Sue, the largest and most complete (90%) Tyrannosaurus rex skeleton yet discovered On May 17, 2000, the Field Museum unveiled Sue , the largest T. rex specimen discovered at the time. Sue has a length of 40.5 feet (12.3 m), stands 13 feet (4.0 m) tall at the hips, and has been estimated at 8.4–14 metric tons (9.26–15.4 short tons ) as of 2018.
Physiology of dinosaurs. The physiology of dinosaurs has historically been a controversial subject, particularly their thermoregulation. Recently, many new lines of evidence have been brought to bear on dinosaur physiology generally, including not only metabolic systems and thermoregulation, but on respiratory and cardiovascular systems as well.

The largest known bird of prey ever was the enormous Haast's eagle (Hieraaetus moorei), with a wingspan of 2.6 to 3 m (8 ft 6 in to 9 ft 10 in), relatively short for their size. [519][520] Total length was probably up to 1.4 m (4 ft 7 in) in female [521] and they weighed about 10 to 15 kg (22 to 33 lb). [522]
Mounted skeletons of Tyrannosaurus (left) and Apatosaurus (right) at the AMNH. Dinosaurs are a diverse group of reptiles of the clade Dinosauria. They first appeared during the Triassic period, between 243 and 233.23 million years ago, although the exact origin and timing of the evolution of dinosaurs is the subject of active research.
Tyrannosaurus equals Edmontosaurus in U3 and in L3 comprises a greater percentage of the large dinosaur fauna as the second-most abundant taxon after Triceratops, followed by Edmontosaurus. This is surprisingly consistent in (1) the two major lag deposits (MOR loc. HC-530 and HC-312) in the Apex sandstone and Jen-rex sand where individual bones ...
Allosaurus (/ ˌæləˈsɔːrəs /) [2][3] is an extinct genus of large carnosaurian theropod dinosaur that lived 155 to 145 million years ago during the Late Jurassic period (Kimmeridgian to late Tithonian ages). The name " Allosaurus " means "different lizard", alluding to its unique (at the time of its discovery) concave vertebrae.
