A theropod tooth reminiscent of the teeth of the North American species Richardoestesia gilmorei (Dinosauria: Theropoda) has been identified on the basis of its overall morphology and its rectangular and minute denticles. It was found associated with a dinosaur nesting site in deltaie deposits of the Aren Sandstone Formation near Tremp (Campanian, Late Cretaceous, south-central Pyrences, Spain). These preliminary results extend the fossil record of this taxon in Spain and would support the hypothetical survival of an Early Cretaceous Euramercian theropod lineage as far as the Late Cretaceous of southwestern Europe.</p
