Velociraptor Had Feathers

Spy der Mann writes "A new look at some old bones have shown that velociraptor, the dinosaur made famous in the movie Jurassic Park, had feathers. A paper describing the discovery, made by paleontologists at the American Museum of Natural History and the Field Museum of Natural History, appears in the Sept. 21 issue of the journal Science."

Not Velociraptor at all.

What was depicted in the movie Jurassic Park was clearly Deinonychus. Velociraptor didn't have that large inner claw. In fact, the name Deinonychus means Terrible Claw while Velociraptor means Speedy Predator. I suspect they misnamed the dinosaur in the movie because the name Raptor was more marketable to children.

the suspicion is that all dinosours had feathers.

Feather are made from the same stuff as scales, chitin (snakes and so on), its just a form of scale thats better suited to temperature regulation. Having feathers did not mean flight was even possible, that would have required specific adaption that feathers would probably have helped, but it would have been some environmental push, not the feathers themselves that caused birds to emerge.

Wow.

Dazzling camouflage works on humans, too

It was used in WWII. No real evidence it worked well, but the principle applies to predators. Who is going to miss a big galumphing thing charging towards them, no matter how well camouflaged? That's not the point. The point is to make the prey misjudge distance, direction, and speed, so that when you leap, they dodge the wrong way.

Humans use the same kind of visual shortcuts that other animals do. In fact, it's in the basic structure of the eye. The rods and cones in the eye are cross linked and inhibit each other, meaning that only large changes between adjacent cells are transmitted by the optic nerve. The brain then rebuilds a complete picture based on the edge and tone information transmitted.
