Serengetilagus is a genus of lagomorph in the family Leporidae. It lived in the Pliocene of Kenya and Tanzania and the Late Miocene of Chad.[1] Serengetilagus is the best-represented taxon from Laetoli, with approximately 34 percent of fossils in the Laetolil Beds attributed to this genus. Additional specimens from Angola, Morocco[3] and the Ukraine[4] may also belong to this genus. It had a number of specific features unknown in other lagomorphs, such as a "missing" mesoflexid on its third premolar.[5]
