If someone asks you what is the largest carnivorous dinosaur in the world, you may say without hesitation: "Tyrannosaurus rex!"
It should be said that if your answer is wrong, it would be unfair to you, because Tyrannosaurus rex is indeed described as the largest carnivorous dinosaur in the world in many books about dinosaurs.
But now we want to tell you that Tyrannosaurus rex did play the role of the largest carnivorous dinosaur in the past, but now, its "champion" status has given way.
In August 1993, Argentinian paleontologists discovered a carnivorous dinosaur in Neuquen Province. Its fossil materials include thigh bones, hip bones, tailbones and mandibles with teeth. Because its thigh bone is 1.4 meters long and its teeth are as long as an adult's forearm, scientists believe that this dinosaur that lived 110 million years ago was 12.5 meters long and weighed an estimated 8 tons, which is 10 centimeters longer than the King of Tyrannosaurus Rex named "Su". Scientists speculate that this dinosaur used its thick hind legs to support its body and walk on two legs, and its short forearms were only used to grab food. Its huge teeth can tear apart any prey.
How much prey would such a large carnivorous dinosaur have to eat at one time to satisfy its appetite? Coincidentally, in the same area, paleontologists also discovered a huge vegetarian dinosaur. This vegetarian dinosaur was more than 30 meters long and weighed nearly 100 tons. It is possible that this huge vegetarian dinosaur was the main prey of the huge carnivorous dinosaur.
