The rich material of equid fossils from Senèze is not homogeneous. Beside a few caballine teeth and limb bones (possibly cataloguing errors or intrusive specimens), there is evidence of at least two species. The bulk of the material may be referred to Allohippus senezensis, which by size and proportions is intermediate between A. pueblensis and A. mygdoniensis. One upper cheek tooth and 16 limb bones belong to a very large ?Allohippus. There are moreover a few fossils larger than the average of A. vireti of Saint-Vallier (France), and a few others as small or smaller than ?Allohippus of Pyrgos (Greece). The affinities and ages of various Pliocene and Pleistocene equid species are discussed and illustrated.
