K-Pg Boundary Chicxulub Riker Display Collectible

What is the K-Pg boundary Event?

The K-Pg boundary marks a massive extinction event that occurred 66 million years ago, likely caused by a CM-type carbonaceous chondrite asteroid impact that struck near the present-day Yucatán Peninsula, forming the Chicxulub crater. This cataclysmic event triggered global firestorms, a 300-foot tsunami, and an "impact winter" that blocked sunlight—ultimately wiping out 75% of Earth's species, including the non-avian dinosaurs.

The Chicxulub Asteroid Impact That Changed Earth's History

Explore one of Earth's most dramatic turning points with this scientifically curated educational collectible featuring authentic K-Pg boundary clay from Iridium Hill, Montana. This striking Riker display commemorates the mass extinction event that ended the reign of the non-avian dinosaurs 66 million years ago. Ideal for collectors, educators, and science enthusiasts, this specimen and great artwork connects you directly to one of Earth’s most cataclysmic events.

What type of asteroid caused the K-Pg Extinction Event?

A CM3 carbonaceous chondrite meteorite—similar to the renowned Murchison meteorite—struck near today’s Yucatán Peninsula about 66 million years ago. As it streaked through Earth’s atmosphere, the meteor’s bright trail lit up the sky, breaking apart in a brilliant aerial fireball. Upon impact, it triggered immense shockwaves, global wildfires, and a towering tsunami over 300 feet high. Ejected debris blocked sunlight, causing a prolonged “impact winter” that led to the extinction of over 75% of all species on Earth, including the dinosaurs.
