Corprolite/Dino Dung Slabs

Yes these are fossilized Dino dung also known as corprolite. 2 are marked with the state they were found in. The other pieces I suspect are also Dino dung but they aren’t labeled. I’ve had these slabs since the 1990’s. These are what is used to cut cabochons for silversmithing or gold work. The pics are taken with the mineral wet as this simulates what the colours are when polished 32
