Resumen:
The diet and habitat for two Pleistocene Equidae genera that lived in
southern North America (southern USA and Mexico) and South America are
inferred using carbon and oxygen isotopic data. The South American
Hippidion fed upon C-3 plants and lived in forest. Equus from both
subcontinents were mixed feeders and preferred living in grasslands,
prairies, and savannas, while some individuals or populations
specialised in consumption of C-3 or C-4 plants. These results indicate
that Equus were generalist in their diet and habitat, while Hippidion
were specialists on both traits.
