Fossil Block Experience Kit — Green River Formation | Fossil Butte Member
Uncover millions of years of prehistoric history right in your own hands. Each kit includes an 8–9 lb. block of authentic Fossil Butte Member rock sourced from the renowned mini fish stratification layer — one of the richest fossil-bearing zones in the Green River Formation.
What's Inside Your Kit
Every Fossil Block Experience Kit includes everything you need to get started:
- 8–9 lb. block of genuine fossil-bearing rock
- Sturdy display stand for safe splitting
- 8-inch splitting shim
- Fossil identification booklet
What You Might Find
This material comes from a layer with the highest concentration of fish fossils, making every split an exciting discovery. While no find is ever guaranteed, most blocks yield at least one fossil — commonly fish remains, scales, and insects, with the occasional leaf or other rare specimens.
How It Works
Split your block down gradually — the thinner the split, the better your chances of uncovering something remarkable. Here's where it gets exciting: if you reveal a great find mid-block, you can choose to keep it as-is or keep splitting to see what else may be hiding inside. The choice is yours.
Every block is unique. Every split is a surprise.
