“Pelycosaur”-Grade Synapsids: Introductione anatomy of eothryidids and varanopids from the western United States is introduced, as well as a new taxon of large-bodied varanopid from Germany. A functional analysis of possibly semiaquatic habits in the purported piscivorous taxon . is introduced.

Phylogeny and Taxonomy of the Traversodontidaephyletic Gomphodontosuchinae is recovered, as suggested by previous analyses. The distribution of traversodontids is discussed, with Gondwana and especially Africa suggested as the ancestral area for Gomphodontia and Traversodontidae.
