The end of the Cretaceous Period, 66 million years ago, marked the dramatic extinction of the dinosaurs. Until now, our understanding of this mass extinction has been largely shaped by fossils from North America. However, a recent study led by Verónica Díez Díaz from the Museum für Naturkunde Berlin, identifying two new dinosaur species from Romania, highlights the crucial role of European fossil discoveries in providing a more comprehensive picture of this extinction episode.
