Equus giganteus, an extinct species of giant horse, lived during the Pleistocene era in North America. It was notable for its impressive size, standing taller than modern horses. These herbivores roamed grasslands and played a crucial role in their ecosystem by influencing vegetation patterns and serving as prey for large predators.

Equus giganteus, commonly known as the Giant Horse, is an extinct species that was native to North America. Fossil evidence suggests that it roamed regions that are now part of the United States, including areas like the Great Plains and potentially extending into what is now Mexico.

Equus giganteus inhabited open grasslands and prairie regions, which were characterized by vast expanses of grasses and few trees. These areas typically experienced a temperate climate, with seasonal variations that included cold winters and warm summers.

As a large herbivore, Equus giganteus played a crucial role in the grassland ecosystems. It likely fed on a variety of grasses and other low-lying vegetation, contributing to the maintenance of these habitats by preventing overgrowth and promoting plant diversity. Its size and grazing habits also made it an important prey species for large predators of the time.
