There's this old-fashioned line of thinking again .... or very perhaps lax
(All) dinosaurs aren't birds, though some dinosaurs are bird and all birds are
dinosaurs. Least of
all, dinosaurs didn't 'become' birds.
Same with the others you mentioned: archosaurs didn't become dinosaurs -
dinosaurs are merely a
subset of archosaurs. I'm not ready to call pterosaurs & crocodiles dinosaurs
unless they fall in
amongst Saurischia + Ornithischia.
& yes - i know that perhaps this is a very obvious response to the style of
comment DP made.
