Hello all, This strange fossil is from the Platteville of Beloit Wisconsin and I have no idea what it is. It is fairly well preserved with a fine granular texture to it. Any ideas are welcome!

So this is a fossil from Beloit Wisconsin found in the Platteville formation. I am pretty sure it is a cephalopod but I have no idea what genus or species. The siphuncle is hollow except for two septa that run right through it. 3" post-it note for scale.
