was a primitive therapsid
that lived 260 mya in the late Permian
("zone II"). This anomodont
was discovered in Kotelnich
on the Vyatka River
Russia. It is found in sandstone
sediment, so most likely this represents a delta dwelling species, but this is not conclusive, as other habitats may have been involved but the species was never fossilized in that habitat. The species mainly has teeth that are heavily abraded suggesting plant material of high silica
The teeth were quiet large for its size containing a single cusp per tooth with many cerations as in a cerated knife. These teeth were replaced throughout its lifecycle.
