Equus Scotti

Equus scotti (translated from Latin as Scott's horse, named after vertebrate paleontologist William Berryman Scott) is an extinct species of Equus, the genus that includes the horse. E. scotti was native to North America and likely evolved from earlier, more zebra-like North American equids early in the Pleistocene Epoch. The species may have crossed from North America to Eurasia over the Bering land bridge during the Pleistocene. The species died out at the end of the last ice age in the large-scale Pleistocene extinction of megafauna.

It was among the last of the native horse species in the Americas until the reintroduction of the horse approximately 10,000 years later, when conquistadors brought modern horses to North and South America circa 16th century, some of which later escaped to the wild and became ancestors of the many feral horses living today in the Americas.
