Own a genuine sample from one of the most important moments in Earth's history. This display features authentic soil collected from the famous K-T (Cretaceous-Paleogene) Boundary Layer—the geological layer marking the mass extinction event that ended the Age of Dinosaurs approximately 65.5 million years ago.
The extinction layer contains elevated levels of iridium and microscopic impact debris, providing some of the strongest evidence for the asteroid impact that changed life on Earth forever.
