Baby T. Rex was an adorable ball of Fluff

It may be difficult to imagine the tower Tyrannosaurus rex as small, but the toothy Cretaceous giant was not born from an egg fully grown. In fact, T. rex hatchlings were about the size of very lean turkeys, with "arms" longer in proportion to their small bodies than in adults. And every sweetheart T. rex was covered with a layer of downy feathers. What's more, T. rex's feathers probably grew along the animal's head and tail in adulthood, according to new reconstructions that represent the most accurate models of the dinosaur to date. These and many more T. rex surprises abound in T. rex: The Ultimate Predator, a new exhibition opening March 1 1 at the American Museum of Natural History (AMNH) in New York City. While T. rex is one of the most iconic dinosaurs, the exhibition presents new discoveries that transform scientists' understanding of this colossal carnivore and its tyrannosaur cousins, all of whom probably also had feathers. [In Images: A New Look at T. Rex and Relatives] Most of the tyrannosaur species presented in the exhibition were unknown to science before 2000, Martin Schwabacher, an exhibition author at AMNH, told Live Science.

Most of the tyrannosaur species presented in the exhibition were unknown to science before 2000, Martin Schwabacher, an exhibition author at AMNH, told Live Science. Early tyrannosaurs first appeared about 167 million years ago, about 100 million years before T. rex ruled the war. These early tyrannosaurs had relatively long arms, and were smaller and faster than the giant T. rex.

But even T. rex was not always huge. The exhibition is minuscule and endearingly fluffy model of a T. rex hatchling emphasizes the dramatic growth of the dinosaur, as it balloons from a turkey size to a giant adult. At the time, it was about 20 years old, a fully grown T. rex would be between 12 and 13 meters high in the hip, between 12 and 13 meters from nose to tail and weighing about 6 to 9 tons (5 500 to 8,000 kg).

T hough T. rex has long been known to have dramatically underestimated “arms” for his body size, few of these species’ front legs have been recovered from the fossil record, Norell told Live Science, and based on the few fossil arms that the paleontologists have recently discovered, are the stupid arms of exhibition adults The T. rex model is even smaller than what they have previously described, Norell said. However, this does not mean that T. rex’s arms were weak or useless.

“They are not delicate, the legs are very robust, the joints are mobile and it looks like they were well muscled,” Schwabacher said. In T. rex hatchlings, the proportions of their arms were a much better match to their body size, meaning that very young T. rexes may have been able to use their arms to grab byte, as other small tyrannosaurs probably did.

An adult T. rex weighed about 6 to 9 tons (5,500 to 8,000 kilograms).

] T. rex may also have used his arms and claws to throw on prey that it had already hit down With its massive head and jaws, Schwabacher said, but with a little force calculated to 7,800 pounds-force (34,500 newtons) – the strongest of all animals that live or extinct – T. rex probably didn’t have to do much with their arms r to suppress a meal.

“The head was adapted to apply pressure until the legs just exploded,” Schwabacher said.

T. rex: The Ultimate Predator is shown on AMNH from March 11, 2019 to August 9, 2020.
