The diet and habitat of 47 horse individuals belonging to the genus Equus from eight Mexican localities of Late Pleistocene age were determined using δ13 C and δ18 O values of their apatite carbonate. The δ13 C values indicated that, on average, these animals were C3 /C4 mixed feeders. Some individuals, however, only ate C4 plants. Some the C3 /C4 mixed feeders had significant consumption of C3 plants independent of the altitude, latitude and longitude where they were living. The type of habitat inferred was an open zone with some degree of tree coverage. These results indicated that this genus in the Mexican Pleistocene was more generalist in its diet and habitat than previously suspected.
