The Truth About Killer Dinosaurs is a two-part BBC documentary film, directed by Bill Oddie, in which a group of men test out dinosaur weapons, using studies. Visual effects are done by MPC.^[1] The first episode determines the winner of a battle between Tyrannosaurus and Triceratops, and the second compares the strength of an Ankylosaurus and Velociraptor. The episodes were broadcast on BBC 1 in August and September 2005. In the U.S., The Truth About killer Dinosaurs was also known as Dinosaur Face-Off.

These are the episodes and the evidence revealed in them.

Original air date: August 28, 2005^[2]

• Evidence of head injuries on Triceratops indicates that Tyrannosaurus rex attacked Triceratops.
• Using a steel Tyrannosaurus rex skull, scientists learned that Tyrannosaurus could easily crush a small mini cooper.
• Scientists learn that Tyrannosaurus could run at 25 miles per hour
• Scanning an endo cast from a Tyrannosaurus rex skull, scientists theorize that Tyrannosaurus rex had a brain similar to that of a modern-day alligator.
• Tyrannosaurus had nice vision, and a big sense of smell.
• Tyrannosaurus could bite through bone, at a bite force of at least four tons per square inch.

• Doing a crash test with a Triceratops skull, made of solid resin, scientists learn that contrary to portrayals in the media, Triceratops probably did not charge at predators nor other dinosaurs, for its skull would likely break.
• Triceratops may have gored its predators.
• Triceratops was slower than Tyrannosaurus, but was more agile.

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.

• 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, Velociraptor's 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 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.

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.

• The Tarbosaurus appears in the second episode heart of death. It fights the ankylosaurus and loses it (the tail club breaks its leg).

• The Protoceratops appears in the second part heart of death in two fights against a Velociraptor. The first is a re-enactment of the fighting dinosaurs scene, while the second pits it against two Velociraptors, where the latter wins.
