Taxonomy & Nomenclature

Synonym/s: Zaglossus hackettii Glauert, 1914:244

 

Conservation Status

Last record c. 38,000 BC?

 

Distribution

Western Australia, Australia

 

Biology

A species of echidna which was apparently more upright in its posture than living echidnas, on account of its much longer limb bones (Glauert, 1914). It is invariably described as being the size of a sheep, with Wikipedia citing an estimate of 100kg. However, Johnson (2006) gave a far more modest estimate of 30kg.

 

Hypodigm

Only known from fragmentary remains including "atlas vertebra, the clavicles and episternum, the pelvic girdle, two femora, a tibia and a radius" (Glauert, 1914). All known material is believed to be in the WA Museum's collection.
