Australopithecus anamensis is a hominin species that lived approximately between 4.3 and 3.8 million years ago [1] [2] and is the oldest known Australopithecus species, [3] living during the Plio-Pleistocene era.
Australopithecus anamensis. Discovery Date: 1995. Where Lived: Eastern Africa (Lake Turkana, Kenya and Middle Awash, Ethiopia) When Lived: About 4.2 to 3.8 million years ago. Overview: Australopithecus anamensis has a combination of traits found in both apes and humans.
A. anamensis is the earliest known australopithecine and lived over 4 million years ago. Background to discovery. Age. Fossils range in date from 3.8 to 4.2 million years ago. Important fossil discoveries.
Australopithecus anamensis. The earliest member of the genus Australopithecus is Au. anamensis, which was discovered in northern Kenya near Lake Turkana at Kanapoi and Allia Bay. The species was first described in 1995 after an analysis of isolated teeth, upper and lower jaws, fragments of a cranium, and a tibia unearthed at the discovery sites.
This species is often called “Lucy’s ancestor”, which refers to the famed skeleton of the later species Australopithecus afarensis nicknamed “Lucy”. In 2019, the face of Australopithecus anamensis was finally revealed in a nearly complete fossil cranium.
…known for its fossils of Australopithecus anamensis, an early hominin (member of the human lineage) dating to between 3.9 and 4.2 million years ago. Among these fossils is a relatively complete shinbone with features indicating that A. anamensis walked on two legs.
The researchers who discovered the skull say it belongs to a species called Australopithecus anamensis, and it gives scientists their first good look at the face of this hominin.
In eastern Africa, the first known australopith appears in the fossil record at 4.1 million years ago as Australopithecus anamensis (Leakey et al. 1995). This species is relatively poorly known but preserves evidence of postcanine megadontia and bipedal locomotion.
Australopithecus was an adaptive radiation of hominins that lived 4.2-2 million years ago. Who were these tough-chewing, ground-dwelling bipeds? What do they tell us about our early evolution?
Fossils attributed to Australopithecus anamensis (which means “southern ape of the lake,” from “anam” or lake in the Turkana language) have been recovered from sites in the Turkana Basin in Kenya (Allia Bay and Kanapoi) as well as in Ethiopia (Middle Awash and Woranso-Mille).
