Some feather morphologies are shared (that is, monofilaments, brush-like and tufted feathers and feathers with along-rachis branching), but others are not—for example, feathers with midpoint branching in pterosaurs and all feathers with barbules in theropods. Barbules are thus a unique innovation of theropod feathers.
This would be more accurate to say:
all feathers with barbules in
theropods[Paraves]. Barbules are thus a unique innovation oftheropod[Paraves] feathers.
Paraves* did not develop from any dinosaurs.
