T. Rex

The Tyrannosaurus Rex is a three-part fossil that can be donated to the museum in all games to date. It is the highest-scoring fossil (when complete) in terms of HHA points. The T-Rex Skull is also the highest-selling fossil in the game, as it is sold for 6,000 bells.

"Why, this means... Yes! Tyrannosaurus! It's complete!!! Oh, such joy! Such unfettered delight! Truly... this is splendid. I am quite beside myself. I’m practically molting with all this excitement! Now then, where to begin? Tyrannosaurus... A magnificent beast... A highly evolved theropod, the ‘tyrant lizard’ was one of the largest carnivores of the late Cretaceous period. It had a large head, a short, muscular neck, a barrel-like body, and powerful hind legs with three-taloned feet. Its skull was enormous, and its vast jaws were filled with dagger-like teeth, the largest of which were 6 inches long! T-rex was 40 feet long from nose to tail. Resistance to its powerful attacks was an exercise in futility! Garrrr! Oh my! Oh, terribly sorry! I beg your pardon, eh wot? I seem to have been overcome by momentary savagery. Hoo!"

"...Amazing! Stupendous! The T. rex has been completed! Hoo, the sheer stupefication of it all! T. rex is, of course, short for Tyrannosaurus rex! It lived until the final days of the dinosaurs and was a fearsome predator, wot? Just imagine how it would rend and tear apart its prey with those huge jaws and sharp teeth! Blech! Vivid! It was also very heavy, so the theory goes that is wasn't particularly fast. ...So, if it attacked, you could escape from it pretty easily, I should think..."

In New Leaf
"The famous tyrannosaur was one of the largest and strongest carnivores of its day. Though it could reach more than 30 feet in length, it was capable of speeds near 20 mph. Its hind claws were powerful, as were its razor-sharp teeth. This made the T.rex fearsome indeed."

In New Horizons
"I'd say that T. Rex is the 800-pound gorilla of the dinosaur world, but it likely weighed well over nine tons. This fearsome chap is practically synonymous with the word 'dinosaur,' and for good reason! At up to 42 feet long with banana-sized teeth, it was one of the largest carnivores ever to walk the earth. It's unclear how fast T. Rex was since estimates vary wildly... I am just relieved I will never have to escape one. Hoo. "

Further Information
Tyrannosaurus rex, often abbreviated as T. rex, is one of the largest and most well-known carnivorous dinosaurs. It lived in western North America at the end of the Cretaceous, 68-66 million years ago. It could reach over 12 meters in length and weigh 8-14 metric tons. More than fifty specimens have been found, and some hypothesize that the genus Tarbosaurus from Asia may in fact be synonymous with Tyrannosaurus.
