- The four-year-old and adult Hatchling models show us new faces of the famous predator.
- They are part of the T. rex: the ultimate predator exhibition from March 2019 to August 2020.
- You may want to pet the feathered newborn. Do not
There is no doubt that the adult Tyrannosaurus Rex was a formidable predator, with a powerful bite that could explode the head of a victim of force. Of course, much of what we "know" about T. rex is informed speculation based on incomplete information. Palaeontologists at the American Museum of Natural History (AMNH) in New York are about to unveil the results of a remarkable project. They built beautiful models of the T. rex as a newborn, at age four and in adulthood, based on the latest discoveries and reflections. Their intention is to provide the most scientifically accurate renderings ever made. T. rex as part of their T. rex: the ultimate predator exhibition that will take place from March 11, 2019 to August 9, 2020. The biggest surprise is the newborn: who has ever thought T. rex could be so, well, crazy-cute?
Recent fossil discoveries

With the discovery of more fossils, we are learning more and more about the Tyrannosauroidea family. The first discovery of a feathered dinosaur, the Sinosauropteryx prima in 1996, suggested that we could have imagined the ancient creatures, including T. rexwrongly. More recent discoveries such as Yutyrannus huali only reinforced this suspicion. In addition, archaeologists began to find Tyrannousaur fossils for infants, which allowed the NMHS team, led by Mark Norell, to realistically imagine T. rex at three stages of life for the Ultimate Predator exposure.
Not all tyrannosaurs were T. rexes – there were dozens of species of Tyrannosaurs, and no other was so big. the Ultimate Predator show includes a number of them including the Dilong paradoxus. Most were about the size of a T. rex hatched in adulthood. All were, however, dangerous predators – and the AMNH exhibition will feature new representations of various family members. More Tyrannousaurs were fast runners, unlike teenagers and adults T. rex, a death machine with slower movement. (The baby ran.)
Informed Riddle
There is still a lot of guesswork involved, but between what is visible in the fossil record and what we can see today in T. rex As parents live, there is no doubt that experts are getting closer and closer to the complete understanding of these creatures that roamed the Earth for the last time 68 million years ago. Many of these family ties can be inferred, including eating and parenting behaviors and various yet unknown physical characteristics. For example, fossilized T. rex the footprints are almost identical to those of the modern emu, although they are larger, so we can deduce their feet.
Speaking of skin, contrary to the traditional belief that T. rex the skin looked like that of a lizard or contemporary snake; experts now suspect that it was actually a more leathery coating, similar to that of a chicken foot or a turtle leg.
The new AMNH models reflect the latest theories regarding every detail of their physiognomy.
The little T. rex

About 60% of T. rex Newborns – the size of a turkey – probably did not survive until their first birthday. The fluffy feathered Tykes grew rapidly, about 140 pounds per month, but it took them 20 years to reach their normal size. Experts say they were small, fast predators with many small, needle-like teeth. Like the modern Komodo dragons, they probably fed on insects and smaller vertebrates before becoming adult foods.
T. rex, four years old
By the time T. rex was around four, he was as tall as any other norex tyrannosaurs. (AMNH says it's about five times the size of a four-year-old human boy.) It was completely variegated, with good teeth for slicing and cutting, as opposed to crushing, the specialty of the company. # 39; adult. T. rex. At this stage, T. rex also had long arms – it is thought that they stopped growing before reaching their actual size, which resulted in the strangely tiny arms of the adult T. rex.

Even more scary than before?
It's the scary bad boy (or girl) we know and fear, even though you probably have more feathers than you might think. The monster measured up to 40 feet long and weighed between 11,000 and 15,500 pounds.
T. rex Banana-shaped teeth and powerful jaws could hold 7,800 pounds of force, about the weight of three cars. It was one of the few creatures to be able to spray and digest the bone of solid prey. (30% to 50% of T. rex The coprolites, fossilized poop, are actually crushed bones.)
If that were not enough, we now know that T. rex the senses were super-sharp. The orange eyes looked like hawks and were far enough apart from each other to T. rex had a great vision in depth. The examination of his brain envelopes also suggests an exceptional sense of smell and hearing.
The new exhibition presents a projection of one of these nightmares on the ground in a shadowy theater.
L & # 39; exposure
If you have the chance to visit the AMNH for the T. rex: the ultimate predator exhibition, you will have the opportunity to approach – safely – with T. rex.
- They will have a life-size final model of an adult T. rex, is full of feather plates.
- There will be several reenactments of newborns as well as a four year old T. rex.
- A roaring mixer will allow visitors to build their own T. rex roars by combining the vocalization of related animals.
- You can walk in an interactive Cretaceous environment.
- Dig in a fossil "research station" with all the tools that a paleontologist might desire: a scanner, measuring instruments and a microscope.
