📖 1. Overview

Coelophysis bauri (genus Coelophysis) was a small, agile, two-legged carnivorous dinosaur that lived during the Late Triassic about 225–190 million years ago.

🦴 2. Anatomy & Morphology

Its name means "hollow form," and thanks to its hollow limb bones, its body was light and moved quickly. It had small, sharp teeth and grasping claws.

🔍 3. Fossil Record & Paleoecology

It is thought to have hunted insects and small reptiles. There was once a claim that it ate its own young, but that was dismissed when the bones inside were shown to belong to a small crocodile-relative.
