T-rex chomps on its frill. After making a loud charge, the Triceratops slashes one of its horns into the T-rex's belly. The T-rex limps away, falls to the ground and slowly dies. The Triceratops then watches its attacker die and goes away to finish another day of eating. 2 Velociraptor vs. Ankylosaurus Original air date: September 4, 2005 Velociraptor Velociraptor was only the size of a turkey. Velociraptor had feathers. A robotic Velociraptor leg provides evidence that Velociraptor did not cut its meal. The fossil of a Velociraptor fighting a Protoceratops shows that the Velociraptor pierced the neck of its prey, possibly to impale the arteries or the vein. Velociraptor'''s wings were used for balance and agility, much like the wings of an African ostrich. Along with its claws, Velociraptors teeth were useful weapons.Velociraptor most likely hunted in small packs. Teeth of this dinosaur were found among its next meals. The claw provides evidence that the Velociraptor could not penetrate the ankylosaurus 's armor, it broke when tested on a croc's skin. Ankylosaurus Ankylosaurus armor was similar to a crocodile's, though significantly harder. Young crocs have no armor, especially on the neck. Baby ankylosaurus were probably similar. A robotic ankylosaurus tail shows that the tail club could break wood and bone with ease. This dinosaur's armour and club was used only on more threatening predators than Velociraptor. In the U.S version, it was known as Ankylosaurus, although Ankylosaurus itself lived in North America. The ankylosaurus in this fact have been Pinacosaurus. Face Off The ankylosaurus would win, although Velociraptors could easily kill young ankylosauruses, which have armor. The ankylosaurus is being attacked by three Velociraptors. They try to attack it four times but its armor proves thick. The ankylosaurus is able to drive them away by swinging its tail club (one hit would have killed one of the pack). The ankylosaurus is grazing and her young dollies come very close to her to avoid some danger, but one of them runs off to an unsafe playground. Two Velociraptors lay a trap around the female dolly, one of them bursts out of cover to stampede the dolly and the dolly escapes the Velociraptor, only to be driven into the claws of another one. The two Velociraptors attack the dolly, slashing her with their claws. The dolly tries desperately to save herself with her tail club, but is quickly overwhelmed. One of
