Big, fierce and extinct they may be, but 65 million years after the last one died, dinosaurs continue to pose questions for humans. Obvious ones like: What did they eat? How fast could they move? What did they sound like? What colour were they? And the really big one: If it happened to them, could it happen to us?
Paul Barrett, the leading paleontologist at London's Natural History Museum, says: "Enormously successful, living all over the world and a big rock from space knocks them out. It's a wake-up call to human arrogance. Some things you cannot predict and we are still vulnerable to being caught out."
Phew, that's far too deep for a Thursday morning. Here are some really cool places where dinosaurs survive.
1. The Dinosaur Capital of the World
Drumheller, in the Red Deer Valley of Alberta, Canada, was founded on coal but now thrives on another underground resource: dinosaur bones. Paleontology is a serious business here — the fantastic Royal Tyrrell Museum is both research centre and tourist attraction, a 26m-high fibreglass T rex haunts a large portion of downtown, and many businesses carry dino-related names in a manner that may remind you of Bulls. If you want to be reminded of Bulls.
