The Lukeino Formation is a geologic formation located in Kenya and it dates to the Late Miocene (Messinian).[1]
The Lukeino Formation is believed to have been formed through continued tectonic plate activity, and it was located within a well-forested region[3] that was located nearby to Paleolake Lukeino.[2]
History
From 1971 to 1978, Martin Pickford had carried out extensive research in the Tugen Hills under a permit issued by the Kenyan Office of the President.
In 1974, Pickford found the first hominid fossil from the Lukeino Formation, a lower molar, which is included within the holotype of Orrorin tugenensis.[1] The rest of the holotype was found by Pickford and Brigitte Senut in 2000.[4]
Pierre & Pickford (2006) described eight hundred new micromammal fossils from the Kapsomin Member were described.[5]
Altner & Reichenbacher (2015) named the first fish from Paleolake Luekino: Kenyaichthys kipkechi.[6]
A P4 discovered at the Lukeino Formation has been proposed to belong to an amphicyonid by Morales et al. (2016), as both its age and dimensions are similar to Bonisicyon.[7]
