An almost complete, ornithocheirid pterosaur from the Romulado Member of
the Santana Formation, NE Brazil is described. The specimen lacks a rostral
and dentary median sagittal crest and is sufficiently distinct from other
crestless taxa to warrant the erection of a new genus and species,
Barbosania gracilirostris gen. et sp. nov. It confirms the absence of a
crest as a genuine condition rather than a consequence of ontogenetic
immaturity and indicates a shift from the previously observed pattern of
suture closure in pterodactyloid pterosaurs, where partial fusion of the
extensor tendon process has occurred at a relatively small size. Several
specimens showing morphology similar to Brasileodactylus may instead be
more closely allied to B. gracilirostris.
