Pterosaur Flying Muscles

Pterosaurs are excellent fliers as you can see in this picture. They have giant lungs and the males are much larger than the females. You can see the difference in the bottom right corner. Another wonderful thing about pterosaurs is their crests - there are all different sizes and colours and they usually are colourful and wonderful. (Thanks wikipedia; Dave Hone; FossilGuy ; & again )
