I got hold of the Mehl Silurian Michelinoceras paper and here are some pictures of radulae from the paper.

Just one more picture from the Mehl paper - the supposed pair of tentacles. I wonder if these could be trace fossils since there seem to be some other horizontal burrows on this bedding plane.

Cool! I had a feeling you would come up with that paper. I really wanted to see the pics. of the as you put it "supposed tentacles". I'm definitely not an expert on these things but (without seeing a closer view) I agree they do "appear" to be conveniently placed burrows. Still intriguing....one of my dreams to find some sort of tentacle trace.

A little disappointing isn't it? I've seen the paper referenced as saying that there are ten arm impressions, but actually it says that two large tentacle impressions are in evidence and that an eight-armed plus two-tentacled ("10 Fangarme") beast is plausible. Keep looking !

.. and I'll keep looking too!

I will! They've got to be out there somewhere....
