Extinct equids restored to scale. Left to right: Mesohippus, Neohipparion, Eohippus, Equus scotti and Hypohippus. Wild horses have been known since prehistory from central Asia to Europe, with domestic horses and other equids being distributed more widely in the Old World, but no horses or equids of any type were found in the New World when European explorers reached the Americas.
Mesohippus (Greek: μεσο / meso meaning "middle" and ιππος / hippos meaning "horse") is an extinct genus of early horse. It lived 37 to 32 million years ago in the Early Oligocene. [1] [2] Like many fossil horses, Mesohippus was common in North America. Its shoulder height is estimated at 60 cm. [3]
The possible causes of the extinction of horses in the Americas (about 12,000 years ago) have been a matter of debate. Hypotheses include climatic change and overexploitation by newly arrived humans. [22] [23] Horses only returned to the American mainland with the arrival of the conquistadores in 1519. [24]

The proportion of extinct large mammal species (more than or equal to 10 kg (22 lb)) in each country during the last 132,000 years, only counting extinctions earlier than 1000 years BP. The Late Pleistocene saw the extinction of many mammals weighing more than 40 kilograms (88 lb), including around 80% of mammals over 1 tonne.

Equus lambei, commonly known as the Yukon horse or Yukon wild horse, [1] [2] is an extinct species of the genus Equus. Equus lambei ranged across North America until approximately 10,000 years ago. Based on recent examinations of the mtDNA of Equus lambei remains, scientists have concluded that E. lambei was probably much like the extinct ...
