Type species
Nimbacinus dicksoni
Muirhead & Archer, 1990[1]
Other species
  • Nimbacinus richi Murray & Megirian, 2000

The genus Nimbacinus contains two species of carnivorous, quadrupedal marsupials in Australia both of which are extinct:

  • Nimbacinus dicksoni Muirhead & Archer, 1990[1]
  • Nimbacinus richi Murray & Megirian, 2000[2]

Like all thylacinids, Nimbacinus dicksoni was a dog-like marsupial, though its smaller size makes its appearance more comparable to that of a fox. Unlike its relatives, its jaws were likely strong enough for it to take down prey larger than itself.[3]

The name of the genus combines Nimba and cinus, derived from a word meaning "little" in the Wanyi language, indigenous peoples associated with the Riversleigh fossil site, and the Ancient Greek word kynos, meaning dog.[1]

Taxonomy

The description of N. richi was published in 2000 by researchers Peter F. Murray, working at the Museum of Central Australia and Dirk Megirian of the Northern Territory Museum. The holotype is fossilised material excavated at "Top Site" at the Bullock Creek fossil area, a partial left dentary with a premolar and several molars that is dated to the mid-Miocene. The specific epithet commemorates Tom Rich, who introduced the authors to the site of their discovery.[2]
