New hominin postcranial remains from locality OMO 323, Shungura Formation, Lower Omo Valley, southwestern Ethiopia

Résumé

With sediments that range from 3.6 Ma to 1.05 Ma (Feibel et al., 1989), the Shungura Formation has yielded numerous hominin fossils from more than 110 localities (Howell et al., 1987; Boisserie et al., 2008). Among them, the locality OMO 323 is of major paleoanthropological interest because in 1976 it yielded the oldest cranium securely attributed to Paranthropus boisei sensu stricto, OMO 323-1976-896, dated to approximately 2.12 Ma (see below for additional details regarding geological context; Alemseged et al., 2002). It has also yielded an unassociated talus that has been alternately likened to that of Paranthropus (Deloison, 1997) or Homo (Berillon, 2000; Gebo and Schwartz, 2006). Here we describe a metatarsal, a phalanx, and a radius from the same locality, together with the geological context of their discovery.
