Giganotosaurus

Giganotosaurus was about 12 to 13 metres (39 to 43 feet) long and weighed between 6 and 8 tonnes (6.6 to 8.8 short tons).12

Giganotosaurus was probably longer but more lightly built than Tyrannosaurus rex. Some scientists think it was larger, while others think they were roughly equal in size.13

Giganotosaurus was a meat-eater and likely the top predator of its environment. It may have hunted large sauropod dinosaurs, possibly in packs, or scavenged on dead animals.1

Giganotosaurus went extinct around 98 million years ago, long before the mass extinction that killed most dinosaurs 66 million years ago.1

Giganotosaurus fossils were discovered in Patagonia, Argentina, near Lake Ezequiel in the Candeleros Formation.13

Maybe up to about 50 km/h (31 mph) for a short dash. That is the top limit scientists worked out for such a big meat-eater, so it was probably often slower. Nobody knows for sure.1

No fossil evidence of feathers has been found for Giganotosaurus, and it is not known to have had feathers.3

Yes, Giganotosaurus is a dinosaur. It is a large theropod dinosaur from the family Carcharodontosauridae.1

The name Giganotosaurus means 'giant southern lizard' in Greek, because it was a huge dinosaur found in the Southern Hemisphere.1

There is no evidence that Giganotosaurus could swim. It was a land-dwelling dinosaur.3
