Nanoparia is anextinctgenus ofpareiasaur that lived in thePermian.

Description

[edit]
Restoration

It was about 60 cm (23.6 in) in length, and weighed around 8 to 10 kilograms (17.6-22 lbs).

Classification

[edit]

This is an unusual small, spiny specialised form. The skull is very similar to that ofPareiasaurus and Romer considered it a synonym of the latter. Orlov however (in Osnovy Paleontology, the monumental multi-volume Russian textbook of Paleontology) placed it in theElginiinae. Kuhn (1969) however argues that while resemblingElginia in the ossifications at the rear of the skull, it differs completely in proportions and would not seem to be related. Lee (1997) considers it a basal member of the dwarf pareiasaurs.Nanoparia is believed to be among thepareiasaurgenera most closely related toturtles.[1]
