Priscagamidae Borsuk-Białynicka and Moody, 1984
(figs. 54A, 55A, 56A)
DEFINITION: All taxa sharing a more recent common ancestor with Priscagama gobiensis than with Agama agama .
DIAGNOSIS: Phrynosomimus asper , Mimeosaurus crassus , and Priscagama gobiensis are united in this analysis to the exclusion of all other chamaeleontiforms based on three unambiguous synapomorphies: 8(1) presence of dermal sculpturing on the maxilla, 50(1) dermal rugosities on the postorbital process of the jugal, and 97(1) postorbital extending ventrally for less than one-half the orbital margin.
COMMENTS: Preliminary analyses ( Conrad, 2005a) suggests that Arretosaurus ornatus shows some affinities with priscagamids. Inclusion of that taxon in a comprehensive analysis requires a re-visitation of its morphology.
