Qarunavus is an extinct genus of mammals in the order Ptolemaiida. A single species, Qarunavus meyeri is known from the Lower Oligocene Jebel Qatrani Formation of modern-day Egypt. Described by Elwyn Simons &amp; Philip Gingerich in 1974, the genus name is a combination of "Qarun", the Arabic term for Lake Moeris, and -"avus", Latin for "ancestor". The specific epithet honors Grant E. Mayer of the Yale Peabody Museum.
