Allosaurus Facts for KidsAllosaurus Facts for Kids

Check out our cool Allosaurus facts for kids. The Allosaurus was a large dinosaur that lived around 150 million years ago. It was a carnivore with big, sharp teeth and there is even evidence to suggest that it attacked the much heavier Stegosaurus.

Read on to find out more interesting information about what the Allosaurus looked like, where its fossils have been found, what its name means and much more.

 


  • Allosaurus lived around 150 million years ago in the late Jurassic Period.

  • The name Allosaurus means ‘different lizard’.

  • Allosaurus was first described by Othniel Marsh in 1877 and become one of the first well known dinosaurs. Marsh also named and gave the first description of the Apatosaurus (Brontosaurus) in that same year.

  • Most Allosaurus fossils have been found in the Morrison Formation, a distinctive band of sedimentary rock found in the western United States.

  • Allosaurus had a large skull and walked on two legs.

  • Its body and head were balanced by a long and heavy tail.

  • Like the Tyrannosaurs rex, the Allosaurus had short arms. It had three fingers that were each tipped with sharp, curved claws.

  • Research suggests that the average length of an Allosaurus was around 8.5 metres (28 feet) and that it weighed around 2.3 tons.

  • Allosaurus was a carnivore (meat eater) and featured big, sharp teeth that had edges like saws. They were active predators and there is evidence that they attacked Stegosaurus.

  • In 1991 a 95% complete skeleton of an Allosaurus was found in Wyoming, United States. Nicknamed ‘Big Al’, the Allosaurus skeleton (along with a further skeleton nicknamed ‘Big Al Two’) greatly helped scientists further the study of Allosaurus.

  • The Allosaurus is a popular dinosaur that has featured in many books, documentaries and films, including Arthur Conan Doyle’s 1912 book ‘The Lost World’ and the BBC television series called ‘Walking with Dinosaurs’.
