Lukeino Formation, and then after surveys were conducted from 1998 onwards by the Kenya Palaeontology Expedition led to the discovery of new material within the Aragai Member, a site situated in the lower levels of the Lukeino Formation. Most of the collection consists of

craniodental specimens generally well-preserved in a hard matrix but there are three postcranial bones. As a result of this discovery, a new species was described by
Kipkech

The
Lukeino Formation is believed to have been formed through continued tectonic plate activity, and it was located within a well-forested region that was located nearby to
