Mosasaur fossils found in Japan in 1990s may be of new species: research

OSAKA - A research team from Okayama University of Science and other institutions said Wednesday that fossils of a mosasaur, a large marine reptile that lived between 80 million and 65 million years ago, found in Osaka Prefecture in the early 1990s may be of a new species.

The fossils, discovered in Kaizuka between 1990 and 1992, have been kept at the Natural History Museum, Kishiwada City, in Osaka Prefecture. But a thorough analysis had not been conducted because of a lack of equipment capable of removing the surrounding rock.
