Utah Gem Coprolite A+ Grade
100 - 140 Million years ago a dinosaur was roaming the tropical forests that were present in modern day Utah. That Dino had the urge to take a doo doo and through the process of petrification, this gem grade coprolite specimen was made.
These slabs feature remains of an ancient ecology and are a true piece of the Early Cretaceous period. Highly sought after in this Gem Grade state, this specimen was highly agatized making it perfect for making into cabochons, or polished specimens. We only have these 5 slabs available and after it's gone we may never receive any more of this grade material.
