Dinosaurs like Coelophysis, a highly adaptable little carnivorous dinosaur that was both an active hunter and a scavenger, can survive on very little water. Probably solitary most of the time, but during the dry season would occasionally concentrate in large groups around food and water resources. They are also light boned, fast, and they are beautifully adapted for killing.

Coelophysis ("Hollow Form") is a 3-meter long theropod dinosaur that lived during the Late Triassic period. One of the very first and earliest known genera of dinosaurs ever to evolve, Coelophysis was a relatively small, carnivorous theropod of the Triassic - though for its time it was actually a fairly sizeable theropod. Due to its sleek appearance and bone structure, its name means, 'Hollow Form'. It was about 2 metres long, and had a notably lightweight and yet lithe body.



As some of the very first dinosaurs, Coelophysis lived during the Late Triassic period 225-208 million years ago. It has been known to be one of the earliest species of dinosaurs that ever evolved.


Coelophysis was small but it was just as big as a man, standing 3-5 feet tall, 9-10 feet long, and weighing less than 100 lbs. They can survive on very little water and are also light-boned, fast, and beautifully adapted for killing.

They first appeared around 230 million years ago. But what made them unique were special hips and ankles that allowed them to stand perfectly balanced on two legs. With lightning fast reactions, they were built to survive. To these swift predators, Placerias were prey. It was their speed and agility that gave them the edge in the Mid-Triassic.

Behavior Edit

Though Coelophysis was a pack-hunter, allowing it to hunt other animals, during a dry season when food was scares, their numbers were on the increase, this led to confrontations. They were opportunistic feeders and would eat anything that moves. Coelophysis was built to be a slender, agile reptile with long neck and tail, perfect for searching scorpions, lizards, and other small animals that may be hiding under rocks, in holes, or on trees.
