Horse

Equus is the modern horse genus, whose high-crowned, enamel-folded teeth are among the commonest Pleistocene mammal fossils from Florida rivers, Texas gravels and Rancho La Brea. Fossil horse teeth are inexpensive and identifiable by the enamel pattern on the chewing surface; complete jaws are affordable display pieces. Earlier horses (Nannippus, Neohipparion) from the Bone Valley Miocene are three-toed and smaller.
