风神翼龙

Tyrannosaurus Rex when we think about it, we tend to think of the big adult because thats the skeletons that we see, but we know that they didnt hatch that way. Once those eggs hatched, weve got an animal thats maybe, you know, three feet long, maybe

Tyrannosaurus Rex, though, lives in an entirely different world. A male devours a Triceratops carcass. Those powerful jaws smash into the meat of the animal. Those gigantic teeth pierce down through flesh. These well-rooted teeth are there to break i

Deinonychus instinctively knows to go for this giants weak spot, its neck. Youve got the windpipe there. Youve got the jugular vein, which if opened up will mean that that Sauroposeidon is dead meat. But death does not come quickly or pleasantly. For

Picture a living plane, and that gives you a sense of what Quetzalcoatlus would look like in life. And this is an animal that probably accelerates over 2.5Gs just on takeoff. Just beyond our comprehension. A Quetzalcoatlus is 10 times the weight of t

propel this creature weighing as much as a grizzly bear, from a dead stop to a launch speed of 50 kilometers per hour all in a fraction of a second. I think that seeing a pterosaur like Quetzalcoatlus actually take off would have to be one of the mos

Nothing this large would achieve powered flight until the 20th century, 65 million years later. And Quetzalcoatlus still may hold the record for flight duration. Probably stay aloft for a week. Probably it could have gone for 25, 26,000 miles in a si

I think that a big pterosaur on the ground wouldve been spooky because they would be moving around on all fours. Theyd probably have those sort of quick, precise movements like birds, but theyd be huge. Quetzalcoatlus lives by its own rules. Most mea
