Allosaurus Caudal Vertebrae - Stand Included

**Allosaurus: Colorado’s Prehistoric Powerhouse**

Allosaurus, a formidable predator of the Jurassic period, was a significant figure in the ecosystems of what is now North America, including regions like Colorado. Flourishing approximately 155 to 150 million years ago, Allosaurus was a classic large theropod dinosaur, characterized by its bipedal stance, formidable jaws, and sharp teeth. In terms of physical attributes, Allosaurus could grow up to 28 feet long and stand more than 10 feet tall. It had a large head with dozens of sharp, serrated teeth that were perfectly adapted for a carnivorous diet. Its robust and muscular body was supported by two powerful hind legs, while its shorter front limbs had three-fingered hands with sharp claws.

Colorado has been a rich source of Allosaurus fossils, particularly in the Morrison Formation, a renowned geological formation known for its abundant and diverse dinosaur fossils. The Allosaurus fossils found here have included well-preserved skulls, teeth, and various skeletal parts, providing crucial insights into the anatomy and lifestyle of these dinosaurs. These remains suggest that Allosaurus was a top predator in its habitat, preying on large herbivorous dinosaurs.
