Catalog Number: CG-0100
This Solenochilus, an extinct genus of paleozoic cephalopod, was found today (Late August 2020) after splitting a piece of float limestone half-buried in the mud at creek level upstream in Guffy Run. The rock was three inches thick and had a long rectangular shape. A heavy blow to the center of the rock revealed roughly a third of the Solenochilus specimen, as its steinkern separated from the shell.
The plan is to prep this further. Hopefully, I will have more to write about it at that time.
I’ve put a couple of hours into this. The shell is chipping away slowly. At times I get larger areas of shell, but it’s very dry and brittle and eventually shatters. The steinkern will likely be very good-looking, so I’m aiming to expose that fully. I am using a combination of the CP-9361 air scribe and a grinder with a concrete wheel to remove the matrix.

After lots of work, this is where I landed a few days later. The back still needs to be worked on. There is still shell material that can be worked on and more of the body chamber can be exposed. I’m not sure about the underside of the specimen, I may give it a shot. These seem to end up on the seafloor and get ground down, perhaps with water motion. You can tell that the shell itself has tilted perhaps 10 degrees off-center compared to the layers within the limestone.
