Basilotritus
Basilotritus is a genus of basilosaurid early whale known from the early late Middle Eocene (late Lutetian to Bartonian, ) Kiev Formation of the Ukraine, Stockletten Formation of Germany, Tongeren Formation of the Netherlands, Giushi Formation of Egypt and the United States (Castle Hayne Formation, North Carolina and Piney Point Formation, Virginia). Section::::"Basilotritus uheni". "Basilotritus uheni" has been found in the late Middle Eocene (Bartonian) Kiev Formation at Beloskelevatoye, Ukraine, making it the oldest fossil cetacean from Eastern Europe. Its holotype, NMNH-P OF-2096, consists of a partial skeleton. Section::::"Basilotritus wardi". "Basilotritus wardi" is known from a partial skeleton collected  in the late Lutetian (~42 Ma) of North Carolina. It was originally described as a species of the protocetid "Eocetus", "E. wardii". Because this species displays a mix of protocetid and basilosaurid traits, the original generic assignment was questioned by subsequent authors. This skepticism was confirmed by the discovery of "B. uheni", allowing for "E." "wardi" to be referred to "Basilotritus".
