 Australopithecus ramidus

 Ardipithecus ramidus

Australopithecus ramidus would be assigned to Ardipithecus ramidus using the alpha taxonomy

Original diagnosis:"distinguished from A. afarensis by the following: upper and lower canines larger relative to the postcanine teeth; lower first deciduous molar narrow and obliquely elongate with large protoconid, small and distally placed metaconid, no anterior fovea, and small, low talonid with minimal cuspule development; temporomandibular joint without definable articular eminence; absolutely and relatively thinner canine and molar enamel; lower third premolar more strongly asymmetrical, with dominant, tall buccal cusp and steep, posterolingually directed transverse crest; upper third premolar more strongly asymmetric, with relatively larger, taller, more dominant buccal cusp" (White, et al: 306)

herc logo presents precise geographic locations and current best date estimates for late Miocene, Pliocene, and Pleistocene sites with human ancestor (hominin) fossils and archaeology. Several interactive visual interfaces allow users to generate maps and tables that relate localities, fossils, tools, and evolutioanry events with geography and time. The data content is dynamic and is updated daily, as are new interface features. This site started as a course syllabus for Anthropology 3101: Human Evolution 2 at California State University, East Bay, and grew with each quarter it was used. Now has over 200 sites and hundreds of bibliographic citations.
