Resumen:
A fossil gastric pellet from the Danian ?Banco Negro Inferior? of the Salamanca Formation at Punta Peligro Locality (Chubut, Argentina) and its 3D preserved fossil content is here studied. The structure of the pellet and the condition of the enclosed bones suggests it was produced by a bird of prey, which are yet unknown from osteological remains in the Banco Negro ecosystem. The content of the pellet originated from a single anuran individual, representing a new species of the genus Calyptocephalella, described herein as C. sabrosa n. sp. The new find highlights the broad temporal, geographical, and taxonomic diversity of this frog genus in Patagonia?s geological past.
