Hold the exact moment the world changed forever. This is an authentic soil sample directly from the historic K-T (Cretaceous-Tertiary / K-Pg) boundary layer in the badlands of Slope County, South Dakota.
Dating back exactly 66 million years, this distinct, dark geological stratum represents the fallout from the catastrophic Chicxulub asteroid impact. This single event wiped out 75% of all life on Earth, instantly ending the Age of Reptiles and closing the chapter on the non-avian dinosaurs. This sample is a literal physical cross-section of Earth's most famous mass extinction.
What is the K-T Boundary Layer? > In the early 1980s, scientists Luis and Walter Alvarez discovered a thin layer of clay all over the world that contained massive amounts of Iridium. Because Iridium belongs to the platinum group of metals that sank to Earth's core during formation, finding it in surface soil proved an asteroid had vaporized and blanketed the globe in ash.
This sample matrix was legally collected from private land in Slope County, South Dakota, with explicit landowner permission.
