Some birds, some pterosaurs (which is which?)

  1. What ?!?!?! You're actually trying to use artists' reconstructions as hard scientific evidence?!?! Yes, pterosaurs look superficially like birds, but that's just convergent evolution. Champsosaurus looks a lot like a crocodile, but does that make it the ancestor of crocodiles? Definitely not.

  2. Rather than convergent evolution I am suggesting homology.
