They lived in coastal swamps, open forests, and likely remained close to water sources. These water sources likely attracted wide variety of prey for these carnivores to feed on. Researchers found all of the Tyrannosaurus rex fossils today in North America.
Full Answer
Thing is, T. rex could run, just it wasn’t a speed runner, it was more adapted to marathon running. So while the highest estimates place it around 20 mph, which isn’t fast, it’s going to be holding that speed for a significant amount of time. How did the Tyrannosaurus rex hunt if it couldn't run?
“Tyrannosaurus” is Greek for “tyrant lizard,” and “rex” means “king” in Latin. When and where did T. rex live? T. rex lived about 66–68 million years ago during the Cretaceous Period in the western United States, including Montana and Wyoming.
Read on to learn about the Tyrannosaurus. While no one has seen this species in person, scientists have a decent estimation of the overall appearance of Tyrannosaurus. Based on fossilized specimens, the scientists estimate that T-rex stood approximately 12 ft. tall at the hip, and grew about 40 ft. long.
Tyrannosaurus rex has been found across Laramidia. For the sake of brevity, I will only describe the Hell Creek Formation climate, which is one area where the species lived.
Habitat of the Tyrannosaurus. These dinosaurs likely utilized a wide range of habitats. The landscape of their range was very different 65 million years ago, as was much of the world. Scientists believe that the T-rex lived in areas with high humidity and semi-tropical temperatures.
Based on fossilized specimens, the scientists estimate that T-rex stood approximately 12 ft. tall at the hip, and grew about 40 ft. long.
Tyrannosaurus. The Tyrannosaurus, commonly referred to as Tyrannosaurus rex, or T-rex, is possibly the most famous dinosaur in the world. The name is actually their genus and species name, Tyrannosaurus rex, and scientists believe there may be another species in the Tyrannosaurus genus!
Toothy Grin – One of the more menacing aspects of T-rex is their immense pair of jaws. This creature had an impressively large head. In fact, their head was disproportionately large, and required an extremely muscular neck to support it.
Mega Mystery – Just because the largest fossil we have found measured 40 ft. long, doesn’t mean that there were not larger specimens out there. Fossilization takes specific conditions, and only a small percentage of dinosaur remains underwent fossilization for humans to discover later.
The presence of T-rex teeth embedded in other T-rex fossils suggests that these creatures had either very high aggression towards one another, or they exhibited cannibalism. Evidence from closely related species also suggests they may have hunted in packs.
This does not necessarily mean that these creatures did not roam the entire American continent, but simply that these areas met conditions for fossilization. Archaeologists have found seven specimens in Montana, four in South Dakota, one in Wyoming, and one in Saskatchewan.
What does the name “Tyrannosaurus rex” mean? “Tyrannosaurus” is Greek for “tyrant lizard, ” and “rex” means “king” in Latin. So, Tyrannosaurus rex was “King of the Tyrant Lizards.”. When and where did T. rex live?
T. rex was certainly the biggest two-legged predator in its Late Cretaceous ecosystem, and it was one of the largest predators ever to live on land. Other species, such as Carcharodontosaurus, Giganotosaurus and Spinosaurus, were similar in size but lived earlier in the Cretaceous Period.
Birds are actually a type of dinosaur from the same group as T. rex. Both T. rex and birds had hollow bones and air sacs, and some members of the tyrannosaurid family even had feathers. Birds first evolved in the Jurassic, as did the earliest tyrannosaurs. Nation’s T. rex Facts.
