Simosthenurus occidentalis (Glauert, 1910:31)

Giant short-faced kangaroo, Western sthenurine kangaroo (proposed)



Taxonomy & Nomenclature

Synonym/s: Sthenurus occidentalis Glauert, 1910:31; Simosthenurus orientalis Tedford, 1966


Conservation Status


Last record: Late Pleistocene


Subfossil remains of this species from a 33-27,000 year old layer have been uncovered from Tight Entrance Cave, southwestern Australia (Prideaux, 2007:17). However these may have been worked from older sedimentological levels, and further analysis is need to resolve their true age. The species may have only persisted until c.50ka, or even older.
