A new petauroid possum (Marsupialia,Pseudocheiridae) from the Pliocene Bluff Downs Local Fauna,northern Queensland

Pseudochirops winteri n. sp. is described from the Pliocene Bluff Downs Local Fauna on the basis of a left dentary fragment with M₂. It is considered to be most similar to P. archeri although its phylogenetic position must remain tentative until further material is found. The presence of this presumably rainforest-dwelling possum, the first from this fauna, may indicate a limited closed forest component. Given the paucity of additional rainforest taxa recovered from this site despite extensive screen washing, however, such a component must have been restricted to gullies or riparian fringes.
