Equatorius

Equatorius is an extinct genus of kenyapithecine primate found in central Kenya at the Tugen Hills.[1] Thirty-eight large teeth belonging to this middle Miocene hominid in addition to a mandibular and partially complete skeleton dated 15.58 Ma and 15.36 Ma. were later found.[2]

Analysis

The anatomical structures in part was seen to be similar to Afropithecus and Proconsul. Nevertheless, anatomy and morphology suggested the genus had an increased terrestrial habitat.[3]

Taxonomy

Ward et al. 1999, using their previous published study of K.africanus, based the separate definition on comparisons of gnathic and dental anatomy.[4] The classification's validity was subsequently challenged.[5]
