The most powerful Tyrannosaurus rex a record is the legend of the name Scotty, who – during his life on Earth about 65 million years ago – weighs 19,555 lbs. (8,870 kilograms), or about 6.5 Volkswagen Beetles, a new study finds.
Scotty was so immense, he went out Sue, the famous T. rex at the Natural History Field Museum in Chicago, as a heavyweight champion.
Scotty is generally about 880lb. (400 kg) is heavier than Sue, "that's a lot according to human standards, but not so much when you're dealing with thyrannosaur," said lead researcher of the study, Scott Person, a palaeontologist at Alberta University. [Gory Guts: Photos of a T. Rex Autopsy]
Scotty researchers originally found in 1991, near the town of Eastend, Saskatchewan. But it took years to dig and then prepare the king of dinosaurs, because the rock in which the fossils were incorporated was a "hard piece of pieces", "People of Living Living". That sandstone – heavily cemented, rich in iron – was part of the French Cretaceous Formation, dating from the late Cretaceous period, from around 72 million to 65 million t years ago.
T. rexeshowever, only about 2 million of the last Cretaceous years, or from about 67 million to 65 million years ago.
The researchers loved the discovery, they celebrated it with toast. "The only spirit that was on hand was on an old bottle of squot," people said, who inspired them to name the T. rex Scotty. However, it is unclear whether Scotty was male or female, People identified.
After all the Scotty fossils were prepared, researchers found that they had about 65 per cent of the skeleton, including the skull, the frenzy (the part of the skull that holds the brain). ; the lower jaw; vertebra of the neck, the back and the tail; and parts of the hips, the leg and the shoulder.
However, Scotty is not the heaviest dinosaur recorded. That honor is likely to go to the old tribe Argentinosaurus, which may have weighed up to 110 tonnes (100 tonnes), according to some estimates. (The sport of determining the mass of dinosaurs is a very controversial subject, as there are different ways of calculating it. In this case, scientists decided on Scotty's prestige by comparing the proportion of his bones and plugging the measurements. this formula, Persons.
Moreover, while Scotty is the heaviest T. rex on record, it is not the longest. A T. rex Stan's name, which is exhibited at the Black Hills Geological Research Institute, which spans almost 40 feet (12.2m) from tail diversion. In addition, the most complete is known T. rex Sue is still, which is about 90 percent complete.
But Scotty has other claims for fame. For example, it's probably his 30th birthday, making him the longest running one t T. rex according to bone analysis by co-investigator Gregory Erickson, professor of anatomy and spinal paleobiology at Florida State University. Erickson did this by looking at the growth cycles in the dinosaur bones (like trees, dinosaur bones set new circles as they got older).
Scotty's bones also kept the dinosaur dramatic injuries, all of which had improved by the time the dinosaur died. These contained chopped chin, broken ribs and a series of pressed vertebrates that Scotty carried out during his "violent and unusually long life," wrote the researchers in the study.
It was added that the "relative shortage of T. rex specimens so large and other mature" suggests that these monsters tend to die before they pass the 8.8-tonne threshold (8 tonnes).
Scotty will be on public display at the Royal Saskatchewan Museum in Regina, Saskatchewan, in May. The online study was published on 21 March in The Anatomical Record magazine.
