Scutosaurus karpinskii

Reptilia - Pareiasauridae

Taxonomy

Pareiosaurus karpinskii was named by Amalitzky (1922). Its type specimen is PIN 2005/1532, a skeleton, and it is a 3D body fossil. Its type locality is Sokolki locality, PIN 2005, which is in a Severodvinian/Vyatkian terrestrial horizon in the Salarevo Formation of the Russian Federation. It is the type species of Scutosaurus.

It was recombined as Scutosaurus karpinsky by Hartmann-Weinberg (1930); it was recombined as Scutosaurus karpinskii by Lee (1997), Lee (2000), Ivakhnenko (2008).
