The first Allosaurus was discovered in 1877 in Colorado and named by Othniel Charles Marsh. This specimen offered just a few fragments of the dinosaur.
In 1869, Dr. Ferdinand Vandeveer Hayden obtained a second hand fossil of an Allosaurus vertabrae that had come from Colorado. He sent it to Joseph Leidy, who in turn assigned it to the new genus Antrodemus. It is now known that this was an Allosaurus fossil. In 1877, Othniel Charles Marsh found some fragmentary remains of Allosaurus, which he then named Allosaurus fragilis.
