Polyglyphanodontidae Gilmore, 1942b (figs. 54C, 55C, 56B) DEFINITION: Adamisaurus magnidentatus, Gilmoreteius ferrugenous, Gobinatus arenosus, Polyglyphanodon sternbergii, and all descendants of their last common ancestor. DIAGNOSIS: Polyglyphanodontids are diagnosed by 9(0) absence of dermal sculpturing on the prefrontal, 77(0) pineal foramen lying within the parietal, 119(0) presence of a pterygoid-vomer contact, 122(1) pterygoids contact at midline, 213(1) marginal teeth waisted, 261(0) straight (non-angulate) clavicle, and 266(1) secondary scapular fenestra present. COMMENTS: Estes (1983) and Presch (1983) considered the taxa contained here in Polyglyphanodontidae to be a subclade of Teiidae (see comments above for Teiidae). New data regarding the dentition of Polyglyphanodon sternbergii from an excellent study by Nydam and Cifelli (2005) will be incorporated into future versions of this analysis.
