A crocodile fossil discovered when excavating for the construction of a new School of Science building for Osaka University in 1964. Judging from the geological stratum, it is believed that the fossil dates from 430,000 to 380,000 years before. The fossil has received world recognition as a rare specimen from this period, and upon reexamination by Ryosuke Aoki has been advocated to receive a new biological classification as a new species, i.e. 'Toyotamaphimeia Machikanense.' There are points concerning the scientific name and original state of the fossil which remain unconfirmed and we await the research of specialists on this valuable fossil.
