Widanelfarasia is an extinct genus of placental mammals known from the Late Eocene Jebel Qatrani Formation of Egypt. Two species are known: W. bowni and the smaller W. rasmusseni. Described in 2000 by E. R. Seiffert and Elwyn L. Simons, Widanelfarasia was initially classified as uncertain position ( incertae sedis ) within placentals,^[1] but was later placed within the afrosoricidan suborder Tenrecomorpha (tenrecs and otter shrews).^[2]^[3] The genus name derives from Widan el-Faras (Arabic for "Ears of the Mare"), two prominent hills in the area where the fossils were recovered.^[1]
