Excerpt from Proceedings of the Academy of Natural Sciences of Philadelphia, 1870 Their lateral borders are much more obtuse, and they terminate in a broad, thick, notched point. The ends bordering the notch are most thickened and porous, apparently indicating the attachment of a long moveable snout. The nasals do not rise from the forehead in the vaulted manner so conspicuous in Sivatherium and Rhinoceros, but, as previously indicated, simply continue the curvature of the forehead. One of the most remarkable characters of the fossil is the greater extent backward of the lateral nasal notch than in Sivatherium. In this it ceases far forward of the position of the horn cores, situated above the orbits. In the Colorado fossil the notch continues back and beneath the position of the horn cores, where the nasals apparently become continuous with the maxillaries. The relative position of the orbits cannot be ascertained, as all the contiguous parts are broken away. They appear to have been situated behind the position of the horn cores. It is probable that the fossil may pertain to the same animal as the remains from the Manvaises Terres of Nebraska, described under the name of Titanotherium, but in the state of extreme uncertainty as to its collocation, it may with equal probability be referred to other genera, perhaps to Megalomeryx, or it may have been an American species of the Sivatherium. Under the circumstances it may be referred to a new genus, with the name of Megacerops Coloradensis. Prof. O. C. Marsh, of Yale College, exhibited a number of vertebrae of a new Dinosaurian from the cretaceous green sand near Barnsboro , N. J. He observed that they indicated a reptile allied to Hadrosaurus Foulkii Leidy, but only about one half the size of that species. The specimens, although all found in the same immediate neighborhood, were apparently portions of three different individuals, only one of which was fully adult. They consisted of several dorsal and lumbar vertebrae belonging to the Museum of Yale College, and an anterior caudal vertebra recently presented to the collection of the Academy by Dr. Leidy. These remains appear to be quite distinct from those already described, and apparently belong to the same species, for which Prof. Marsh proposed the name Hadrosaurus minor. Prof. Marsh also showed the tooth of a new and very large Mosasaurus from the cretaceous of North Carolina. It belonged to a very perfect right upper jaw, formerly in the collection of the late Dr. Emmous, and now in the cabinet of Williams College. The teeth of the specimen are remarkably short and thick, nearly round at the base and their surface entirely without facets. The remains preserved indicate a species of great, size, probably sixty feet in length, but with a head and muzzle comparatively short. It was named Mosasaurus crassidens. A peculiar caudal vertebra of a somewhat similar reptile from the lower cretaceous marl bed, near Hornerstown, N. J., was likewise exhibited. It is oue of a series in the museum of Yale College, and indicated a new Mosasaurus of medium size, apparently belonging to the genus Leiodon. The articular surfaces for the attachment of the chevron bones were in nearly the same plane as the lower surface of the vertebra, and not impressed as in Macrosaurus prorigerand other allied species The presence of well developed diapophyses in this part of the caudal series was another peculiarity of these vertebrae, and indicated that the animal had a broad, muscular tail. The species was therefore named Leiodon lalicaudus. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at<
