Beyond the game
The real Coelophysis
It had a slender body and walked on two legs. This carnivore could reach about three meters in length and belongs to one of the first stages in the history of dinosaurs.
The name Rioarribasaurus is considered a synonym of Coelophysis. Its length should not be confused with that of a wide-bodied animal: an important part corresponded to the neck and tail. The shape of the bones helps reconstruct those proportions.
This grouping describes evolutionary relationships. Its members share ancestors; they do not form a chain in which one must turn into another.
