A fossil bed in North Dakota preserves fish with Chicxulub impact glass trapped in their gills, evidence they were alive as asteroid debris fell 3,000 kilometres from the crater during the first hour or two after the strike that ended the age of non-avian dinosaurs
At the Tanis fossil bed in North Dakota, sturgeon and paddlefish have been found with glass spherules from the Chicxulub impact lodged inside their gills — evidence that the animals were breathing in ejecta from an asteroid strike 3,000 kilometres away, within roughly an hour of the moment the dinosaurs' world ended.
