Anterior Dental Cutting in the Laetolil Hominids and the Evolution of the Bicuspid P3
The younger Laetolil hominids provide evidence of a unique anterior cutting complex with a chisel-like action occurring between the lingual-distal C face and a transverse ridge on the P, perpendicular to it, extending between the subequal cusps. An earlier adaptation to more efficient grinding may have resulted in reduced canine projection and the development of the lingual P3 cusp, raising the...
متن کاملPhylogeny of early Australopithecus: new fossil evidence from the Woranso-Mille (central Afar, Ethiopia).
The earliest evidence of Australopithecus goes back to ca 4.2 Ma with the first recorded appearance of Australopithecus 'anamensis' at Kanapoi, Kenya. Australopithecus afarensis is well documented between 3.6 and 3.0 Ma mainly from deposits at Laetoli (Tanzania) and Hadar (Ethiopia). The phylogenetic relationship of these two 'species' is hypothesized as ancestor-descendant. However, the lack o...
متن کاملIsotopic dietary reconstructions of Pliocene herbivores at Laetoli: Implications for early hominin paleoecology
Major morphological and behavioral innovations in early human evolution have traditionally been viewed as responses to conditions associated with increasing aridity and the development of extensive grassland-savanna biomes in Africa during the PlioPleistocene. Interpretations of paleoenvironments at the Pliocene locality of Laetoli in northern Tanzania have figured prominently in these discussi...
متن کاملMandibular Ramus Posterior Flexure: A Sex Indicator in Homo sapiens Fossil Hominids?
Accurate determination of sex in skeletal human samples is very important in anthropological and demographic studies. Recently, Loth and Henneberg have suggested that a new osteological criterion on the mandible, the mandibular ramus posterior flexure (MRPF) had a high sex discriminating effectiveness. A preliminary test applied to a few hominid mandibles (including Australopithecines, Homo ere...
متن کاملA New Horned Crocodile from the Plio-Pleistocene Hominid Sites at Olduvai Gorge, Tanzania
BACKGROUND The fossil record reveals surprising crocodile diversity in the Neogene of Africa, but relationships with their living relatives and the biogeographic origins of the modern African crocodylian fauna are poorly understood. A Plio-Pleistocene crocodile from Olduvai Gorge, Tanzania, represents a new extinct species and shows that high crocodylian diversity in Africa persisted after the ...
