The Truth About Killer Dinosaurs

The Truth About Killer Dinosaurs is a two-part BBC documentary, presented by Bill Oddie, in which a group of scientists test out the strength of dinosaur weaponry using biomechanics. The first episode determines the winner of a battle between Tyrannosaurus and Triceratops, and the second compares the strength of an ankylosaur and Velociraptor. The programmes were broadcast on BBC 1 in August and September 2005. In the US, The Truth About Killer Dinosaurs was known as Dinosaur Face-Off.

These are the episodes and the evidence revealed in them.

An even match. In the episode, it is shown that if the Tyrannosaurus makes a surprise attack, it might kill the Triceratops, but if the herbivore discovers the trap, it could beat his opponent and kill it.

Outcome 1: (Winner, Tyrannosaurus) The T. rex is seen stalking the Triceratops. It suddenly runs out of hiding, and being faster it overtakes the Triceratops. The T. rex bites into the Triceratops' neck, knocks it over, and eats it.

Outcome 2: (Winner, Triceratops) The T. rex is wandering through the forest looking for food. It soon comes across two fighting Triceratops. When the two are done fighting, the T. rex singles out one of them as a potential target. After picking its victim, the T. rex charges, but the Triceratops sees it just in time and turns around to face its attacker. The T. rex seizes the horn of the Triceratops and breaks it off. The herbivore tries to retreat, but the T. rex chomps on the Triceratops' frill. After doing a mock charge, the Triceratops charges at T. rex and slashes its horns into the latter's belly. T. rex limps away, falls down, and slowly dies. The Triceratops watches it die and then goes back to foraging.

The ankylosaur would win, although Velociraptor could easily kill young ankylosaurs, which have easily penetrable armor.

Outcome 1: (Winner, ankylosaur) The ankylosaur is being harassed by two Velociraptor. They try to attack it multiple times but its armor proves too thick. The ankylosaur eventually drives them away by swinging its tail (one blow would have killed the Velociraptor).
