The Meshippus is the same as the Miohippus and they had long legs to make them faster. So i don't think they were eaten by predators maybe but i don't know which kind of them.
The eohippus, an early ancestor of the modern horse, is believed to have been a herbivore, likely feeding on a diet of leaves, fruits, and other plant matter. Its small size and primitive teeth suggest it may have primarily eaten soft vegetation.

the EOHIPPUS lived in Asia and north America

Natural selection likely favored individuals of Eohippus that were better adapted to their environment, such as those with longer limbs for faster running to evade predators or with teeth suited for browsing on tough vegetation. Over time, these advantageous traits became more common in the population while less beneficial traits were minimized, leading to the evolution of the species.
The Eohippus lived in the early Tertiary Period and the early to mid eocene Epoch, about 55-45 million years ago.Answers.com
