Last weekend our club got together in a quarry. The leader said it was primarily for mineral collection and explained few if any fossils are found in this Devonian material. He was absolutely correct and I was equally disappointed! Our club hunts typically produce both minerals and fossils. But not this quarry. Here is what I scraped up: Not too impressive for 8 hours of exploration. I did manage to also find a trilobite cephalon that I donated to a member that found a pygidium. Anyways, the minerals, unlike the fossils were plentiful, varied , and beautiful. I stumbled upon one vug that measured close to 24 inches across and was on the lower corner of a 2 ton boulder, covered with 1-2 inch crystals!!. The belt of my rock saw gave out after about 30 minutes of rock removal forcing me to leave it behind. Our leader is going to see if the quarry can pull this beast to the side and he will try to extract this wonderful specimen. When I returned home and began chipping matrix away from some of the vugs, a special treat was in store for me. A black spot showed up on the exposed layer of a specimen as I worked on it. After I exposed more of the dark area, it turns out, this quarry did indeed have an exceptional Devonian fossil. I am not sure of the identity of this tooth. So these images will also show up in "Fossil ID"
