    By the end of the Mesozoic, dinosaurs had ruled the Earth for 175 million years, evolving into innumerable forms across the years. All that ended with a six-mile-long asteroid that wiped out all non-avian dinosaurs in one fell swoop.

    Evidence of this impact can be found in a globally distributed strip of iridium, an element brought to Earth by the asteroid. This specimen is a collection of material from this K/Pg Boundary geologic layer, a relic from the end of the Age of Dinosaurs. The geologic sample has been cast in resin and affixed to an informational card with the Mini Museum Seal of Authenticity.

    You deserve better than craft store science products. And we think learning is more impactful when you're holding a tangible piece of what you're learning about. That's why Stemcell exists.

    With every new product launch, our list of new ideas gets longer rather than shorter. So check in often for our latest projects, and thanks for being a part of our endeavor to make the world a smarter place to live.
