Species of pterosaurs
Pterosaurs have many kinds, sizes and shapes. The big one is like a living glider, and the small one is only as big as a sparrow. Some wear strange crowns on their heads, some have long tails with a diamond-shaped leaf at the tail; Some have alienated fangs, while others have no teeth. But they have a lot in common: they have wings, hollow bones and thin wings, which are conducive to flying in the air. They all have huge beaks and mouths and good eyesight. They prey on fish and insects, and some eat carrion and plants.
A conscientious pterosaur
For pterosaurs, raising offspring is a very laborious job. In order to avoid being hunted by other dinosaurs, they usually lay their eggs in places where other dinosaurs can't get close, such as cliffs and trees. Pterosaurs hatched their eggs and brought back food or vomited some undigested food to feed their young dragons until Smaller Pterosaurs learned to fly and hunt alone when he grew up. Because it takes a long time to feed and protect Smaller Pterosaurs, pterosaurs are likely to form teams and cooperate with each other during the breeding season.
