Re: Important feathered dinosaurs
Personally,...I like Protoavis in that it indicates the presence of a true
avian form as early as the Triassic. (feathers assumed from the "quill
nodes" found in the wing structure).
Except that it doesn't according to most authorities, and there are no
"quill nodes" (just a ridge that might possibly have provided attachment
for something, maybe).
