,11)
Extinct or invalid (nomen dubium)
Last record: Holocene
