Palaeoanthropology (communication arising): Sahelanthropus or 'Sahelpithecus'?

  title={Palaeoanthropology (communication arising): Sahelanthropus or 'Sahelpithecus'?},
  author={Milford H. Wolpoff and Brigitte Senut and Martin Pickford and John Hawks},
Beginning with Ramapithecus, there has been a continued search for an ape-like hominid ancestor in the Miocene Epoch. Sahelanthropus tchadensis is an enigmatic new Miocene species, whose characteristics are a mix of those of apes and Homo erectus and which has been proclaimed by Brunet et al. to be the earliest hominid. However, we believe that features of the dentition, face and cranial base that are said to define unique links between this Toumaï specimen and the hominid clade are either not… 

Further details concerning fossils attributed to Sahelanthropus tchadensis (Toumaï) : research in action

The fossils attributed to Sahelanthropus tchadensisl/Ig from the Late Miocene of Chad are of great scientific and cultural importance, and are the subject of debate as to whether they represent a

The results not only confirm that Sahelanthropus tchadensis cranium is a hominid but also reveal a unique mosaic of characters that is most similar to Australopithecus, particularly in the basicranium.

Late Miocene Teeth from Middle Awash, Ethiopia, and Early Hominid Dental Evolution

Fossil hominid teeth recovered from Ethiopia's Middle Awash suggest that the last common ancestor of apes and humans had a functionally honing canine–third premolar complex.

Paleoenvironments, Paleoecology, Adaptations, and the Origins of Bipedalism in Hominidae

The discovery of 6 Ma bipedal Orrorin in a heavy woodland to forest paleoenvironmental setting indicates that bipedalism most likely evolved in relatively closed vegetation formations of the kind

For many years molecular studies suggested that the hominid family emerged during the Pliocene. But today we have good evidence of hominids in African Upper Miocene strata. Reconstructing our

The Spine of Australopithecus

The vertebrae discussed in this chapter are from five sites in East and South Africa: Aramis, Asa Issie, and Hadar from the Afar Depression of Ethiopia and Sterkfontein and Malapa in the Cradle of Humankind, South Africa.

Basion to biporion (BSBIP) does not effectively distinguish P. troglodytes from Plio-Pleistocene hominids and humans when used univariately, basion to bicarotid (BSBIC) can be used to test whether or not an unknown specimen is a hominid.

Potential Hominoid Ancestors for Hominidae

Human origin and evolution are a prominent topic among scientists, one on which there continues to be disagreement. Each new finding raises new questions and arguments. This chapter summarizes the

Australopithecus anamensis: a finite-element approach to studying the functional adaptations of extinct hominins.

Information obtained from both finite-element analyses and dental macroanatomy leads us to suggest that A. anamensis was probably adapted for habitually consuming a hard-tough diet and may imply that this hominin species was well adapted to puncture crushing.



Notes on Ramapithecus, the earliest known hominid, and Dryopithecus.

  • D. Pilbeam

It is concluded that Ramapithecus is the earliest known hominid, some 5 or 6 times older than the oldest Pleistocene hominids.

Cranial morphology of Australopithecus afarensis: a comparative study based on a composite reconstruction of the adult skull.

The Pliocene hominid species Australopithecus afarensis is represented by cranial, dental, and mandibular remains from Hadar, Ethiopia, and Laetoli, Tanzania and appears to retain a primitive, rather than derived, morphology.

A new hominid from the Upper Miocene of Chad, Central Africa

The discovery of six hominid specimens from Chad, central Africa, 2,500 km from the East African Rift Valley, suggest that the earliest members of the hominids clade were more widely distributed than has been thought, and that the divergence between the human and chimpanzee lineages was earlier than indicated by most molecular studies.

Australopithecus africanus: The Man-Ape of South Africa

TOWARDS the close of 1924, Miss Josephine -*- Salmons, student demonstrator of anatomy in the University of the Witwatersrand, brought to me the fossilised skull of a cercopithecid monkey which,

Australopithecinæ or Dartians

The Dartians are ground-living anthropoids, human in posture, gait and dentition, but still anthropoid in facial physiognomy and in size of brain, much easier to say there was a ‘Dartian’ phase in man's evolution than to speak of one which was ‘australopithecine’.

The story of human origins in Africa takes a twist with the description of a 6–7-million-year-old cranium from Chad. The discovery hints at the likely diversity of early hominids.

The Supraorbital Torus: "A Most Remarkable Peculiarity" [and Comments and Replies]

It was concluded that the torus functions to resist bending stress concentrated over the eyes during anterior biting and that its development is proportional to the amount of such stress which cannot be resisted by the unadorned frontal bone.

Strain orientation data corroborate the hypothesis that the strepsirrhine face is twisted during mastication and suggest the existence of two distinct loading regimes, possibly associated with masseter or medial pterygoid contraction.
