Tentaculites vs nautiloid id

[Mainefossils]

This is a another specimen from the Leighton Fm, Maine, Silurian. I uncovered it a while ago, and at first thought that it was a crinoid stem. On second look, though, I realized that the segments on the "stem" were curving inwards, instead of outwards. Furthermore, what I first that was the stem fading into the rock was actually the width and depth decreasing. I am torn between a Tentaculites sp., which is not known specifically from this formation but shows superficial resemblance to this specimen; and a small orthocone nautiloid, which is known from this formation. Any help on its id would be appreciated. Here are some pictures of it:

That looks like Tentaculites to me which reached its greatest abundance in the late Silurian.

I agree, that's a Tentaculites, whatever the books might say. ,

Do tentaculitids ever have their ribs on a slant? (I can't find any images with a quick search). Nautiloids often do.

I have hundreds of these but they don't get stored where they are easy to find in this cold dark hole of misery called Maine.

It does definitely strike me as an example of one however.

P.S. I'm retiring. Where should I move to ?

Edit: Tentaculitid is my thought.

Thanks for all the replies! I was hoping it was a tentaculite.
