The earliest-known Antelopes are Miocene, but the largest and most extraordinary fossil examples of this family are two gigantic four-horned Antelopes, which occur in the Pliocene strata of the Sivalik Hills of India, and have been described under the names of Sivatherium and Bramatherium. The Bovidm, or Ox tribe, has hitherto only occurred in rocks not older than the Pliocene or Post-pliocene. At this latter period England alone possessed four oxenâviz., the Lithua- nian Aurochs {Bos bison or Bos priscus), the Wild Bull or Urus {Bosprimtgenius), the Bos antiquus, and a small aboriginal species, the Bos longifrons, believed by Owen to be " the source of the domesticated cattle of the Celtic races before the Roman ; Order VII. IIyracoidea.^-T\ns little order, represented at the present day by no more than the single genus Hyrax, is not known to have any fossil representatives. Order VIII. Proboscidea.âThis order, including no other living forms than the Elephants, came into existence in the Miocene period, where it is represented by all its three sec- tions, Deimtkeriunii Mastodon, and Fig. 242.âSkeleton oi Mastodon. The Deinotherium (fig. 222) was a gigantic Miocene Mam- mal, probably something like the living Elephants, but having no incisors in the upper jaw. In place of these, the lower jaw was furnished with two long tusk-like incisors, which were bent downwards. In most essential respects the Mastodons (fig. 242) resemble the ElephaVits, but the molar teeth were furnished with nipple- shaped eminences. Usually there are two tusk-shaped upper â ncisors, but sometimes lower incisors are present as well. Please note that these images are extracted from scanned page images that may have been digit
