  Genus Giganotosaurus
Giganotosaurus was a carnivorous (meat-eating) dinosaur that lived in Argentina during the late Cretaceous period. between approximately 93 to 89 million years ago.

Giganotosaurus was up to 43 feet (13.2 meters) long, and the largest animals probably weighed approximately 6.2 tons.

Fossils of the giant Sauropod dinosaur, Titanosaurus, have been found near Giganotosaurus, and it is therefore thought likely that Giganotosaurus would have preyed on these herbivores. There is also evidence that dinosaurs in the same family as Giganotosaurus were pack hunters, and as a result, it seems probable that Giganotosaurus was too.

Giganotosaurus has a number of noteable features. These include:
  • Although larger than Tyrannosaurus rex, Giganotosaurus only has a brain about half the size.

  • Giganotosaurus has shorter and narrower teeth than Tyrannosaurus rex, and these teeth are particularly well adapted for slicing flesh.

  • The brain of Giganotosaurus has a well-developed olfactory region, and the animal probably therefore had a very good sense of smell.

  • Recent research suggests that Giganotosaurus may have been a fast runner, perhaps capable of speeds in excess of 30 miles per hour (14 meters per second).

Giganotosaurus Facts

Here is a summary of some of the key facts about Giganotosaurus:
  1. Giganotosaurus was a genus of dinosaur.

  2. "Giganotosaurus" means "giant southern lizard".

  3. Giganotosaurus was a member of the Saurischia ("lizard-hipped") order of dinosaurs. What this means, is that although Giganotosaurus was not closely related to lizards, it did have similarly shaped pelvic bones.

  4. Giganotosaurus was a Theropod - a member of a group of related bipedal dinosaurs that included the ancestors of birds (although Giganotosaurus was not itself an ancestor of birds).

  5. Giganotosaurus lived between about 93 million years ago and 89 million years ago, during the late Cretaceous period.

  6. Giganotosaurus lived in southern Argentina.

  7. Giganotosaurus was a carnivore (meat-eater).

  8. Giganotosaurus was a carnivore (meat-eater) with teeth adapted for slicing flesh. It is thought to have preyed upon herbivores (plant-eaters) such as the giant Sauropod, Titanosaurus. Fossils of close relatives to Giganotosaurus are suggestive of pack-hunting, and Giganotosaurus may well have hunted in packs too.

  9. Giganotosaurus was about 40 feet (12.2 meters) to 43 feet (13.2 meters) long.

  10. The largest Giganotosaurus weighed an estimated 6.2 tons.
