1 Tyrannosaurus vs. Triceratops

Original air date: August 28, 2005

Tyrannosaurus

Triceratops

Face Off

An even match. In the episode, it is shown that if the rex makes an attack, it might attack the Triceratops, but if the plant eater discovers a booby trap, he could beat his opponent and kill it. The T. rex is seen stalking the Triceratops. It suddenly runs out of the bush and being fast, it takes the Triceratops. The rex bites into the Triceratops' neck, knocks it down and eats it alive. The T. rex is wandering through the forest looking for a tasty meal. It soon comes across two male Triceratops battling. While the two are done battling, the Tyrannosaurus singles one of them as a target. After picking its victim, the T-rex charges, but the Triceratops finds it just in time and turns away to face the hungry killer. The T-rex seizes the horn of the Triceratops and breaks it off. The herbivore tries to retreat again, but the T-rex chomps on his frill. After making a loud charge, the Triceratops slashes one of his horns into the T-rex's belly. The T-rex limps away, falls to the ground and slowly dies. The Triceratops then watches his attacker die and goes away to finish another day of eating.

2 Velociraptor vs. Ankylosaurus

Original air date: September 4, 2005

Velociraptor

Ankylosaurus

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 the raptors drives a claw into the dolly's neck, killing her. The Velociraptors then have the female baby as their payback.
