''Fruitachampsa'' is a genus of shartegosuchid crocodyliform from the Upper Jurassic Morrison Formation of Colorado. It is known from multiple specimens that show it to have been a relatively long-limbed terrestrial quadrupedal predator less than long, with a short face and a prominent pair of canine-like teeth in the lower jaw. Before it was formally described in 2011, it was also known as the "Fruita form". Its type species is ''F. callisoni''. ==Discovery== Fossils of ''Fruitachampsa'' have been found from the Fruita Paleontological Area (FPA) in Fruita, Colorado. The deposits in the FPA belong to the Morrison Formation, which is Late Jurassic in age. The first remains of ''Fruitachampsa'' were found by paleontologists James Clark and George Callison in 1975, who discovered a diverse assemblage of microvertebrates at the FPA. More complete material of ''Fruitachampsa'' was found in 1976, 1977, and 1979. ''Fruitachampsa'' has been found alongside another more primitive crocodylomorph, ''Macelognathus''.〔 The name ''Fruitachampsa'' has existed since the late 1980s. Because the name was not published with a formal description, ''Fruitachampsa'' was considered a ''nomen nudum'' or "naked name." ''Fruitachampsa callisoni'' was formally described by James Clark in 2011, with the specific name honoring George Callison.〔
