Ancient human ancestor

The fossils of Ranapithecus, sivapithecus, and Australopithecus are considered as the ancient human fossils. These fossils were supposed to be originated from a common ancestor of both apes and man i.e (hominoids)

  1. Dryopithecus- They existed about 25 million years ago. Its fossil discovered from Asia and Africa. It has semi erect posture and hand and legs of equal size.


  1. Ranapithecus
    • It is the earliest known direct ancestors of man which existed about 14 million years ago.
    • Its fossil is also recorded from shivalik hill in India and lake of victory in Australia.
  • Its fossil is also recorded from dang valley of Nepal
  • They were partially erect with small canine teeth.
  • They were arboreal having men like feeding habit


  1. Sivapithecus

Its fossil were similar to that of ramapithecus which existed about 10 million years ago. Their fossils were recorded from shivalik.


  1. Australopithecus-

–It is the human like from which existed about 5 million years ago in dry land of Africa

— They weigh about 40-50 kg and were about 3.5 to 5 feet tall.

— The brain capacity or (cranial capacity) is 600 cc

— They used weapons of bones

— They walked erect and had long sized canine and incisors teeth which help in tearing

— Fossil record suggest that Australopithecus has 2 species i.e Australopithecus  Africanus  and Australopithecus robustus.   Australopithecus robstus remain unchanged and became extinct while Australopithecus Africanus continued to change and evolved to form modern man.
