Giganotosaurus

Giganotosaurus carolinii

Rivaling Tyrannosaurus in sheer size, Giganotosaurus carolinii was one of the largest terrestrial predators ever, about 12.5 meters, some 3.7 meters at the hip, and an estimated 6,800 kilograms. Its skull was longer and narrower than that of Tyrannosaurus, with a likely weaker bite but a wider gape suited to slashing wounds. Rodolfo Coria and Leonardo Salgado described this carnivore in 1993 from Patagonia, Argentina, dating to the Late Cretaceous, roughly 100 to 66 million years ago. As a carcharodontosaurid, it belonged to a different predatory lineage than the tyrannosaurs, showing that giant size evolved more than once among theropods.

Giganotosaurus was one of the largest known terrestrial predators, rivaling T. rex in size. It had a narrower, more elongated skull than T. rex and likely had a weaker bite force but could open its jaws wider.

Diet & Feeding

Carnivore

Giganotosaurus was a meat-eating predator. Carnivorous dinosaurs were active hunters or scavengers, equipped with sharp teeth and claws for catching and consuming prey. They occupied the top of the food chain in their ecosystems.

Time Period

Cretaceous Late Mesozoic Era

Giganotosaurus lived during the Cretaceous Late period of the Mesozoic Era, approximately 100.5 to 66.0 million years ago.

The final age of dinosaurs, featuring iconic species like Tyrannosaurus rex, Triceratops, and Velociraptor. Dinosaurs reached their peak diversity before the catastrophic asteroid impact at the Chicxulub crater ended the Mesozoic Era.
