About Platycepsion
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.
