Ankylosaurs Had Composite Armor

An anonymous reader writes "Ankylosaurs were the most heavily armored dinosaurs. Researchers thought their protective plates were a lot like modern crocodiles. But a new study by a University of Bonn grad student Torsten Scheyer found that fibers in the plates were woven for strength and lightness much like Kevlar or fiberglass. Good thing, as ankylosaurs had to contend with T. rex."

Consensus?

All depends who you pick for your consensus.

I will ask you to label two modern creatures to show why talking about t-rex eating behaviour is so futile.

Would you label the Hyena as a predator or a scavenger? And the lion?

Modern studies show that the scavenger Hyena kills a higher percentage of its food then the lion. Yet many still label the killer hyena as the scavenger and the lion known to eat hyena left overs as the predator.

Some people claim that t-rex build was unsuitable to hunt (head to big unable to run for long). Some claim that it build was exactly right to an ambush style hunt where it would deliver one large trauma wound and then use its nose to track the animal as it slowly died.

The same nose could also be used to find already dead prey.

Most like t-rex filled both roles shifting from one to the other as circumstances dictated. There are pure predators who refure to eat already dead animals but they are rare. Most predators are also scavengers and even some well known herbivores eat meat if they come upon it.

Talking about the movie. If you want to nitpick then nitpick that movie itself describes that the T-rex has a good nose but is somehow unable to small a scared human right infront of it. Even my cat spots a meal if you rub its nose in it. And this animal mews when I open a paint can.
