Family Phascolarctidae Owen, 1839 Phascolarctidae gen. et sp. indet.

Fig. 7C .

Material.—QM F52287 (left dentary fragment) from Chinchilla Rifle Range, Australia, Pliocene.

Remarks.—This large dentary fragment appears to be morphologically distinct from all other known koala dentaries (Price et al. 2009). However the lack of diagnostic characters on the specimen means it can only be referred to Phascolarctidae gen. et sp. indet.
