Fossil Hominins, the Bipedal Primates

Human origins and evolution: Cold Spring Harbor, deja vu.

TLDR
Work on a stratigraphically thick and temporally deep sedimentary sequence in the Middle Awash study area of Ethiopia's Afar Depression reveals an assembly order of hominid anatomies and behaviors that was impossible for Darwin to discern.

Ardipithecus ramidus and the Paleobiology of Early Hominids

TLDR
Ardipithecus ramidus indicates that despite the genetic similarities of living humans and chimpanzees, the ancestor the authors last shared probably differed substantially from any extant African ape.

40Ar/39Ar dating in paleoanthropology and archeology

TLDR
The conventional K‐Ar technique has given way to 40Ar/39Ar dating as the method of preference, which is not only more precise and accurate when dating ideal materials, but also permits excellent ages to be obtained from situations that often stymie the conventional K-Ar technique, such as dating of contaminated tuffs and altered rocks.

Revised calibration of the geomagnetic polarity timescale for the Late Cretaceous and Cenozoic

Recently reported radioisotopic dates and magnetic anomaly spacings have made it evident that modification is required for the age calibrations for the geomagnetic polarity timescale of Cande and

A new geomagnetic polarity time scale for the Late Cretaceous and Cenozoic

We have constructed a magnetic polarity time scale for the Late Cretaceous and Cenozoic based on an analysis of marine magnetic profiles from the world's ocean basins. This is the first time, since

Four-million-year-old hominids from East Lake Turkana, Kenya.

A piece of mandible and several isolated teeth are reported from fluviatile sediments older than 4 million years at East Lake Turkana. They most closely resemble hominids from Laetoli, Tanzania and

Pliocene hominid partial mandible from Tabarin, Baringo, Kenya.

TLDR
Although fragmentary, the preserved morphology of the Tabarin mandible is consistent with the diagnosis of the Pliocene hominid Australopithecus afarensis and can be distinguished from all other currently recognized hominoid taxa.

Ecological and temporal placement of early Pliocene hominids at Aramis, Ethiopia

TLDR
Radioisotopic dating, geochem-ical analysis of interbedded volcanic ashes and biochronological considerations place the hominid-bearing deposits in the Middle Awash research area of Ethiopia's Afar depression at around 4.4 million years of age.

Australopithecus ramidus, a new species of early hominid from Aramis, Ethiopia

TLDR
The antiquity and primitive morphology of A. ramidus suggests that it represents a long-sought potential root species for the Hominidae.

New discoveries of Australopithecus at Maka in Ethiopia

TLDR
The discovery of new fossils from Maka, dated to 3.4 Myr ago, provide powerful support for the interpretation of A. afarensis as a single, ecologically diverse, sexually dimorphic, bipedal Pliocene primate species whose known range encompassed Ethiopia and Tanzania.
