It’s one of the first things visitors see when they enter the Academy of Natural Sciences: measuring up to 42 feet in length and weighing in at an estimated 7.5 tons, Tyrannosaurus rex was one of the largest predators to ever walk the Earth.
This impressive animal is one of many dinosaurs and other Mesozoic creatures you’ll encounter in Dinosaur Hall. More than 30 species are represented, about half of which are full skeletal mounts, including Avaceratops, Chasmosaurus, Corythosaurus, Deinonychus, Pachycephalosaurus, Tenontosaurus, and Tylosaurus.
In addition to the skeletons, visitors can view dinosaur eggs, footprints, sculptures, murals, paleontologist tools, a life-size model showing the internal anatomy of a Stegosaurus, and a green-screen video studio where they can project their own images into a world full of dinosaurs.
