Sthenurinae

Mounted skeleton of Simosthenurus occidentalis in the Victoria Fossil Cave, photographed by ccdoh1.


Belongs within: Macropodidae.

The Sthenurinae include the fossil short-faced kangaroos, some of which are among the largest known kangaroos. The banded hare-wallaby Lagostrophus fasciatus has been suggested to be the only surviving member of the sthenurines, but its position remains controversial.

Characters (from Long et al. 2002): Skulls relatively short and deep, with wide rostra and thick ectotympanic bones. I1-3 tending to form narrow V-shaped arcade; I3 with elongate crown relative to I1 and I2. Lower jaws often fused at symphysis. Premolars usually wide, high-crowned, complex; molars with crenulated enamel, postlink crest on rear of upper molars; lower molars often with well-developed premetacristid blade extending forward to join paracristid. Digits I and IV on fore foot often greatly reduced, digits II and III elongate; hind foot usually with all digits except IV reduced or lost. Astragalus with high, rounded crests on tibial surface.
