Orrorin is an extinct genus of primate within Homininae from the Miocene Lukeino Formation and Pliocene Mabaget Formation, both of Kenya. The type species is O. tugenenesis , named in 2001, [ 1 ] and a second species, O. praegens , [ 2 ] assigned to the genus in 2022.

2024年1月3日 · Living around 6 million years ago, Orrorin tugenensis is the one of the oldest early humans on our family tree. Individuals of this species were approximately the size of a chimpanzee and had small teeth with thick enamel, similar to modern humans.

While the hominin status of Sahelanthropus, Orrorin, and Ardipithecus species may be debated, their significance for understanding human origins and evolution is clear. They open a window into...

Orrorin tugenensis is one of the earliest hominins whose fossils were recovered from four areas in the Tugen Hills region of Kenya (Cheboit, Kapsomin, Kapcheberek, and Aragai). “Orrorin” means “original man” in the local Tugen dialect, and “tugenensis” pays tribute to the Tugen Hills region.

The genus name Orrorin means ‘original man’ in the Tugen language, whereas the species name tugenensis was assigned because the fossils were found in the Tugen Hills of Kenya. Distribution. Fossils have been found at four sites (Cheboit, Kapsomin, Kapcheberek, and Aragai) in the Tugen Hills, Kenya. Relationships with other species

2023年10月10日 · Scientists have attributed them to five species in three genera: Sahelanthropus, Orrorin, and Ardipithecus. Each of these fossil species shares some traits with better-known human relatives from later in time, like Australopithecus.

Orrorin Tugenensis: Pushing back the hominin line. The Kenya Palaeontology Expedition (KPE) report in December 2000 the discovery of what is almost certainly a new species of hominid at Kapsomin in Kenya's Baringo district; see the BBC news story; for background, see family trees. The excavating team includes Martin Pickford from the KPE and ...

Nicknamed “Millenium Man” due to its timely discovery, the fossils were dated to ~6 mya and given the taxonomic classification, Orrorin tugenensis (“original man from the Tugen hills”). Initially many paleoanthropologists were skeptical, especially since the fossils were not made available to the scientific community.

Orrorin tugenensis. Dated to around 6 million years ago; the name means “original man” in Tugen, the African language spoken in the region, and tugenensis refers to the discovery site, the Tugen Hills of western Kenya. This site is within the region affected by frequent volcanism in the Miocene and Pliocene eras, so the bones can be dated ...

Orrorin Tugenensis is considered the second-oldest (after Sahelanthropus) known hominin ancestor that is likely related to modern humans. The species lived between 6.2 and 5.8 million years ago and is the only species classified in the Orrorin genus.
