This makes it tricky to even describe the pterosaur to bird theory. You have to use very qualified expressions, which even then, imply a dino to bird theory.
For example, I often use the phrase "basal paraves". This is intended to mean the long-bony-tailed feathered flying and secondarily flightless creatures. For example, Scansoriopterygidae.
But the category "paraves" is defined WITHIN the dino to bird theory. It assumes the dino to bird theory. So I obviously do not mean to include the baggage that the term "paraves" carries within the dino to bird theory.
For example, I do not mean that basal paraves evolved from dinosaurs and I do not mean to exclude oviraptors from the paraves group.
* for example consider this:
Paraves is a branch-based clade defined to include all dinosaurs which are more closely related to birds than to oviraptorosaurs.
