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 ...
A rare fossil discovery marks the first time a tyrannosaur’s stomach contents have been found, a new study says. The young apex predator was a cousin of T. rex.
Tyrannosaurus was named by Henry Fairfield Osborn in 1905, along with the family Tyrannosauridae. [15] The name is derived from the Ancient Greek words τυραννος tyrannos ('tyrant') and σαυρος sauros ('lizard'). The superfamily name Tyrannosauroidea was first published in a 1964 paper by the British paleontologist Alick Walker. [16]
When T. rex was first discovered, the humerus was the only element of the forelimb known. [6] For the initial mounted skeleton as seen by the public in 1915, Osborn substituted longer, three-fingered forelimbs like those of Allosaurus. [4] A year earlier, Lawrence Lambe described the short, two-fingered forelimbs of the closely related ...
Dinosaur teeth found with the help of a retired quarry worker have revealed how the fearsome tyrannosaur once roamed Bexhill-on-Sea. Research led by the University of Southampton found that ...
The embryo belongs to an oviraptorid theropod dinosaur, and the egg is classified as elongatoolithid. The specimen has been described as one of the best dinosaur embryos ever found. [ 1 ] The specimen represents a late-stage embryonic individual preserved in a position similar to extant birds, and is the first example of this to be found in a ...
A partial skull once believed to be from a T. rex is a newfound species, a study revealed. T. mcraeensis could shed light on why tyrannosaurs evolved into giants.
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.
