Amerhippus is an extinct subgenus of Equus which includes several species of horses that lived in South America. Fossils have been recovered from the Tarija Formation of Bolivia, the Serranía del Perijá in Venezuela, the Chiu-Chiu Formation of Chile, the Sabana Formation of the Bogotá savanna in Colombia,[2] and from various locations in Ecuador.[3] The genus was living from 2.588 to 0.012 Mya. It measured roughly 1.5 metres (4.9 ft) in height and approximately 400 kilograms (880 lb) in weight.
