Navahopus is an ichnogenus of dinosaur footprint that was made by an indeterminate navahopodid sauropodomorph once thought to have been a prosauropod that was alive during the Early Jurassic in southwestern United States. Two ichnospecies are known: the type ichnospecies, N. falcipollex (named in 1980[1]) and a second species, N. coyoteensis (named in 2008[2]). It is known from the Early Jurassic of Arizona (Aztec Sandstone and Navajo Sandstone), California (Aztec Sandstone) and Utah.[3]
