The 15 pages that link to K–Pg boundary, each with the reason it gives.

• Radiometric datingRelated: Radiometric dating helped establish the boundary’s age and connect it to the Chicxulub impact.

• Deccan TrapsRelated: The principal Deccan eruptive phase overlapped this boundary.

• Chicxulub craterRelated: Impact debris at this boundary links Chicxulub to the extinction interval.

• Luis AlvarezRelated: The worldwide iridium anomaly at this boundary became evidence for an extraterrestrial source.

• Chicxulub impactorRelated: Dating precision helps resolve how closely extinction unfolded after impact.

• EutheriaRelated: Debates about when placentals diversified often focus on this boundary and its aftermath.

• IridiumRelated: An unusually iridium-rich layer at this boundary helped support the asteroid-impact explanation for the extinction.

• Chicxulub impactRelated: The impact’s deposits coincide with this boundary in the geological record.

• Extinction selectivityRelated: Fossils across this boundary show abrupt, taxon-specific disappearances.

• Luis Walter AlvarezRelated: The worldwide iridium-rich layer at this boundary anchored the impact argument.

• EnantiornithesRelated: The group’s last appearance falls before this boundary.
