Eucoelophysis (meaning “true hollow form”) is a genus of silesaurid dinosauriform from the Late Triassic (Norian) period Chinle Formation of New Mexico. It was assumed to be a coelophysid upon description, but a study by Nesbitt et al. found that it was actually a close relative of Silesaurus, which was independently supported by Ezcurra (2016), who found it to be the sister group to Dinosauria, and Silesaurus as the next most basal taxon.
