A juvenile Toxochelys latiremis (Testudines, Cheloniidae) from the Upper Cretaceous Niobrara Formation of Kansas, USA

Matzke, Andreas T.


Remains of a well preserved juvenile skull of Toxochelys latiremis are described in detail and compared with a juvenile specimen of the closely related turtle Ctenochelys stenoporus. Both juveniles have a similar size and are comparable in the stage of their ontogeny. Many significant osteological differences between these two turtles regarding the quadrate, prootic and dentary are found and summarized here.
