The Truth About Killer Dinosaurs

Loved it. But then again I love them all. Walking with dinosaurs. Walking with beasts. A beautiful combination of sound research, educated guesses and artistic license.

But they all raise new and puzzling questions.

In this case why did the T Rex SHAPE die out? The triceratops shape re evolved as the modern rhinoceros and ankylasorous as the modern tortoise. In the first age of mammals (walking with beasts) even the T Rex shape re evolved in the form of huge predatory birds.

But, after that, all of the top land predators went from hunting, almost exclusively, on two legs, to hunting only on four. The bear is the only modern carnivore that walks upright.

Really strange???
