Toyotamaphimeia machikanensis is an extinct tomistomine crocodylian which lived in Japan during the Pleistocene. A specimen recovered in 1964 at Osaka University during the construction of a new science building has been dated to around 430–380 thousand years old based on the stratum in which it was found.[1] T. machikanensis was a fairly large crocodylian with a 1 m (3.3 ft) skull and a total length up to 8 m (26 ft).[2] It is closely related to the false gharial and was originally described as a member of the same genus, Tomistoma.
