Procolophonia is an extinct
Anapsida or "Parareptiles" (as opposed to the Eureptilia
).
Classification
There are two main groups of Procolophonia, the small, lizard-like
sister taxon of Procolophonia by many studies, however recently discovered material places it within the group, as the sister taxon of Procolophonoidea.[2]
The following cladogram is simplified after the phylogenetic analysis of MacDougall and Reisz (2014) and shows the placement of Procolophonia within Parareptilia. Relationships within bolded terminal clades are not shown.[2]

Relationship to turtles
The procolophonians were traditionally thought to be ancestral to the
Archosauria).[3]
This placement within the diapsids suggests that the turtle lineage lost diapsid skull characteristics as it now possesses an anapsid skull.
