Cacibupteryx caribensisi (Gasparini, Fernández, and de la Fuente, 2004) Oxfordian, Late Jurassic ~160 mya was considered a rhamphorhychid and a scaphognathid but it is a dorygnathid. Derived from a sister to Sordes, Cacibupteryx phylogenetically preceded all specimens of Dorygnathus.
Much larger and distinct from Sordes, the skull of Cacibupteryx had a longer rostrum and a shorter cranium. The palate was more solid with more extensive maxilla palatal processes, more robust pterygoids and larger ectopalatines.
PIN 2470/1 specimen of Sordes. This is the undescribed specimen that exposes the palate and is associated with a fish. Phylogenetically it appears to be more closely related to basal Cacibupteryx than to the other two Sordes specimens.
