Equus semplicatus, was a Pleistocene species of New World stilt-legged horse,[1] and considered the type species for the stilt legged horses, one of three lineages of equids within the Americas,[2] the other two being hippidionid and caballine horses.[3] Now extinct, Equus semiplicatus once inhabited North America.[4]

Fossils found William's Cave in Texas have been identified as Equus semiplicatus.[4]
