A study has unveiled what scientists think is the world’s biggest dinosaur.
A study, written by palaeontologist Gregory Paul, believe enormous dinosaur known as Argentinosaurus is the biggest ever.
The Argentinosaurus is believed to have lived between around 100 million and 90 million years ago.
The animal was first described in the early 1990s after several giant bones were found in Argentina.
Paul used new techniques to estimate the masses of the biggest dinosaurs known to science.
He found that the largest dinosaur by body mass was indeed Argentinosaurus, estimating that it had a mass of 65-75 tons.
