A team of Spanish paleontologists has discovered the most recent dinosaur footprints in Europe on the banks of several Pyrenean rivers. The tracks correspond to the hadrosaurid subspecies known as "duckbill", which would have lived in this place until the end of the Cretaceous, when the impact caused the mass extinction of all non-avian dinosaurs.
The group analyzed the ichnites or marks present in the rocks that could only be carved during their formation process, so that they are undoubtedly attributed to the Mesozoic era. The scientists concluded that these tracks belonged to said hadrosaurid species because fossil remains have been found in the same geological formation. These reptiles would have inhabited the banks of the rivers of the Pyrenees 65.5 million years ago, before disappearing abruptly shortly after.
The study has been carried out by researchers from the University of Zaragoza, the Autonomous University of Barcelona and the Catalan Institute of Paleontology Miquel Crusanfont (ICP), who have been documenting the tracks of the last dinosaurs that inhabited the Earth for decades.
