Top 10 Best Prehistoric Animals

The Top Ten
1 Tyrannosaurus Tyrannosaurus, meaning "tyrant lizard", from the Ancient Greek tyrannos, "tyrant", and sauros, "lizard" is a genus of coelurosaurian theropod dinosaur. It also had a tremendous bite force, the strongest of any Dinosaur and living terrestrial animal. Its bite force reached up to 12,800 pounds (roughly 5805 Kilograms).

Of course it would be on the top.


Not only the most well-known dinosaur, but also one of, if not THE most well-known prehistoric creature.

2 Smilodon Smilodon was a saber-toothed cat from North and South America that lived 1.5 million to 10,000 years ago. It had a short tail, but very strong legs and paws for catching big prey. It was also 7.2 feet (2.2 meters) from nose to tail. Smilodon's two main front teeth were up to 12 inches (30 centimeters) long. They were very sharp, but quite thin. Smilodon probably used them to stab into its victim, or to slash its flesh and cause gaping wounds so the prey bled to death. Smilodon could open its mouth very wide, ready to strike its prey as though cutting it with a big knife. It may have gone for the throat-to cut the blood vessels and breathing tube.
3 Megalodon The megalodon is an extinct species of shark which was about 59 feet (18 meters) long and hunted in the seas until about 1.5 million years ago. It was similar to today's great white shark-but three times longer and 20 times heavier. Megalodon had more than 250 huge, razor-sharp teeth and its mouth was so huge that it could easily swallow a person. The fossils of its teeth were once thought to be the tongues of dragons or similar beasts. Megalodon was in the same shark group as today's great white shark, mako shark, and porbeagle shark. All of these species of sharks are big, fast, fierce hunters-just like their prehistoric relative.
4 Triceratops Triceratops is a genus of herbivorous ceratopsid dinosaur that first appeared during the late Maastrichtian stage of the late Cretaceous period, about 68 million years ago in what is now North America.
5 Woolly Mammoth
6 Dire Wolf
7 Stegosaurus Stegosaurus is a type of armored dinosaur. Their fossil bones have been found in rocks dated to the Late Jurassic period, between 155 and 150 million years ago, in the western United States and Portugal.
8 Dimetrodon
9 Velociraptor Velociraptor is a genus of dromaeosaurid theropod dinosaur that lived approximately 75 to 71 million years ago during the later part of the Cretaceous Period.
10 Pteranodon Pteranodon lived during the late Cretaceous geological period of North America in present-day Kansas, Alabama, Nebraska, Wyoming, and South Dakota.
