TheromorpJia.— This order is divided into the Pelycosauria and Anomo- dontia. The beaked Saurians were somewhat lizard-like, but were synthetic types, combin- ing the characters of the Ich- tliyosaurs, the turtles, the Sphenodon, with those of liz- ards, Dinosaurians, and crocodiles. The skull was short, and in Dicynodon the jaws in front had the nipping, horny beak of a turtle, while from behind in the upper jaw pro- truded two long, curved, canine teeth. Dicynodon fic/rireps Owen, had a skull about half a metre'(30 inches) Fig. 449.—Posterior view of ttie skull of IchtKyomuriis; lettering as in Fig. 443, with following additions ; Bo, basiocci- pital ; Exo, Exoccipital ; Sup. 0, supra- occipital ; Opo, opisthotic ; Stap, supra- stapedial or hyomandibnlar.—After Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Packard, A.
