A new fossil species of frog of the Australian limnodynastid genus Limnodynastes Fitzinger from the Oligocene Kangaroo Well Local Fauna of the Northern Territory and tabulation of ilial features of all extant and extinct species

Abstract

A new species of the limnodynastid genus Limnodynastes Fitzinger is described from the Oligocene Kangaroo Well Local Fauna on the Deep Well pastoral station in the Northern Territory. The material comprises the proximal portions of a left and right ilium and is named L. waterhousae. The new species appears to be most similar to L. antecessorTyler, 1990 from Oligo-Miocene sites at Riversleigh, Queensland. The major characteristics of the ilium of all 30 extant and extinct Australian frog genera are summarised.
