T Rex Size report

t rex modelTyrannosaurus rex lived in the Maastricht period at the end of the Cretaceous period, which is the last Cretaceous period about 68.5 to 65 million years ago. Tyrannosaurus Rex fossils are distributed in North America, Canada, the United States. It is considered to be one of the last dinosaurs to be extinct.

In 1902, Barnum Brown, an American dinosaur fossil collector, discovered a giant carnivorous animal skeleton in Hale Creek, Montana, USA. What he found were the bones of the first Tyrannosaurus rex. On December 25, 2013, British and Australian researchers said that a Tyrannosaurus rex pubic bone fossil was found in Australia; evidence shows that Tyrannosaurus rex also lived on the southern hemisphere continent.

Humans know very little about Tyrannosaurus rex, but as more dinosaur fossils are unearthed year by year, people better understand their living habits, body parts, size, etc., and make more reliable speculations about different historical periods. The following article explains more interesting facts about T Rex.

T Rex Basics

With the popularity of the "Jurassic Park" franchise and a renowned exhibit at the American Museum of Natural History in New York City, among other pop culture moments, T. rex maintains a reputation as the king of the dinosaurs. In 1905, Henry Fairfield Osborn, president of the American Museum of Natural History, officially dubbed the species Tyrannosaurus rex.

T. Rex was one of the biggest carnivores (meat-eating dinosaurs), but not the biggest. Giganotosaurus, Spinosaurus, and Carcharodontosaurus were bigger. They lived about 65 to 70 million years ago - in the late cretaceous period. Tyrannosaurus Rex had powerful back legs that let it hunt prey over short distances at up to 20mph (32 kph), and their flexible neck helped them adjust the angle of attack.

Judging from the skull of Tyrannosaurus rex, its teeth are cone-shaped, suitable for breaking bones, while most of the teeth of carnivorous dinosaurs are primarily used for piercing and cutting. Its skull structure shows that the hunting behavior of Tyrannosaurus rex may be different from that of most dinosaurs. Tyrannosaurus rex has very small forelimbs, which are only 22% of the hind limbs, and the length of an average individual is only about 80 cm. Tyrannosaurus rex was at the top of the food chain in the late Cretaceous period, when all kinds of dinosaurs in North America could become prey.

T Rex Size Description

Dinosaurs grow slowly throughout their lives, just like other reptiles. The largest and longest-lived Tyrannosaurus Rex "Sue" discovered has only lived 28 years old. According to scientists' research on Tyrannosaurus rex fossils and skeletons, the growth cycle of Tyrannosaurus rex ends at 19 years old and will not exceed 21 years old at the latest. When the growth cycle of Tyrannosaurus rex ends, Tyrannosaurus rex will continue to grow, and its skeleton will become stronger. Paleontologists at Florida State University discovered in the study of Tyrannosaurus rex fossils that Tyrannosaurus rex has a rapid growth period. The growth rate is quite high, and it can grow almost 4 patties of meat every day. This violent growth allows Tyrannosaurus rex to grow a huge body in a short period.

T Rex Average Sizes

A team of paleontologists confirmed that the dinosaur fossil discovered in western Canada in 1991 is the largest Tyrannosaurus Rex ever discovered in the world. The Canadian University of Alberta team stated that the Tyrannosaurus rex named "Scotty" was 13 meters long and weighed more than 8,800 kg, surpassing all carnivorous dinosaurs found in the past. On May 18, 2019, the skeleton of the world's largest Tyrannosaurus Rex "Scottie," was exhibited in Saskatchewan, Canada.

  • T. rex had strong thighs and a powerful tail, which counterbalanced its large head (Sue's skull is 5 feet, or 1.5 m, long) and allowed it to move quickly.
  • A 2011 study, which also modeled T. rex's muscle distribution and center of mass, suggests the giant could run 10 to 25 mph (17 to 40 km/h), as previous studies had estimated.

After being named in 1905, Tyrannosaurus rex has become the most widely known dinosaur. It is also the only dinosaur that is often called by the full name "Tyrannosaurus. rex", and the abbreviation of the scientific name "T.rex" is also often used.
