Just a quick look at a good portion of Pterosaura. (No references used)

Pterosauria is NOT just 'Pterodactyls', Pterodactylus is it's own group of very very small toothed pterosaurs, and the first ever discovered


Pterosaurs are not dinosaurs. They are archosaurs like dinosaurs and crocodiles, but split off well before dinosauria
Pterosaurs had an odd sister-feather/fur like body covering called pycnofibers, not seen on any other animal, and thus were not naked or scaley

The first row is the 'primitive' Rhamphorynchoids
next down is an Anurognathid
next is an ornithocheirid
then a dsungaripterid

on the right we have a Pteranodon, somehow always confused with Pterodactylus, because people are uh.. really dumb?
below him we have a generic Azdarchid
and at the bottom is a Nyctosaurus

On the very right is a tapejarid
