Tyrannosaurus rex has been a media darling since (arguably) 1906, when The New York Times called it "the prize fighter of antiquity."

(1996). Giganotosaurus was discovered in the Candeleros Formation, which was deposited during the Early Cenomanian age of the Late Cretaceous, approximately 98-97 million years ago. To date, researchers have identified mere fragments of this dinosaur's skull, belonging to a second individualwhich is still enough to peg this dinosaur as a carcharodontosaur.

The specimen analyzed was up to 41 feet long (12.5 meters) from head to tail, and weighed between 6.6 and 8.8 tons (6 to 8 metric tons), the researchers estimated. Bear in mind that Giganotosaurus wasn't technically a tyrannosaur, but a type of theropod known as a "Carcharodontosaurus," and thus related to Carcharodontosaurus. Have any problems using the site?
