The giant horse (Equus giganteus) is an extinct species of horse which lived in North America.
It was classified as a species based on the finding of a single tooth larger than the teeth of even the largest modern draft horses.[1][2] Based on the tooth, the weight was estimated at 1,200–1,500 kg (2,600–3,300 lb) and the height at 2.25 m (7 ft 5 in) tall at the shoulder.[3] Because it is based on fragmentary remains, recent authors have considered the species to be an invalid nomen dubium.[4]
