A close-up of a colorful--if not handsome--Dimorphodon from Early-Jurassic England 195 million years ago. In the background is the ancient Tethys Ocean. While Dimorphodon's coloration is unknown, here an adult male's outsized beak has been colorfully decorated by drawing inspiration from modern day puffins and toucans.
Dimorphodon was a medium-sized pterosaur (flying reptile) with a wingspan of about four feet and a large head and puffin-like "beak ." Its long front teeth suggest that it was built for plucking fish from near the surface of the water. Its head and beak combined were about 9 inches long.
