Description
Nikkasaurus, named after Russian paleontologist Nikolay Kalandadze, was a small therapsid, with a skull about 5 cm long. The eyes had large orbits and sclerotic rings, and the head was tilted back, as with all therapsids. The skull looks superficially similar to those of the pelycosaurs, in particular members of Varanopidae.
Biology
Nikkasaurus was probably mainly insectivorous, and possibly nocturnal.
Systematics
The only known species is the type species N. tatarinovi, described by MF Ivahnenko in 2000, from the Middle Permian Mezen River Basin. Nikkasaurus is possibly a relic of a more ancient stage of therapsid development.[1][2]
