The Darwinopteridae display a mosaic of features for both Rhamphorhynchoid and Pterodactyloid species.  For this reason the family is considered an intermediate between the two suborders.

These pre-pterodactyloid species are middle Jurassic in age.  This is a time where there are few fossils available in the sediments, so the full picture of this transition is not clearly understood.
