Eosaurus.—In the Coal-measures of Xova Scotia, in 1861, Prof. Marsh found the vertebrae of what he thinks, with some reason, was a marine Saurian; an order which is large- ly developed in the Mesozoic. But as only the bodies of a few vertebrae have been found, and as the bi-concavity of these is the chief evidence of marine Saurian affinity and as bi-concavity also exists among Laby- rinthodonts, Huxley believes this was also a Labyrinthodont. There is, therefore, still some doubt as to the true affinity of this animal. The size of some of the vertebra? was two and a half inches in diameter, indi- cating a reptile of gigantic di- mensions. Many other genera have been described by au- thors both in Europe and America. Among these, Baphetes, Eaniceps, Hyler- peton, Hylono- mus, and Am- phibamus from America, and Anthracosaurus, Ophiderpeton, and Apa- teon from Europe, are best known. The Baphetes and the Anthra- cosaurus attained gigantic Fig. 582.—Two Vertebrae of Eosaurus Acadianus (after Marsh)..
