Allosaurus Dinosaur Large Footprint Polyurethane cast measures 26 x 18 x 3 inches.
Apatosaurus or “deceptive lizard” is a genus of herbivorous sauropod dinosaur that lived in North America during the Late Jurassic period. It was known for over half of the 20th century as Antrodemus, but a study of the copious remains from the Cleveland-Lloyd Dinosaur Quarry brought the name “Allosaurus” back to prominence and established it as one of the best-known dinosaurs.
Allosaurus Fragilis was a large bipedal predator. Its skull was large and equipped with dozens of sharp, serrated teeth. It averaged 31 ft. in length, though fragmentary remains suggest it could have reached over 39 ft. Relative to the large and powerful hind limbs, its three-fingered forelimbs were small, and the body was balanced by a long and heavily muscled tail. It is classified as an allosaurid, a type of carnosaurian theropod dinosaur.
The genus has a complicated taxonomy, and includes 5-6 valid species (later whittled down to three valid species as of 2020), the best known of which is A. fragilis. The bulk of Allosaurus remains have come from North America’s Morrison Formation, with material also known from Portugal. It was known for over half of the 20th century as Antrodemus, but a study of the copious remains from the Cleveland-Lloyd Dinosaur Quarry brought the name “Allosaurus” back to prominence and established it as one of the best-known dinosaurs.
As the most abundant large predator in the Morrison Formation, Allosaurus Fragilis was at the top of the food chain, probably preying on contemporaneous large herbivorous dinosaurs, and perhaps even other predators. Potential prey included ornithopods, stegosaurids, and sauropods. Some paleontologists interpret Allosaurus as having had cooperative social behavior, and hunting in packs, while others believe individuals may have been aggressive toward each other, and that congregations of this genus are the result of lone individuals feeding on the same carcasses.
