Dinosaur eggs in the Upper Cretaceous of the Coll de Nargó area, Lleida Province, south-central Pyrenees, Spain: Oodiversity, biostratigraphy and their implications

The Coll de Nargó area (Lleida Province, south-central Pyrenees) has yielded thousands of dinosaur eggs distributed in more than 30 levels across 370 m of Upper Cretaceous Tremp Formation deposits. Two stratigraphic units yielding dinosaur eggshells, eggs and clutches, can be distinguished. Multiple eggshells were collected from up to 75 different in situ clutches, located in consecutive stratigraphical levels throughout the Mas de Pinyes...
