Coelophysis

Coelophysis bauri is the earliest dinosaur known from a number of complete fossil skeletons. C. bauri was a lightly built dinosaur which measured up to three meters in length and which was than a meter tall at the hips. The name Coelophysis means "hollow form" or "hollow process", so named because of its hollow limb bones.

Coelophysis was very slim and it probably would have been a fast runner. Despite being an early dinosaur, the evolution of the theropod body form had already advanced greatly from creatures like Herrerasaurus and Eoraptor. Coelophysis ate fish, small reptiles, and sometimes each other (if evidence is correct).

In Jurassic Park
Coelophysis was featured in the Game-Boy Advanced game Jurassic Park III: Park Builder. Coelophysis appeared in JP toy series 1 toy line,it came with constrictor bodies and comes with 2,perhaps to do like the real Coelophysis hunting in packs.
