Genus Paranthropus is a group of extinct hominids that inhabited parts of Africa between two and one million years ago. This genus includes several species such as Paranthropus boisei, Paranthropus robustus, and Paranthropus aethiopicus. These hominids were popularly called "robust australopithecines" for their larger jaws and teeth in comparison to other early hominids. They were similar to Australopithecus in many ways, but their unique physical characteristics set them apart. These hominids can also be referred to as robust hominids, megadont hominids, or simply Paranthropines reflecting their classification within the family of hominids. Despite their differences from other early hominids, Paranthropus species were still believed to be on a side branch of the human lineage.
