The fearsome Allosaurus dinosaur skeleton is on display at the museum. Its massive skull and sharp teeth are a testament to its power. The Allosaurus was a bipedal predator that stood 30 feet tall and weighed over a ton. It lived during the Late Jurassic period, about 150 million years ago. The Allosaurus was one of the top predators of its time and is thought to have fed on other dinosaurs, such as the Stegosaurus and Triceratops.
