Plio—Pleistocene hominid discoveries in Hadar, Ethiopia

Nature, 1976
The International Afar Research Expedition has now recovered remains of twelve hominid individuals from geological deposits estimated to be ∼ 3.0 Myr in Hadar, Ethiopia. A partial skeleton represents the most complete hominid known from this period. The collection suggests that Homo and Australopithecus coexisted as early as 3.0 Myr ago.

Plio-Pleistocene African Climate

Science, 1995
Marine records of African climate variability document a shift toward more arid conditions after 2.8 million years ago (Ma), evidently resulting from remote forcing by cold North Atlantic sea-surface temperatures associated with the onset of Northern Hemisphere glacial cycles.

Morphometric variation in Plio‐Pleistocene hominid distal humeri

American Journal of Physical Anthropology, 1996
The magnitude and meaning of morphological variation among Plio-Pleistocene hominid distal humeri have been recurrent points of disagreement among paleoanthropologists. Some researchers have found noteworthy differences among fossil humeri that they believe merit taxonomic separation, while others question the possibility of accurately sorting these ...

Plio-Pleistocene calcareous plankton biochronology

Marine Micropaleontology, 1989
Abstract A reliability assessment of 20 commonly employed Late Pliocene and Pleistocene calcareous plankton biostratigraphic datums published for 30 DSDP holes has revealed a subset of ten which appear to be reasonably isochronous and consistently recognizable by a large number of biostratigraphers.

Variations in Plio-Pleistocene Deposition in the Red Sea

2018
The thickness of deep-water Plio-Pleistocene (PP) sediments in the Red Sea varies somewhat, as expected from increased biogenic pelagic production rates in the south and with input of aeolian and fluvial sediments through the Tokar Gap in the Sudanese hills.

Paleotemperature Variations across the Plio-Pleistocene Boundary

Science, 1971
Strong variations in the O 18 /O 16 and C 13 /C 12 ratios occur through the type section for the Plio-Pleistocene boundary, but the boundary itself is not characterized by unusual isotopic gradients.

Comparative context of Plio-Pleistocene hominin brain evolution

Journal of Human Evolution, 2001
One of the distinguishing features of Homo sapiens is its absolutely and relatively large brain. This feature is also seen in less extreme form in some fossil Homo species. However, are increases in brain size during the Plio-Pleistocene only seen in Homo, and is brain enlargement among Plio-Pleistocene primates confined to hominins?

Femoral lengths and stature in Plio‐Pleistocene hominids

American Journal of Physical Anthropology, 1991
AbstractThis study reports the femoral lengths of 31 Plio‐Pleistocene hominids dated between 3.1 and 0.7 million years ago, and uses those lengths to estimate stature by way of the femur‐stature ratio reported by Feldesman et al. (Am. J. Phys. Anthropol. 78:219–220, 1989).

The Plio-Pleistocene Boundary and Mammalian Correlation

Geological Magazine, 1948
The problem of the boundary between the Pliocene and the Pleistocene is still very far from satisfactorily settled both from a geological and from a faunal viewpoint. It becomes increasingly apparent that the two aspects of the problem require different definitions and in consequence there has been very great confusion in the application of the terms ...
