More than three decades have passed since the discovery of anomalies in the abundance of platinum group elements (PGEs: Os, Ir, Ru, Rh, Pt, Pd) across the sections of Cretaceous-Paleogene (K-Pg) strata from Gubbio (Italy) and Caravaca (Spain), which have been attributed to a bolide impact. More than three decades have passed since the discovery of anomalies in the abundance of platinum group elements (PGEs: Os, Ir, Ru, Rh, Pt, Pd) across the sections of Cretaceous-Paleogene (K-Pg) strata from Gubbio (Italy) and Caravaca (Spain), which have been attributed to a bolide
impact. This remains one of the most significant findings in the field of Earth science. After the discovery, the PGE anomaly at the K-Pg boundary has been confirmed from more than 120 sites.
