'Bolosaurids' are an
extinct family of
anapsid reptiles from the
Permian Period.
Fossils have been found in
North America,
Russia and
Germany. The bolosaurids were unusual for their time period by being
bipedal, the oldest known
tetrapods to have been so. Their teeth suggest that they were
herbivores. The bolosaurids were a rare group and died out without any known descendants.
