A Petrosaur, which is a type of flying
dinosaur, is really mysterious. (Technically, they don't belong to any species
of dinosaur). So, every time I see their fossils, I wonder how they were able
to survive. First of all, they are too large, and look too heavy to even be able
to fly. Even they could fly, they couldn't turn round and back up quick
enough, they could only glide away based upon the structure of their bones.
Therefore, big question that comes to my
mind is ; What did they eat? Were there other flying creatures, that were
slowly enough to be caught by a gliding Petrosaur? In my opinion, based on the
the skeleton of the Petrosaur, I
conclude that they weren't able to take advantage of their power, and strength
when flying. In addtion, when they landed, they become prey because their only way to
escape from predators was to glide away or toddle. However, they were living
prosperously. There must be some advantage, or environmental factor that enabled
them to live successfully.
