Eodicynodon Assemblage Zone

From Wikipedia, the free encyclopedia

The Eodicynodon Assemblage Zone is a geological stratum and a faunal zone of the Beaufort Group, of the South African Karoo. The name refers to Eodicynodon, a small herbivore and the earliest genus of dicynodont mammal-like reptile, whose fossils have been found in that structure.

Eodicynodon was a therapsid reptile of the Capitanian stage (266-260 million years ago) of the Permian Period. It measured about 30 cm. (11.8 inches) long. The length of the skull was 9 cm. (3.5 inches).
