The genus
Dorcopsoides was described in 1967 from a well-preserved lower jaw, skull fragments, and
occipital found in the
Upper Miocene Alcoota Fossil Beds north-east of
Alice Springs in the
Northern Territory. It was part of the Alcoota local fauna, which also included
zygomaturine diprotodonts, a type of
mihirung (
Ilbandornis), a crocodile (
Baru) and the giant thylacine,
Thylacinus potens. It was about the size of a
gray and black four-eyed opossum. The generic name,
Dorcopsoides, indicates a resemblance to forest wallabies (
Dorcopsis) now living in
New Guinea and neighboring islands. ==References==
