Collection: The Extinction Horizon: The 66-Million-Year-Old K-T Boundary Specimen

There are moments in geological history that are measured in eras, and then there are moments measured in a single afternoon. This specimen represents the latter. Sourced from the badlands of Slope County, South Dakota, this matrix sample captures the precise boundary layer where the Cretaceous period abruptly ended, and the new world began.

To hold this soil is to hold the physical residue of Earth’s most transformative apocalypsethe day the non-avian dinosaurs vanished forever.
