End of the Dinosaur Era

Hold the Moment the Dinosaurs Vanished

An unassuming layer of clay holds one of the most dramatic chapters in Earth’s history—the Cretaceous–Paleogene (K–Pg) extinction event, which ended the reign of the dinosaurs 66 million years ago. Formed in the aftermath of a colossal asteroid impact near modern-day Mexico, this thin sedimentary band is found across the globe, marking the boundary between the Mesozoic and Cenozoic eras.

Rich in iridium—an element rare on Earth but common in asteroids—this clay is geological proof of the cataclysm that reshaped life on our planet. Over 75% of Earth’s species vanished, paving the way for mammals—and eventually humans—to rise.

Now, you can own a genuine sample of this boundary layer, a physical fragment of deep time. Whether you're a fossil enthusiast, a collector of cosmic history, or a lover of natural wonder, this artifact offers a rare and humbling connection to Earth's most pivotal moment. 

Our samples of this 66 million year old clay come from one of the best-preserved K–Pg transitions found in Bidart, France. The acrylic display contains a roughly 5mm sample in a clear removable jar.
