ALLOSAURUS TRIVIA II

11) What was the average lifespan of an Allosaurus?


Barring disease, starvation, or thagomizer wounds inflicted by an angry Stegosaurus, Allosaurus had an estimated lifespan of up to 28 years.

12) How many species of Allosaurus have been named?


Six species of Allosaurus have been named: A. amplus, A. atrox, A. europaeus, A. fragilis, A. jimmadseni, and A. lucasi. Among these, Daniel Chure and Mark Loewen in 2020 only recognized the species A. fragilis, A. europaeus, and the newly-named A. jimmadseni as being valid species.

13) What year did Allosaurus first appear in a dinosaur movie?


The Lost World, released in 1925, was the first full-length dinosaur movie--and it starred not Tyrannosaurus Rex but Allosaurus (with guest appearances by T. rex, Pteranodon, and Brontosaurus). Less than a decade later, however, Allosaurus was relegated to second-string Hollywood status by T. Rex's convincing cameo in the 1933 blockbuster King Kong.

14) What U.S. state adopted Allosaurus as its official state fossil?


It was designated as the state fossil of Utah in 1988. Quarries in Utah, such as at Dinosaur National Monument near Vernal and the Cleveland-Lloyd Dinosaur Quarry near Price, have produced numerous exquisite specimens of Allosaurus and greatly expanded our knowledge of this Late Jurassic predator.
