Re-evaluation of the age of some dinosaur localities from the southern Pyrenees by means of megaloolithid oospecies

Since the beginning of the 20th Century the Upper Cretaceous continental and transitional marine deposits of the southern Pyrenees have produced more than 220 dinosaur fossil localities. New discoveries and advances in magnestostratigraphy and biostratigraphy provide a robust biostratigraphical framework for the latest Cretaceous dinosaur faunas in the region, although the age of some localities has remained uncertain. Here, we re-evaluate the...
