Brown also discovered the first complete skull of Tyrannosaurus rex, part of another specimen ( AMNH 5027) located in Montana in 1907. īoth of these specimens, as well as the hindlimbs of a third specimen ( AMNH 5881), were collected by Barnum Brown, assistant curator of the American Museum of Natural History and a famous paleontologist in his own right. Had it not been for page order, Dynamosaurus would have become the official name. Because the name Tyrannosaurus rex had appeared just one page earlier than Dynamosaurus in Osborn's 1905 work, it was considered the older name and has been used since. In 1906, after further preparation and examination, Henry Fairfield Osborn recognized both skeletons as belonging to the same species. At the time of their initial description and naming, these specimens had not been fully prepared and the type specimen of T.
Another specimen ( AMNH 5866), found in Wyoming in 1900, was described in the same paper under the name Dynamosaurus imperiosus. state of Montana in 1902 and excavated over the next three years. The holotype of Tyrannosaurus rex, a partial skull and skeleton originally called AMNH 973 (AMNH stands for American Museum of Natural History), was discovered in the U.S. Tyrannosaurus rex discoveries are restricted to North America. In Montana in 1902, Barnum Brown dug up the four-foot-long femur of the first Tyrannosaurus rex found.
rex was as long as a city bus and stood at 15- to 20-feet-tall. The skull inside the plaster jacket is about 4-feet-long by 3-feet-wide. This skull size is average for an adult T.We know the Tufts-Love Rex lived at the very end of the Cretaceous because it was found at the bottom of a hill a rock layer at the top of that hill marks the Cretaceous-Paleogene mass extinction. rex lived at the end of the Cretaceous Period (145–66 million years ago) and became extinct during the Cretaceous-Paleogene mass extinction (66 million years ago). The Tufts-Love Rex is 66.3 million years old.
We’re calling it the “Tufts-Love Rex” after Luke Tufts and Jason Love, the two Burke Museum paleontology volunteers who discovered it. Next summer, Burke paleontologists will search for additional parts of the dinosaur at the site.Įach new discovery creates a fuller picture of what life on Earth was like millions of years ago and provides us greater opportunity to understand what life will be like in the future. rex grew and to what size, whether they were active predators or scavengers, and more. For instance, this specimen can give us a greater understanding of how T. Researchers can learn a lot from the Tufts-Love Rex. rex-nicknamed “Tufts-Love Rex” in honor of the two volunteers who discovered it-is just the beginning of what’s to come for this scientifically valuable specimen.
This incredible, month-long, team effort to excavate this T. rex fossils arrived at the Burke on Thursday, August 18, and were offloaded from the truck with the help of the Skanska crew (the New Burke Museum general contractor) and one of their forklifts. The skull was loaded on the flatbed truck along with ribs, the lower jaw and several other fossils for the trip to the Burke Museum.
