Kurochkin thinks "sauriurines" (Archaeopteryx, Jibeinia, confuciusornithids,
enantiornithines, Patagopteryx) evolved from theropods, but ornithurines did
not. A ludicrous notion if there ever was one.
Not to me. I've thought about this on my own and believe its possible, or
actually, the other way around with a different twist in BCF.
Enantiornithines (Sauriurines) lived with Ornithurines. They did not have
families going from one group to another.
