What is the natural predators of a pliohippus?

Pliohippus, an extinct genus of horse that lived during the Miocene epoch, likely had various natural predators, including large carnivorous mammals such as saber-toothed cats and large canids. Other potential threats could have included large Birds of Prey and predatory reptiles that coexisted in its environment. However, due to its size and speed, Pliohippus may have had fewer natural predators compared to smaller herbivores. Its adaptations for running would have also helped it evade many predators.
