Eucoelophysis is known from the complete research of bones gathered from the Chinle Formation. It is named based on its similarities with the coelophysid dinosaurs.

They are named Eucoelophysis which in literal terms means 'true hollow form'. It was considered to be similar to the coleophysids for a long time in history until Nesbitt suggested another explanation after his research.

It was suggested that Eucoelophysis was actually not a true dinosaur and these early dinosaurs were basal dinosauriforms of the Silesauridae family and a close relative of Silesaurus.
