T.rex Vs Giganotosaurus

Vital Statistics

Tyrannosaurus rex "tyrant lizard king"

lived at the end of the dinosaur era during the Late Cretaceous period, approximately 65 million years ago. One of the largest and most ferocious meat-eating dinosaurs ever discovered, the T.rex was over 40 feet long, stood over 20 feet tall and weighed about 8 tons. It's jaws were up to 4 feet long and It had 7-inch long serrated teeth, and had up to 50 teeth in its mouth.and was found in North America and Eastern Asia.HEIGHT:23 feet (7.0 meters)LENGTH:50 feet (15.2 meters)WEIGHT:16,000 pounds (7,258 kg)(carnivore)Lived about 85-65 million years ago. By the time T. rex was a “teenager,” it was already more than 25 feet (9 m) long. T. rex grew very fast, gaining about five pounds (2.3 kg) a day during adolescence.Scientists believe that T. rex’s rapid growth meant it was warm-blooded like mammals, not cold-blooded like reptiles. Paleontologists have discovered and excavated about 20 T. rexes, all in North America, in Texas, Utah, Wyoming, Montana, Alberta, and Saskatchewan.Tyrannosaurus rex's arms were only about 3 feet (1 m) long, and it had 2-fingered hands. T. rex's principal habitat were forests.The female was the larger of the species and was more robust.
T.rex had about 200 bones in its body.Fossilized T. rex dung has been found - it contained crushed Triceratops frill, so large plant-eating dinosaurs were certainly included in T. rex's diet.
The first Tyrannosaurus rex fossil was discovered by the famous fossil hunter Barnum Brown in 1902. T. rex was named in 1905 by Henry Fairfield Osborn. T. rex died during the K-T extinction, which may have been caused by a huge asteroid impact that changed the Earth's climate. T. rex's footprint was 1.55 feet (46 cm) long (although its feet were much longer, about 3.3 feet (1 m) long; T. rex, like other dinosaurs walked on its toes). Most paleontologists think T. rex was an active predator but there is a minority viewpoint that it was mostly a scavenger. In 2005 A Tyrannosaurus rex fossil yielded the only preserved soft tissues ever recovered from a dinosaur. Taken from a 70-million-year-old thighbone, the structures look like the blood vessels, cells, and proteins involved in bone formation.

Giganotosaurus carolinii

Pronounced:Jig-an-o-toe-Saw-rusDiet:Carnivore (Meat-Eater)Name Means:"Giant Southern Lizard"Length:43 feet (14 m)Height:17 feet (5.5 m)Weight:7 tons (6,800 kilos)Time:Late Cretaceous - 100 MYA, lived about 95 million years ago, during the late Cretaceous period. This was about 30 million years before Tyrannosaurus rex, which was among the last of the dinosaur species alive before the Cretaceous-Tertiary extinction 65 million years ago. Fossils: Rodolfo Coria, a paleontologist from the Carmen Funes Museum in Neuquen, Argentina, excavated the Giganotosaurus from the Patagonia region of Argentina (in southern Argentina), which was originally (in 1994) found by a local auto mechanic whose hobby is hunting dinosaur bones. In honor of the discoverer, Ruben Carolini, the huge dinosaur has been named Giganotosaurus carolinii. It was named by Coria and Salgado in 1995. It had a very strong body and a mouth full of teeth like steak knives. Just its head alone was almost 6 feet (2 m) long! The largest Giganotosaurus found is estimated to be 14.3 m (47 ft) long and weighed up to 8,000 kg (9 tons), surpassing Tyrannosaurus rex by almost 2 m and 2,000 kg (6.5 ft and 2.2 tons). The specimen's skull was the size of a bathtub, measuring 1.95 m (6 ft 5 in). Though longer and heavier than T. rex, G. carolinii was relatively less robust and had a much smaller braincase that was the size of a banana. A well-developed olfactory region means it probably had a good sense of smell. . Giganotosaurus, along with relatives like Tyrannotitan and Carcharodontosaurus, are members of the carnosaur family Carcharodontosauridae.

Top Five Meat-Eating Dinosaurs in size order:

1. Giganotosaurus
2. Carcharodontosaurus
3. T. rex
4. Spinosaurus
5. Allosaurus

Me Thinks........

But Out of T.rex and Giganotasaurus who would win in a confrontation? I think although T.Rex was indeed smaller than the two, I think with its superior intelligence and having greater vision perception I believe T.rex would triumph between the two giants.
