Protemnodon was a genus of megafaunal macropodids that existed in Australia, Tasmania, and New Guinea in the Pliocene and Pleistocene.

Taxonomy[]

Recent analysis of mtDNA extracted from fossils indicates that Protemnodon was closely related to Macropus.[2] The species formerly known as Protemnodon bandharr and Protemnodon buloloensis have been moved to a new genus, Silvaroo.

Description[]

Restoration of Protemnodon anak

Based on fossil evidence, Protemnodon is thought to have been physically similar to wallabies, but generally larger and more robust. Protemnodon nombe was the smallest in the genus, weighing about 45 kg; Protemnodon roechus was the largest in the genus, weighing around 170 kg.[3]

Several species of Protemnodon survived up until around 50,000 years ago. Two species, P. nombe and P. tumbuna, may have survived in the highlands of Papua New Guinea as recently as 12,000 years BC.[4]
