Our research, published in Biological Reviews, offers a way to check. We found that two rival ways to estimate dinosaurs' body size - long thought to be fundamentally at odds - actually
However, the film, out this week, also features an even bigger star—quite literally. In Jurassic World Dominion, Alan Grant, played by Sam Neill, comes face to face with the Giganotosaurus, a

Giganotosaurus is thought to have been one of the largest theropod dinosaurs, but the incompleteness of its remains have made it difficult to estimate its size reliably. It is therefore impossible to determine with certainty whether it was larger than Tyrannosaurus , for example, which has been considered the largest theropod historically.

When it was discovered in Argentina in 1987, Argentinosaurus, the world's biggest dinosaur, shook the world of paleontology to its foundations. Ever since its discovery, paleontologists have argued about the length and weight of Argentinosaurus. Some reconstructions put this dinosaur at 75 to 85 feet from head to tail and up to 75 tons, while
Brontosauridae. Jaekel, 1911. Diplodocids, or members of the family Diplodocidae ("double beams"), are a group of sauropod dinosaurs.
