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.

[3] The species is assigned to a currently monotypic genus, the synonym Platyceps wilkinsonii, a name published in 1887 by the Australian palaeontologist William Stephens, was nominated as the type.

A revision in 1964 by Oskar Kuhn assigned the species to the genus Platycepsion to replace the earlier combination, which was invalidated by an earlier use of the name Platyceps for a 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 Linnean Society of New South Wales, C. S.
