![]() rex forms the centrepiece of the Animal World, a spectacular array of creatures from the past and the present day, including a great white shark, a hippo and a Triceratops skull, among many others. rex specimens in the world, which is held in the Museum of the Rockies.Ībove: Part of the T.rex cast skeleton being installed at National Museum of Scotland. The cast has been taken from one of the most complete T. rex brings people as close as possible to appreciate the scale and power of the real thing. rex actually walked the earth, but our T. living dinosaurs).It is 65 million years since T. From there, our scientists worked with an animation team in the UK to give life to SUE’s mechanics, referencing crocodilians and large modern-day birds (a.k.a. rex research, we estimate SUE’s top speed to be a fast walk of 15 miles per hour. Using the 3D digital model of SUE and new size estimates, paired with other T. rex’s speed is limited by its body mass and how much leg muscle is required to keep the knee erect under the force of the animal’s mass at full speed. rex and humans included, walking and running requires putting all your body mass on one leg for a very brief moment. rex move, and how do we know? It’s a combination of what SUE’s bones tell us and what we can observe in living animals. rex-still fierce, but not exactly the roaring, crashing creature from Jurassic Park. Realistic animations of SUE walking, hunting, and drinking from a nearby river will give you a totally new perspective on T. rex moved and looked in life during the Late Cretaceous. SUE’s gallery in the Griffin Halls of Evolving Planet also gives you a sense of how T. rex was even bigger than we thought, likely weighing nine or ten tons. But after 3D scanning every one of SUE’s bones and creating a digital model of the whole skeleton, scientists could do a 3D estimation of mass-this time determining that T. Previously, scientists measured leg bone circumference to determine body mass, which led to estimates of five to seven tons. The gastralia also enhance information about T. Now, they look as though they could actually touch each other. This lowered SUE’s arms and brought them forward a bit. We also corrected SUE’s furcula-or wishbone, much like in your Thanksgiving turkey-and adjusted the shoulder blades. Curator of Dinosaurs Pete Makovicky gave us a rundown of some of the changes that give SUE a new look.Īdding the gastralia, with the first pair stretching 44 inches apart at the tips, meant adjusting other elements of the skeleton, including making the ribs wider. Now, SUE’s updated skeleton and new gallery bring to life the latest on what we know about T. ![]() rex ’s arms are tiny learn what caused the holes in SUE’s jaw and get a more accurate idea of how long SUE lived (28–33 years). SUE presented a unique opportunity to study many different bones that all belong to the same animal-a thrill for paleontologists.Īs Field scientists and visiting researchers ask new questions and examine different parts of SUE’s skeleton, we keep honing in on a more complete picture of T. But this didn’t mean scientists’ work was done in a lot of ways, it was just getting started. SUE arrived here at the Field in 1997 and was unveiled in 2000, wowing the world as the largest, most complete Tyrannosaurus rex specimen discovered. rex’s fossils are a snapshot of life 67 million years ago, the science around extinct animals is rarely set in stone. Get an in-depth look at SUE's scientific updates and new home in the Griffin Halls of Evolving Planet.
