Tyrannosaurus (/ t ɪ ˌ r æ n ə ˈ s ɔː r ə s, t aɪ-/) [a] is a genus of large theropod dinosaur.The type species Tyrannosaurus rex (rex meaning 'king' in Latin), often shortened to T. rex or colloquially T-Rex, is one of the best represented theropods.
Previously discovered T. rex skeletons were usually missing over half of their bones. [10] It was later determined that Sue was a record 90 percent complete by bulk, [11] and 73 percent complete counting the elements. [12] Of the 360 known T. rex bones, around 250 have been recovered. [1]
When the preparation was complete in 2011, a ~65% complete T. rex skeleton was revealed. [ 2 ] Since its discovery and extensive subsequent study, Scotty has been referred to as the largest T. rex ever discovered in the world, the largest of any dinosaur discovered in Canada, and as one of the oldest and most complete fossils of its kind at ...
T. rex was fully grown at around 18-21 years. Perhaps the largest-known Tyrannosaurus, a specimen named Sue at the Field Museum in Chicago, is 40-1/2 feet (12.3 meters) long.
T. rex specimen discovered by Sue Hendrickson She also met Swiss paleontologist Kirby Siber, who allowed her to join his team consisting of paleontologists Carlos Martin and Peter Larson . [ 9 ] The group began excavating Miocene baleen whale fossils at an ancient seabed in Peru, and Hendrickson joined the team for several summers, discovering ...
Skeletal mount of the Tyrannosaurus holotype.. This timeline of tyrannosaur research is a chronological listing of events in the history of paleontology focused on the tyrannosaurs, a group of predatory theropod dinosaurs that began as small, long-armed bird-like creatures with elaborate cranial ornamentation but achieved apex predator status during the Late Cretaceous as their arms shrank and ...
This sudden change in growth rate may indicate physical maturity, a hypothesis that is supported by the discovery of medullary tissue in the femur of an 18-year-old T. rex from Montana (MOR 1125, also known as "B-rex"). [51] Medullary tissue is found only in female birds during ovulation, indicating that "B-rex" was of reproductive age. [52]
Model of a dinosaur egg. Dinosaur reproduction shows correlation with archosaur physiology, with newborns hatching from eggs that were laid in nests. [1] [2] Dinosaurs did not nurture their offspring as mammals typically do, and because dinosaurs did not nurse, it is likely that most dinosaurs were capable of surviving on their own after hatching.
