They were carniv- orous, and powerful swim- mers, and common in the Ju- rassic seas of Europe; one form existed in the Jurassic times in Wyoming. Order 7. 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) 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.
