Remains of Australopithecus consisting of an almost complete skull of a young individual, probably not more than five years of age were first discovered in 1924 at Taungs in Bechuanaland, South Africa, and were studied by Prof. Raymond Dart. The separation was complete by the Pliocene time. Again Australopithecus approaches man in the character of the enlarged cranium; highly arched forehead; position of the orbits; downward face: position of uncial plane; faint supraorbital ridges; relatively interiorly placed foramen magnum, etc. Ramapithecus sensu stricto is known only from the Indian Siwaliks and the author suggests that the transition from Ramapithecus to a still unknown Australopithecus took place in the same region prior to their migration into Africa and Southeast Asia. • Dryopithecus A genus of extinct apes, fossils of which have been found in Europe and Asia and dated to the mid-Miocene (about 16–7 million years ago). This condition is occasionally met with in contemporary man, but rarely seen among the anthropoids. The genetic title dryopithecus means oak wood apes because it is believed that the environmental conditions were such at that time with densely forested tropical lowlands and the members might have been predominantly herbivorous. The premolars and molars are very large. The lower jaw of Meganthropus of Java combines certain characteristics of A. africanus with those of A. robustus: Meganthropus might provisionally be called “Australopithecoid”. 12.

Though Sivapithecus is slightly larger than Ramapithecus, the two fossils are closely related and are believed to be the ancestors of the modern orangutan. The right lateral incisor is somewhat smaller than the left. Recent paleontological analysis of the Higher Primate subfamily Dryopithecinae shows that fossils in this group can be referred to two genera, Ramapithecus and Dryopithecus.Ramapithecus is known from India and East Africa in Late Miocene or Early Pliocene time (about 14 m. years ago). In the modern era most researchers now agree that Dryo-pithecus and Sivapithecus are great apes, but there is dis-agreement on their relations to living taxa. Disclaimer Copyright. Publish your original essays now. The skull contained twenty milk teeth and four permanent first molars in good condition. The jaw is massive. And for "Kenyapithecus wickeri" we might refer to the recent study of Andrews (1971) : the lower jaw has sectorial premolars … 5. Sivapithecus (Shiva's Ape) (syn: Ramapithecus) is a genus of extinct apes.Fossil remains of animals now assigned to this genus, dated from 12.2 million years old in the Miocene, have been found since the 19th century in the Siwalik Hills of the Indian subcontinent as well as in Kutch.Any one of the species in this genus may have been the ancestor to the modern orangutans. The short, deep face of Ramapithecus has led some anthropologists to suggest that perhaps it could not use teeth as weapons to the same extent as Dryopithecus, and that Ramapithecus used hands for hunting and defence. Hooton, however, pointed out that “young apes have smaller brow-ridges, higher foreheads; lesser jaw projection, and a more horizontal and forward position of the foramen magnum than the adults of the species.”. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. The molar teeth are very large but quite humanoid. 1. Middle Pleistocene deposits of Kromdraai, two miles east of Sterkfontein, yielded fossil remains of two individuals to which Dr. Broom gave the scientific name Paranthropus robustus.
