Homotherium is an extinct genus of machairodontine scimitar-toothed cat that inhabited North America, South America, Eurasia, and Africa during the Pliocene and Pleistocene epochs from around 4 million to 12,000 years ago. In comparison to Smilodon, the canines of Homotherium were shorter, and it was probably adapted to running down rather than ambushing prey.
Hadar or Hadar Formation is a paleontological fossil site located in Mille district, Administrative Zone 1 of the Afar Region, Ethiopia, 15 km upstream (west) of the A1 road's bridge across the Awash River.
Paranthropus aethiopicus is an extinct species of robust australopithecine from the Late Pliocene to Early Pleistocene of East Africa about 2.7–2.3 million years ago. However, it is much debated whether or not Paranthropus is an invalid grouping and is synonymous with Australopithecus, so the species is also often classified as Australopithecus aethiopicus. Whatever the case, it is considered to have been the ancestor of the much more robust P. boisei. It is debated if P. aethiopicus should be subsumed under P. boisei, and the terms P. boisei sensu lato and P. boisei sensu stricto can be used to respectively include and exclude P. aethiopicus from P. boisei.
The Omo River in southern Ethiopia is the largest Ethiopian river outside the Nile Basin. Its course is entirely contained within the boundaries of Ethiopia, and it empties into Lake Turkana on the border with Kenya. The river is the principal stream of an endorheic drainage basin, the Turkana Basin.
Meave G. Leakey is a British palaeoanthropologist. She works at Stony Brook University and is co-ordinator of Plio-Pleistocene research at the Turkana Basin Institute. She studies early hominid evolution and has done extensive field research in the Turkana Basin. She has Doctor of Philosophy and Doctor of Science degrees.
Palaeoloxodon recki, often known by the synonym Elephas recki is an extinct species of elephant native to Africa and West Asia from the Pliocene or Early Pleistocene to the Middle Pleistocene. During most of its existence, the species represented the dominant elephant species in East Africa. The species is divided into five roughly chronologically successive subspecies. While the type and latest subspecies P. recki recki as well as the preceding P. recki ileretensis are widely accepted to be closely related to Eurasian Palaeoloxodon, the relationships of the other, chronologically earlier subspecies to P. recki recki and P. recki ileretensis are uncertain, with it being suggested they are unrelated and should be elevated to separate species.
Koobi Fora refers primarily to a region around Koobi Fora Ridge, located on the eastern shore of Lake Turkana in the territory of the nomadic Gabbra people. According to the National Museums of Kenya, the name comes from the Gabbra language:
In the language of the Gabbra people who live near the site, the term Koobi Fora means a place of the commiphora and the source of myrrh...
The Omo Kibish Formation or simply Kibish Formation is a geological formation in the Lower Omo Valley of southwestern Ethiopia. It is named after the nearby Omo River and is subdivided into four members known as Members I-IV. The members are numbered in the order in which they were deposited and date between 196 ka ~ 13-4 ka. Omo Kibish and the neighboring formations have produced a rich paleoanthropological record with many hominin and stone tool finds. The Kibish formation, in particular, is most notable for Richard Leakey's work there in 1967 during which he and his team found one of the oldest remains of anatomically modern Homo sapiens. Known as Omo Kibish 1, the fossil was dated to 196 ± 5 ka old and is among two other Omo remains that were found in Member I. The Omo fossils were more recently re-dated to approximately 233 ± 22 ka old. In the early 2000s a research boom enriched the knowledge base about the Kibish Formation. Study of the faunal remains and stone tools provided insight into the archeological associations of Homo sapiens and thereby their behaviors and the complex environmental contexts in which they lived and evolved.
Gorgopithecus is an extinct genus of primate in the Old World monkey family Cercopithecidae, closely related to the baboons. There is only one known species, Gorgopithecus major. It has been found at sites from the Pliocene and Early Pleistocene Epoch in South Africa and Tanzania. It was first discovered at the Kromdraai A site in South Africa. It has since been found from Swartkrans, South Africa. Most recently, it has been recognized from the DKI site in Bed I of Olduvai Gorge, Tanzania, which has been dated to 1.8 million years old.
Euthecodon is an extinct genus of long-snouted crocodile. It was common throughout much of Africa during the Neogene, with fossils being especially common in Kenya, Ethiopia, and Libya. Although superficially resembling that of gharials, the long snout was a trait developed independently from that of other crocodilians and suggests a diet of primarily fish. Euthecodon coexisted with a wide range of other crocodiles in the areas it inhabited before eventually going extinct during the Pleistocene.
Paracamelus is an extinct genus of camel in the family Camelidae. It originated in North America and crossed the Beringian land bridge into Eurasia during the Late Miocene, approximately 7.5–6.5 million years ago (Ma). It is the presumed ancestor to living camels of the genus Camelus.
The Usno Formation is a palaeontological formation located in Ethiopia. It dates to the Pliocene period.
Gondolin Cave is a fossiliferous dolomitic paleocave system in the Northwest Province, South Africa. The paleocave formed in the Eccles Formation dolomites. Gondolin is currently the only described hominin-bearing fossil site in the Northwest Province-portion of the designated Cradle of Humankind UNESCO World Heritage Site. The cave is located on privately owned land and is not accessible to the public. As is the case with other South African Paleo-cave systems with Pliocene and/or Pleistocene fossil deposits, the system was mined for lime during the early 20th century. As a result, the system has been heavily disturbed and consists of only a small active cave, a series of in situ remnant cave deposits, and extensive dumpsites of ex situ calcified sediments produced during mining activities.
The greater Turkana Basin in East Africa determines a large endorheic basin, a drainage basin with no outflow centered around the north-southwards directed Gregory Rift system in Kenya and southern Ethiopia. The deepest point of the basin is the endorheic Lake Turkana, a brackish soda lake with a very high ecological productivity in the Gregory Rift.
Anna Katherine "Kay" Behrensmeyer is an American taphonomist and paleoecologist. She is a pioneer in the study of the fossil records of terrestrial ecosystems and engages in geological and paleontological field research into the ecological context of human evolution in East Africa. She is Curator of Vertebrate Paleontology in the Department of Paleobiology at the Smithsonian Institution's National Museum of Natural History (NMNH). At the museum, she is co-director of the Evolution of Terrestrial Ecosystems program and an associate of the Human Origins Program.
Enhydriodon is an extinct genus of mustelids known from Africa, Pakistan and India that lived from the late Miocene to the early Pleistocene. It contains 9 confirmed species, 2 debated species, and at least a few other undescribed species from Africa. The genus belongs to the tribe Enhydriodontini in the otter subfamily Lutrinae. Enhydriodon means "otter tooth" in Ancient Greek and is a reference to its dentition rather than to the Enhydra genus, which includes the modern sea otter and its two prehistoric relatives.
The KBS Tuff is an ash layer in East African Rift Valley sediments, derived from a volcanic eruption that occurred approximately 1.87 million years ago (Ma). The tuff is widely distributed geographically, and marks a significant transition between water flow and associated environmental conditions around Lake Turkana shortly after 2 Ma.
Rhinocolobus is an extinct genus of monkey closely related to modern colobus monkeys. It lived in eastern Africa during the Plio-Pleistocene, existing as recently as 1.5 million years ago.
