I recall reading elsewhere calculations that pterodactyls should not have been able to fly, and the writer speculated that either the atmosphere was thicker back then to make it possible, or that they only flew by first climbing up tall trees or cliffs and jumping off. 'Afraid I don't have either reference handy. | |
