Giganotosaurus - Meaning : Giant southern lizard

Giganotosaurus (meaning 'giant southern lizard') was a carcharodontosaurid dinosaur that lived 93 to 89 million years ago during the Turonian stage of the Late Cretaceous Period.

It is one of the largest known terrestrial carnivores, longer than Tyrannosaurus, but smaller than Spinosaurus. The largest Giganotosaurus is estimated to be 13.7 metres (45 ft) long, 5-5.5 metres (16.6-18.3 ft) tall, and weighed 5.2 tons. The specimen's skull was the size of a bathtub, measuring 1.95 metres (6 ft 5 in). Giganotosaurus surpasses Tyrannosaurus rex in length by almost 2 metres.

Titanosaur fossils have been recovered near the remains of Giganotosaurus, leading to speculation that these carnivores may have preyed on the giant herbivores. Fossils of related carcharodontosaurid fossils grouped closely together may indicate pack hunting, a behaviour that could possibly extend to Giganotosaurus itself.
