Early human ancestor from 2.5 million years before present.

Introduction

Australopithecus garhi is an extinct fossil hominin species identified from remains discovered between 1990 and 1998 at the Bouri locality, in the Middle Awash region of the Afar Regional State, Ethiopia. The remains of this species, which date to roughly 2.5 Ma based on argon-argon dating techniques, are composed of unassociated cranial and postcranial elements discovered over some 9 sq. km. Hypotheses for conspecificity for some of these elements are based on proximity at the time of collection; the more distant remains are associated primarily based on discovery in the same or temporally similar geological horizons.

Anatomy

The cranium (as known from holotype specimen BOU-VP-12/130) is characterized by extremely large postcranial dentition, well within the range of the robust group, Paranthropus, and it possesses a notable sagittal crest. However, this species lacks several anatomical traits...
