A fragmentary pterosaur proximal humerus from the basal member of the Exu Formation (Cretaceous) of Piauí, Brazil represents the first pterosaur element from this formation and may even be the first macrofossil from this dominantly arenaceous horizon. The fragment is tentatively assigned to Lophocratia UNWIN, 2003. The preservation is inconsistent with it having been reworked from the famously pterosaur-rich Santana Formation which under lies the Exu Formation in the region.
