Coelurus fragilis

† The type species of Coelurus, C. fragilis ('fragile hollow tail') was recovered from the Brushy Basin Member of the Morrison Formation in Wyoming. This Late Jurassic coelurosaur was a lightly built carnivore about 2 metres long with notably fragile, hollow post-cranial bones, sharing its ecosystem with Allosaurus, Brachiosaurus, and Stegosaurus.

Diet & Feeding

Carnivore

Coelurus fragilis was a meat-eating predator. Carnivorous dinosaurs were active hunters or scavengers, equipped with sharp teeth and claws for catching and consuming prey. They occupied the top of the food chain in their ecosystems.

Time Period

Jurassic Late Mesozoic Era

Coelurus fragilis lived during the Jurassic Late period of the Mesozoic Era, approximately 161,5 to 145,0 million years ago.

One of the most iconic periods for dinosaurs. Giant sauropods like Brachiosaurus and Diplodocus roamed alongside predators like Allosaurus. Archaeopteryx, the earliest known bird, appeared. The Morrison Formation preserves an extraordinary fossil record from this time.
