Shuvosaurinae

Shuvosaurinae is a subfamily within the family Poposauridae, named by Chatterjee (1993), and anchored on the genus Shuvosaurus.

In a 2007 study Chatterjeea was demonstrated to be a junior synonym of Shuvosaurus, and the therein cladistic analysis found that Shuvosaurus, Effigia and Sillosuchus all form a closely related group. However, this group was left nameless, and simply referred to as Group Y. However, in accordance with ICZN rules of naming priority Shuvosauridae has priority over Chatterjeeidae (Shuvosauridae being named in 1993, while Chatterjeeidae was named in 1995).
