What is "paranthropus"

Paranthropus (from Greek παρα, para "beside"; άνθρωπος, ánthropos "human") is a genus of extinct hominins. Also known as robust australopithecines, they were bipedal hominids that probably descended from the gracile australopithecine hominids ( Australopithecus) 2.7 million years ago. Members of this genus are characterised by robust craniodental anatomy, including gorilla-like sagittal cranial crests, which suggest strong muscles of mastication, and broad, grinding herbivorous teeth. However, Paranthropus skulls lack the transverse cranial crests that are also present in modern gorillas.
