Crocodiles have existed as living fossils on Earth for more than 200 million years, and in the long process of evolution, four extremely large crocodiles have appeared on Earth. All four crocodiles are more than ten meters long, and with a sharp tooth across the water and land, even a beast like the Tyrannosaurus rex cannot match it.
The first: the emperor crocodile
The emperor crocodile may be the largest crocodile found so far, according to the fossils found so far, the length of the emperor crocodile can reach thirteen meters, and the theoretical estimate of body weight can reach 8 tons. This crocodile is actually in basically the same era as the dinosaurs. In that era of giant beasts, the emperor crocodile was almost the only creature that could compete with dinosaurs. If in the water, the emperor crocodile is the first overlord who deserves to be the first overlord, standing at the top of the food chain, and really has no natural enemies.
The second type: acanthocons without acanthosis
The spiny crocodile lived in the same period as the emperor crocodile, but compared with the distribution range of the emperor crocodile, the distribution range of the spiny crocodile is slightly narrower, and they are mainly concentrated in some areas of North Africa, and there are few fossils left. Although the spiny cavity crocodile is not as large as the emperor crocodile, it can reach a length of up to ten meters, which also belongs to the prehistoric giant crocodile. It's just that the teeth of the spiny crocodile are relatively small, and there is not much advantage in the bite force.
The third species: the Prussian crocodile
Now we mention the large carnivores of South America, caimans and Amazon borers. But if you push the time to the Cenozoic period, these two creatures are completely insufficient. At that time, in the Amazon River Basin, there lived a giant crocodile with a body length of more than ten meters, the Prussian crocodile. In fact, this crocodile named The Prus crocodile may be the largest crocodile with the skull found so far, and according to fossil analysis, the skull of the Prussian crocodile may reach two meters long, belonging to a strange large-headed crocodile. Its bite force should be above that of the Tyrannosaurus rex.
The fourth type: crocodiles
In the late Cretaceous Period, 75 million years ago, the United States and parts of Mexico lived a giant crocodile over 10 meters in size, the alligator. Because crocodiles eat a lot, most of their hunting objects are dinosaurs. Although crocodiles do not actively attack some large carnivorous dinosaurs, small and medium-sized dinosaurs with a size of less than 2 tons are often targeted by crocodiles. Of course, if there are large carnivorous dinosaurs to attack, the crocodile is not afraid at all. With its own armor, the crocodile can concentrate on attacking the dinosaur's next three ways, but the dinosaur cannot form a positive impact on the crocodile.
