Scientists say they finally understand how a giant prehistoric winged reptile, the pterosaur, was able to fly. Previous research suggested this heavy reptile, roughly the size of a giraffe, could not have built up enough momentum to become airborne. But a team of paleontologists from a British university said the pterosaurs used their powerful legs and arms to leap into the air, rather like pole vaulters in athletics.
