A new kind of prehistorical animal, Dinedentosaurus Oliveiral, a large grass-eating reptile that lived in Southern Brazil some 175,000,000 years ago, has been mounted for public exhibit at the Museum of Comparative Zoology by George Nelson, Preparator-in-Chief.

Discovered on a Harvard fossil expedition to Brazil, by Liewellyn I. Price and Theodore E. White, Research Assistants, the new species of reptile was named in honor of the late Professor E.P. de Oliveiria, head of the Brazil Geological Survey, who greatly assisted the Harvard scientists in the field. The expedition uncovered a rich new bed of ancient fossils, yielding several hitherto unknown reptile.

The newly-mounted reptile, eight feet long and four feet high, belonged to a sterile branch of the early family which later gave rise to mammals and which is known to scientists as dicynodonts, or two-tuskers. The dicynodents ranged from the size of a rat to about the size of a small horse, and reached their greatest development in South Africa.
