Existing in the late Triassic period, the ceolophysis were a small and agile carnivorous dinosaur that lived on small reptiles and insects. They had hollow limb bones, making them extremely light, and sharp teeth and short claws that would have helped them to hold their prey down, as well as a double hinged jaw which would have acting as a saw when eating food.
The ceolophysis lived between 225 and 220 million years ago, with the early fossils discovered in America in 1889. The best example of this dinosaur’s preserved skeleton was discovered in Ghost Ranch, New Mexico in 1947. A group of ceolophysis are all believed to have died of thirst before a flash flood buried their remains.
