![]() It also lived in forests where herbivorous dinosaurs found their food. Rex was native to North America and modern-day Mongolia. It lived in forests where its prey, herbivorous dinosaurs, could find their food. The Giganotosaurus was native to South America. Rex would sometimes fight each other for food, and the winner would eat the loser. Rex were both carnivores that preyed on large herbivore dinosaurs. This was useful since its main mode of hunting was crushing prey with its powerful jaws. Rex had a thick tail that helped it move quickly as well as balance its massive head. The Giganotosaurus was fairly agile for its size, thanks to its tail that made navigation easier. Rex's teeth were serrated, conical and continually being replaced.īoth these species of dinosaurs walked on two large, powerful back legs. Giganotosaurus teeth were eight inches long, sharp, short and narrow with serrated edges. It had two puny arms that didn't even reach its mouth, and ended in two-fingered "hands." Its tail was powerful and pointed, helping the T. Rex also stood on two muscular back-legs. Its tail was thin and pointed and helped it with agility. It had three-fingered "hands" that ended in sharp claws. The Giganotosaurus stood on two large and very powerful back legs. The back of the skull had a steep forward incline. The Giganotosaurus had a long skull which was larger than most adult humans, with a relatively small brain. Rex, paleontologists compare the size and characteristics of these two creatures and discuss whether they were carnivores or scavengers. Rex grew to be 40 feet long and 15 to 20 feet high at the shoulder. The Giganotosaurus grew to be between 40 to 46 feet long and 23 feet high at the shoulder. ![]() Rex were huge theropods, i.e., dinosaurs that walked on two legs.

Larger than adult humans 1.9 meters long slightly small brain (still bigger than all herbivores though) long skull back of the skull had a steep forward incline, giant teeth. About 13 feet at the hip when fully grown.Ĥ,000 to 7,000 kg (about 9,000 to 15,000 pounds) More than 30 partial Tyrannosaurus specimens have been found since.ġ7-21 feet.

United States (Texas, New Mexico, Colorado, Wyoming, South Dakota, North Dakota, and Montana) and Canada (Alberta, Saskatchewan). Preyed on armored herbivorous dinosaurs, other T. Its legs were extremely big and powerful.Ĭarnivorous preyed on giant titanosaurs, other predators, other Giganotosauruses.Ĭarnivorous. The T-Rex's powerful tail allowed it to move quickly could "run" up to 19 mph. Late Cretaceous Period (67 million years ago)īiped walked on two large, powerful back legs fairly agile could travel up to 31 km per hour.īipedal. Middle Cenomanian stage of the Late Cretaceous Period (97-93 million years ago) But I will still give you the treat of seeing Stan in my Sta.sh.Differences - Similarities - Giganotosaurus versus Tyrannosaurus comparison chart Since, Scott Hartman is so touchy about his skeletals that nobody is allowed to use them. Unfortunately I will not be able to show, Stan. Though Sue may not be the largest of the dinosaurs here species still reign as the rulers of the Cretaceous and the dinosaurian kingdom. Sue measures 40ft (12m) long and stands 12ft (3.66m) tall, adding the cervical neck Sue stands a little more close to 13.6ft (4.14m) tall *this evidence proven in earlier height estimates*. Recorded estimates from estimated was out of proportion proven through a study by Kronosaurus82 iconkronosaurus82: measuring the skull by 140cm instead of 180cm. And now time for the GRAND FINALE, Tyrannosaurus Rex! Here is the queen herself, specimen Sue is or now was the largest known Tyrannosaurus to ever have been discovered. ![]()
