This contrasts sharply with the size of Cenozoic mammals, estimated by the National Museum of Natural History as about 2 to 5 kg (4.4 to 11.0 lb). The mode of Mesozoic dinosaur body masses is between one and ten metric tonnes. Predatory theropod dinosaurs, which occupied most terrestrial carnivore niches during the Mesozoic, most often fall into the 100–1,000 kg (220–2,200 lb) category when sorted by estimated weight into categories based on order of magnitude, whereas recent predatory carnivoran mammals peak in the range of 10–100 kg (22–220 lb). The latest evidence suggests that dinosaurs' average size varied through the Triassic, early Jurassic, late Jurassic and Cretaceous periods, and dinosaurs probably only became widespread during the early or mid Jurassic. Dinosaurs show some of the most extreme variations in size of any land animal group, ranging from tiny hummingbirds, which can weigh as little as two grams, to the extinct titanosaurs, which could weigh as much as 50–100 t (55–110 short tons). ![]() Size is an important aspect of dinosaur paleontology, of interest to both the general public and professional scientists.

The specific problem is: Outdated information and unreliable overestimates. The skeleton, which is about 65 percent complete, is scheduled to go on display in May at the Royal Saskatchewan Museum.This article may require cleanup to meet Wikipedia's quality standards. Scotty’s bones bear the scars of numerous injuries including a broken rib, an infected jaw and a bite that appears to be from another T. “By Tyrannosaurus standards, it had an unusually long life. “You can get an idea of how old a dinosaur is by cutting into its bones and studying its growth patterns. rexes grew fast and died young, making Scotty the oldest of its kind. Scotty died at around 28 years old in Saskatchewan about 66 million years ago, the study says. Galleonosaurus: Wallaby-sized dinosaur was sprinting around Australia 125 million years ago, jaw fossil report suggests Under the sea: A 'sea monster' from 500 million years ago: Scientists say this creature had 18 tentacles Although the bones were found in 1991, it took more than a decade to excavate them from the surrounding hard sandstone. The fossil was nicknamed after a celebratory bottle of scotch opened the night it was discovered in Canada. Some individuals were lankier than others and some were more robust. ![]() “There is considerable size variability among Tyrannosaurus. “This is the rex of rexes,” said study author W. rex ever found, it’s also larger than all other carnivorous dinosaurs. Not only is the massive specimen the biggest T. The massive predator, nicknamed “Scotty,” was about 42 feet long and likely weighed more than 9.7 tons, according to the study published last week in the peer-reviewed journal The Anatomical Record. Paleontologists have unearthed the largest Tyrannosaurus rex fossil ever discovered, researchers say. ![]()
