How pterosaurs flew still a mystery

Scientists still aren't sure how giant reptiles (known as pterosaurs) 65 million years ago managed to fly, reports MSNBC's Cosmic Log blog. First problem, they were huge. Second problem, their hind legs were too small to launch them into flight like modern birds.

Some experts suggest pterosaurs jumped off of cliffs and took flight like a hang glider. But some fossils have been found a very long ways from any cliffs or steep mountainsides.

The latest theory? Pterosaurs sprung from the ground using all four limbs, a "quadrupedal launch."

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
