Did you love dinosaurs when you were a kid? Probably. But how much do you actually know about them? Dinosaurs and other prehistoric animals are some of the most diverse creatures to have ever roamed the Earth. Some of these creatures were as small as chickens, but some were bigger than we could easily imagine. Today, we’re going to take a look at the 25 Biggest Prehistoric Animals To Ever Exist!
The largest pelycosaur and predecessor to the modern day turtle weighed roughly 2 tons!
A Therapsid, Moschops was pretty much the cow of the Permian period. 225 million years ago this 2,000 pound predecessor to the mammals lumbered across the African plains, possibly in large herds.
This Triassic Archosaur was basically the forerunner to the dinosaurs. This interestingly named predator weighed over 1 ton.
As the biggest Mosasaur, this creature was over 50 feet (15 meters) long and weighed more than 15 tons. In fact, they were the last underwater apex predator before sharks took the reigns.
Although it only weighed 3 tons, the largest Plesiosaur was nearly 45 feet (13.7 meters) from head to tail. As an underwater predator, it mostly fed on small fish and squid.
