Ptolemaiida

Ptolemaiida is a taxon of wolf-sized afrothere mammals that lived in northern and eastern Africa during the Paleogene. The oldest fossils are from the latest Eocene strata of the Jebel Qatrani Formation, near the Fayum oasis in Egypt. A tooth is known from an Oligocene-aged stratum in Angola, and Miocene specimens (of Kelba) are known from Kenya and Uganda.

The genus and type species, P. lyonsi, was described by Henry Fairfield Osborn in 1908 from the Jebel Qatrani Formation of Egypts' Fayum Depression. The genus name alludes to the Ptolemaic dynasty of Ancient Greece which ruled over the Egyptian region where Ptolemaia was discovered, while the specific epithet lyonsi honors H. G. Lyons, then director of the Egyptian Geological Survey. A second species, P. grangeri, was described in 1987, and named after the early 20th century paleo

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 & Philip Gingerich in 1974, the generic name is a combination of Qarun, the Arabic term for Lake Moeris, and -avus, Latin for "ancestor". The specific epithet honours Grant E. Mayer of the Yale Peabody Museum.
