The biggest dinosaurs that lived on Earth

In fact, that images of the T.rex and the Spinosaurus are old and inaccurate. This is the last image for comparison, approved by Paleontologist that had actually worked with Spinosaurus:

In order: Spinosarus, Giganotosaurus, Tyrannosuarus and Suchomimus.

As we can see, Spinosaurus was long, over 3 meters longer than T.rex, but it was very low and rarely walked in two legs. It measured c.15 meters long and weighed c.9 tons (estimations of up to 20 tons are unreliable and most be discarded). T.rex measured c.13 meters long, but it was higher at the hips (c.4 meters) and weighed the same (c.9 tons too). Giganotosaurus was of the same size than T.rex, or probably 1 meter longer, using the largest specimen, but weighed comparative less, between 7 to 8 tons.
