Ponerosteus a pterosaur?
Ponerosteus may be either a bird or a pterosaur (Fejfar et. al. 2005). Given the difficulties in telling isolated pterosaur long bones apart from the long bones of Mesozoic birds, the exact systematic position of Ponerosteus in Ornithodira is uncertain at best until histological analysis is performed on the holotype.
