Allosaurus is one of the best-known large carnivorous dinosaurs from North America and Europe. It hunted during the Jurassic, around 150 million years ago, and was the largest and most abundant predator in its ecosystem. History: Allosaurus fragilis was one of the first large meat-eating dinosaurs discovered and named in North America. Bones now regarded as probably Allosaurus remains were described in 1870 under the name of "Antrodemus", but the first definitive bones of Allosaurus were found in Cañon City, Colorado, and described in 1877 by the eminent American paleontologist, Othniel Charles Marsh of Yale University. Since then, the fossilized remains of at least 60 Allosaurus individuals have been found and described from across the USA, including some complete skeletons. Scientific Name: Allosaurus fragilis Characteristics: Allosaurus was a muscular carnivore with large jaws filled with sharp curved teeth. It had a low triangular projection above each eye.
