There were Caballine
horses, Cerbat mustangs, Sulphurs, Curlies and Kigers feeding on rolling green pastures.
excelsus was a medium-sized horse and that the larger caballine
horses of the late Pleistocene may have been E.
Originally described as a member of the genus Asinus, Equus lambei is now assigned to the caballine
group on the basis of physical traits described by Harington (1989) and Forsten (1988) and multivariate analyses carried out by Eisenmann (1980, 1986; Burke and Cinq-Mars, 1996).
The pattern of shallow ectoflexid and U-shaped linguaflexid seems to be consistent in the caballine group.
Many European paleontologists (cited above) accept the shape of the linguaflexid of the lower molar as a major character separating caballine (domestic horse type) from the zebrine (stenonine) horses.
At Slaton eight (73 percent) of the jaws show the caballine horse pattern (shallow ectoflexid, U-shaped linguaflexid) (Fig.
At the Slaton Quarry all horses except the stilt-legged Equus calobatus seem to be caballine.
