Falcatodon
Falcatodon is a genus of hyainailourid creodont from the Early Oligocene (Rupelian) of the Fayum Depression in Egypt. Description. Morales and Pickford (2017, p. 344) diagnose "Falcatodon" as follows: "Medium sized Hyainailourinae, differing from Metapterodon by the reduction of the protocone in the upper molars (M1 – M2), which is located in a very anterior position. It differs from Hyainailouros by the more sectorial morphology of the upper molars, with more advanced fusion of the paracone-metacone with, nevertheless, a groove separating the cusps visible in the M1. Lower molars sectorial with reduced talonid and without a metaconid. It differs  from Isohyaenodon, Sectisodon and Exiguodon, by the lesser reduction of the protocone in the upper molars which, above all, retain a stretched out subtriangular occlusal outline." Taxonomy. "Falcatodon" was originally described as a new species of "Metapterodon", "M. schlosseri", by Holroyd (1999), who nonetheless recognized that Eocene and Oligocene hyainailourids he assigned to "Metapterodon" might prove generically distinct. Subsequent study demonstrated that "Falcatodon" is not only distinct from "Metapterodon" but also closely related to "Isohyaenodon".
