They lived alongside robust australopithecines
like Paranthropus, which would coexist with various species of Homo for the next million years.
A group of species called robust australopithecines

About two million years ago there appears to have been a diversification of forms among the slender australopithecines, which are probably related to the first forms of the genus Homo, on the one hand, and the robust australopithecines
, on the other.
Many scientists regard these creatures as ancestors of both the lineage that led to modern humans and of another, now-extinct evolutionary lineage known as robust australopithecines
The eating habits of ancient hominids known as robust australopithecines
have been a matter of debate for decades.
She's already proposed that the unusual tooth proportions of robust australopithecines

by some investigators, which first appeared about 2.
This cerebral radiator -- represented in fossils by grooves in cranial bones and openings for emissary veins -- expanded as brain size increased in gracile australopithecines and the Homo lineage, while small-brained Hadar hominids and robust australopithecines
lacked the cooling network of veins.
5-million-year-old hominid species to which the famous Lucy belongs, and the robust australopithecines
-- a hominid lineage that emerged around 2 million years ago and died out 1 million years later -- show a contrasting venous drainage pattern.
