%X in this work we study twenty teeth of spinosaurid theropod dinosaurs from the early aptian (early cretaceous) of morella (castell¨®n, spain). the teeth exhibit a mosaic of derived theropod characters such as ornamentation in longitudinal crests together with very small, uniformly sized denticles, which resemble baryonychine spinosaurids such as baryonyx. however, they also display other derived characters not found in european lower cretaceous spinosaurids. furthermore, the teeth share certain characters with gondwanan taxa such as suchomimus and irritator.
