Otsheria is an extinct genus of anomodont, in the infraorder venyukovioidea. It lived in modern-day Russia during the Permian.[1]
The genus is named for the Ochyor region where it was discovered in 1960, and the type species is Otsheria netzvetajevi.[2]
The holotype, a skull lacking a mandible (PIN 1758/5), is the only Otsheria fossil extant. The skull is 10.5 centimetres (4.1 in) in length, with large eye sockets and a short, broad snout. The skull suggests four incisors and nine short, flattened maxillary teeth. The canines are undifferentiated. The shape of the teeth and skull both suggest a mouth adapted for cutting plant parts, which in turn suggests a herbivorous or omnivorous diet.[3]
