Pterorhynchus (Rhamphorhynchidae)
BASAL EUPARAVES
Scansoriopteryx (Scansoriopterygidae)
Note that in cladistics terms, basal Euparaves did not evolve from Pterorhynchus, but rather they share a common ancestor.
In non-cladistic terms, we could say that basal Euparaves evolved from a creature like Pterorhynchus. We can see that that is credible, from the drawings above.
