The Chicxulub Impact, the asteroid impact dated to the Cretaceous-Paleogene boundary. Belongs here: a phenomenon whose primary identity is a dated event fixing a point on the geologic time scale. Does not belong here: the extinction event itself that the impact is associated with, held under Stratigraphy, where the fossil and rock record rather than the impact date is the phenomenon's own primary evidence.
