Hominid Humeral Fragment from Early Pleistocene of Northwestern Kenya

  title={Hominid Humeral Fragment from Early Pleistocene of Northwestern Kenya},
  author={Bryan Patterson and William W. Howells},
  pages={64 - 66}
The distal end of a hominoid humerus was recovered from early Pleistocene sediments in the Kanapoi drainage near the southern end of Lake Rudolf. Lava capping the sediments yielded a potassium/argon date of 2.5 million years. The fragment can be distinguished on inspection from gorilla and orangutan; discriminate analysis of humeri of Homo and Pan assigns it as hominid. From other evidence we consider it more likely to represent Australopithecus s.s. than Paranthropus. 
Early hominid ulna from the Omo basin, Ethiopia.
Results from multivariate morphometric analyses show that this bone is unique in shape among the extant hominoids although it is most similar to Pan and Homo. Expand
Early Hominid Humerus from East Rudolf, Kenya
A fossil hominid humerus discovered in 1970 by the expedition to East Rudolf, Kenya, led by R. E. F. Leakey is examined in comparison with a large series of extant hominoids and shows the uniqueness of the fossil among thehominoids. Expand
Early Elephantidae of Africa and a Tentative Correlation of African Plio-Pleistocene Deposits
Comparisons of the many remains of fossil elephants in sediments of Plio-Pleistocene age in Africa allow a lineage specific identification of the fossils and thus provide a means of stratigraphically correlating these deposits. Expand
Remains of Hominidae from Pliocene/Pleistocene Formations in the Lower Omo Basin, Ethiopia
Discoveries by the Chicago contingent of the 1967 and 1968 International Research Expedition to the Omo Valley extend the fossil records of australopithecines back to between 3 and 4 million yearsExpand
Early hominid from Baringo, Kenya
Palaeontological evidence and comparative molecular studies of modern hominoids suggest that major evolutionary changes occurred in the African Hominoidea between 14 Myr and 4 Myr1–3. Unfortunately,Expand
Morphological Trends and Phylogenetic Relationships from Middle Miocene Hominoids to Late Pliocene Hominids
It is perhaps too early to posit certain morphological continuities in the Neogene fossil record of Hominoidea since there are still so many hiatuses, both temporal and geographical. Nevertheless,Expand

A unique late Pliocene to early Holocene sedimentary sequence, dating from before 4.2 to about t.8 million years, is established, extending the known time span and the enigmatic dichotomy of these early hominids. Expand
Contributions from Southern and Eastern Africa to the study of early hominid evolution
Our understanding of earliest human evolution (Pliocene/early Pleistocene) is presently based primarily on fossil discoveries from South and East Africa. Different sorts of information have beenExpand
The geological context of the Kanapoi fossil hominids
Recent study of the geological succession at Kanapoi reveals that there are at least three series of sediments younger than the early Pliocene Kanapoi sediments which repose unconformably on them.Expand
New four-million-year-old hominid species from Kanapoi and Allia Bay, Kenya
The mosaic of primitive and derived features shows this species to be a possible ancestor to Australopithecus afarensis and suggests that Ardipithecus ramidus is a sister species to this and all later hominids. Expand
