Good morning again! I found this 1.5cm gastropod yesterday over lunch in soft gray "mudstone". Haven't cleaned it or identified it yet, but the most interesting aspect is a mineralized, lined, trace fossil or actual mineralized remains of some sort of fossilized nematode. It is at the 12:00 position in the photo. The "trace" is covered by matrix to the left. Bear with me on this one Since it is in the plane of the inner shell and mineralized, I surmise the gastropod died, and as in modern world, nematodes take advantage and migrate through the tissues, eating/absorbing the detritus, but some "event" killed the nematode, or over time mineralized its "track" along the interface of the shell and the tissue. Make sense? Regardless, its really cool!!. There's another tracing in it but difficult to get any pics. Thoughts as always appreciated!!! Bone
