Species: E.‭ ‬baldwini‭ (‬type‭)‬.

Time period: Norian to Rhaetian of the‭ ‬Triassic.
Fossil representation: Partial remains of at least two individuals.

       Eucoelophysis was initially named upon the basis of a proposed similarity to coelophysid dinosaurs like Coelophysis,‭ ‬hence the name Eucoelophysis which means‭ ‘‬true hollow form‭’‬.‭ ‬However a later study by Nesbitt,‭ ‬Irmis and Parker revealed that Eucoelophysis is not a true dinosaur like Coelophysis,‭ ‬but rather a more primitive dinosauriform similar to Silesaurus.
