This is important –
Pterosaurs were not dinosaurs. They were ancient flying reptiles who lived alongside dinosaurs.
Pteranodon
Pterodactyl
Rhamphorhynchus
Ornithocheirus
And many more. The science is evolving.
One thing you perhaps have not considered is that sometimes they were eaten by sharks. ‘How is this possible?’ you ask. ‘For sharks do not fly except in certain movies. Or did they in fact have wings in prehistoric times, back when dinosaurs ate our ancestors?’
You must understand firstly that sharks came before dinosaurs. They also came during and after dinosaurs, which implies that they are still here. They are their own subject.
You may also expand your insight by understanding that many pterosaurs ate fish. It is supposed that they dove into the water much like gannets and rose again with their meal. Pteranodons in particular had heavy necks, which supports this view. For the sake of this lesson we will adopt this supposition, though it may be wrong.
Some Pteranodon fossil specimens have shark bites. This is how we can experience the merge of sea and sky. How could the separation be natural, when a pterosaur could dive, and presumably a shark might leap into the air to snag a passerby skimming the surface? Close your eyes and drift in a small boat in the Western Interior Seaway that divides North America. You are far from land, and over the sides of the boat you see shadows of fish slipping by. Nearby a Pteranodon plummets and disappears into the water only to rise again with a fish in her beak. An Enchodus, maybe? Another Pteranodon dives in but does not return. You hold, your eyes lingering on the same spot of water. Only it isn’t the same spot anymore. There are waves after all. And as a boat drifts the relationship between two points becomes increasingly fluid.
This should be considered with devotion but not pondered. One can dispel flight by pondering too heavily. And water is dense enough.
