The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous–Paleogene Boundary

evidence

Supports the multi-author synthesis position that the Chicxulub impact was the proximate cause of the K–Pg extinction, and the global distribution of the boundary layer with its shocked quartz and spherules. The Deccan Traps alternative continued to be argued after this review; that literature is not cited here. V55 verification basis: this session had no network access to any source — WebFetch was egress-blocked and the WebSearch budget was exhausted — so the cited work was not retrieved and its pagination was not re-checked. Volume and page range are quoted from standing knowledge and were not re-checked.

A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
