Before T. rex was fearsome, it was really cute

Hatchling, four-year-old, and adult models show us new sides of the famous predator. They're part of the T. rex: The Ultimate Predator exhibit running from March 2019 to August 2020.

There is no doubt that the adult Tyrannosaurus Rex was a prosperous predator, with a powerful bit that could cause the head of a victim to explode from sheer force.

Latest fossil discoveries

(AMNH / AMNH / R. Peterson)

As more fossils are discovered, we learn more and more about the Tyrannosauroidea family. The first discovery of a feathered dinosaur, the Sinosauropteryx fine in 1996, suggested we might have been picturing the ancient creatures, including T. rex incorrectly. More recent discoveries such as the Yutyrannus huali have only bolstered this suspicion. In addition, archeologists have found the infant Tyrannousaur fossils, and this has allowed the team at the AMNH, led by Mark Norell, to realistically imagine T. rex Ultimate Predator exhibit Not all Tyrannosaurs were t. rexes – there were dozens of Tyrannosaur species, and no others were as large. The Ultimate Predator show includes a number of them, including the Dilong paradox . Most were about the size of a T. rex hatchling as adults. They were all, however, all dangerous predators – and the AMNH exhibit will feature new representations of a variety of family members. Most tyrants were fast runners, unlike the adolescent and adult T. rex a slower-moving death machine. (The hatchling robbery.)

Informed guesswork

There’s still a fair amount of conjecture involved, but between what’s visible in the fossil record and what can be seen today in T. rex’s living relatives, there is little doubt that experts are ever-closer to a complete understanding of these creatures who last roamed the earth some 68 million years ago. A lot can be inferred from these family connections, including feeding and parenting behaviors and various as-yet-unknown physical features. For example, fossilized T. rex footprints are almost identical to the modern emu, both bigger and so inferences can be made about their feet.

Speaking of skin, contrary to the traditional belief that T. rex’s skin was akin to a contemporary lizard’s or snake’s, experts now suspect it was actually more leathery covering, similar to that of the foot of a chicken or the leg of a turtle.

(AMNH / D. Finnin)

About 60% or T. rex hatchlings – about the size of turkeys – probably didn’t survive to their first birthday. The down-feathered tykes grew quickly, though, about 140 pounds a month, but it still took until they were about 20 to reach full size. Experts believe that they were quick little predators with lots of tiny, needle-like teeth. Like the modern comodos, they are probably insects and narrower vertebrates before growing into their grown-up danger.

The four-year-old T. rex

By the time T. rex was around four, it was as big as other non- rex Tyrannosaurs . (AMNH says this is about five times the size of a four-year-old human boy.) It was fully feathered, with teeth good for slicing and cutting as opposed to crushing, the specialty of the adult T. rex . At this stage, T. rex also had long arms – it is believed they stopped growing prior to reaching full size, resulting in the poor arms of the adult T. rex .

Even scarier than before?

This is the terrifying bad boy (or girl) we know and fear, albeit likely With more than one thought you might have once thought. The sample was up to 40 feet long, weighing between 11,000 and 15,500 pounds.

T. rex’s banana-shaped teeth and mighty jaws could clamp down with 7,800 pounds of force – that’s about the weight of three cars. It was one of very few creatures ever to be capable of pulverizing and digesting the solid bone or prey. (30% -50% of rex coprolites, fossilized poop, is actually crushed bone.)

If that wasn’t enough, we now know that T. rex senses were super-sharp. Orange-sized eyes faced forward, hawk-like, and were set far apart that T. rex had great depth vision. Examination of its brain casings suggests an exceptional sense of smell and of hearing, too.

The new exhibit has a shadow-theater floor projection of one of these nightmares coming to life.

The exhibit

If you ‘ re fortunate enough to visit the AMNH for the T. rex: The Ultimate Predator exhibit, you’ll have the opportunity to get up close and personal – safely – with T. rex

  • They’ll have a definite life-sized model of an adult T. rex replete with patches of feathers.
  • There will be several hatchling reconstructions, as well as a four-year-old T. rex
  • A “roar mixer” will allow visitors to construct their own T. rex roars by combining the vocalization of related animals
  • You can wander through an interactive Cretaceous environment.
  • Dig in at a fossil “investigation station” with all the tools a paleontologist could want: a CT scanner, measuring tools, and a microscope
