. Elements of geology : a text-book for colleges and for the general reader. Geology. Fig. 690.— Teleosaurus brevidens: a, skull; 5, side view of snout showing the teeth (after Phillips). Fig. 689.—Paddle of a Pliosaurus, x ^. Plesiosaurus. A perfect paddle of this animal has been found seven feet long (Fig. 689); the animal was probably at least forty feet long. Intermedi- ate between this group and the next—inhabit- ers both of land and water — Croccdilians existed in great numbers, and of great size. Some, like the Teleosaurus (Fig. 690), were narrow-snouted like the Ga- vials of the Ganges, but had amphiccelous vertebrae like the Enaliosaurs. 2. Dinosaurs.—Among these were the largest reptiles—in fact, the largest land-animals—that have ever existed. They were also in many respects the highest of all reptiles, since they possessed many charac- ters which connected them closely with mammals, and especially with birds. Connecting: Characters.—The most important of these were: (1.) Large, hollow limb-bones and firm sacrum composed of several consoli- dated vertebrae. These characters show that these animals walked with a free step, the body well borne above the ground, like mammals and birds, and did not crawl in the manner of reptiles. (2.) In many cases the hind-legs were very large and long, and the fore-legs very small in comparison. This, together with the backward elongation of the ischium (Fig. 691 B)—suitable for erecting the body—show that some * Williston, Science, vol. 16, p. 262, 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 LeConte, Joseph, 1823-1901.
