Platycepsion wilksoni is an extinct species of prehistoric amphibian, known from partial skeleton deposited in shale at the Gosford Quarry site of the Terrigal Formation in Australia. This specimen may represent a larval stage, as denoted by the presence of external gills, making it the first evidence of larval development in stereospondyls.[3]
Taxonomy
The species is assigned to a currently monotypic genus, the synonym Platyceps wilkinsonii, a name published in 1887 by the Australian palaeontologist
colubrid genus of snakes. Another revising author John W. Cosgriff named the species as the type for a new genus, Blinasaurus,[4] unaware of Kuhn's replacement of the name, and placed a second species in the same genus, later separated to a new combination as Batrachosuchus henwoodi.[5]
The author noted the epithet Wilkinsonii in the first description as commemorating the deputy chair of the
C. S. Wilkinson.[1]
