Fossil anthropoid teeth. Collection of fossil teeth from anthropoid members of the primate evolutionary tree, dating to 38 to 39 million years ago (Eocene). These fossils were found in the Dur At-Talah escarpment in Libya. The fossil teeth are from: Talahpithecus parvus, Afrotarsius libycus, and Biretia piveteaui. It is thought that the ancestors of modern primates originated in Asia, with branches spreading to Africa, eventually giving rise to the ancestors of humans.
