The very first Tyrannosaurus was found by the famous fossil collector, Barnum Brown in 1900 in Wyoming. Over the next five years, he collected four more skeletons, and Henry Osborn, from the American Museum of Natural History in New York studied these skeletons and named Tyrannosaurus rex in 1905. The largest of Brown’s skeletons can be seen on display At the American Museum, and another is on display at the Cleveland Museum of Natural History.

In real life, Tyrannosaurus, was large (at least 40 feet long), stout and muscular (5-6 metric tons), but our Tyrannosaurus Rex figure is much smaller. It ran on its thick hind legs. Its huge jaws contained lots of sharp, six inch long teeth. Each tooth had a serrated blade on both the front and back edges that could easily have cut through any prey. Its front limbs were tiny and its hands had only two little fingers. We don’t know what these fingers were for, but they were far too small and weak to walk on, fight off other dinosaurs, or grasp prey.
