Researchers first identified the cause of the end-Cretaceous extinction by the discovery of the “iridium anomaly” — a 1-centimeter-thick (0.4-inch-thick) layer of sedimentary rock rich in ...
“It was the enrichment of iridium in Cretaceous/Palaeogene boundary sediments that was the highly convincing ‘smoking gun’ for the dinosaur extinction when (the) idea was first published in 198 ...
