I often find bits of Metacoceras, a Coiled Cephalopod that existed between 314 million years ago until just before the Permian / Triassic Extinction event. I have been looking for complete specimens, but typically they are bisected on some sort of sediment plane within the limestone.
In my local area, there is a lot of water. Guffy run is the major artery running through the valley and is joined by several small streams. One of the smaller of the streams is a steep deep valley tributary that runs into a tall hill. The floor is nearly completely made of shale and a limestone ledge is exposed well.
While exploring the ledge I hammered off some easy to remove edges and a piece I picked up had the shell material from this specimen on it. On the remaining rock I could see this large piece of the creature sticking out. I decided to come back with a shovel and larger hammer to remove a much larger piece of the rock.
Once I was able to get the rock back home, I took the time to split it in half. I did this to reduce the weight. In case this happens to be a complete specimen, I want to be able to work on it easily with an air scribe. The rock was very wet, and for now I am letting it dry out.
