Very small cephalopod ?

[Denis Arcand]

I found this on one of my hash plate,  is it what I think it is, a very small cephalopod ?

 

[Tidgy's Dad]

I think so. 

Pretty hash plate. 

[minnbuckeye]

due to its small size, how about a tentaculite?

Tanks @Tidgy's Dad,  for once I'm finally right ID'ing my fossils 

 

Thank, your been a great help for this ID and the others.  I might not say it enough but I really appreciate what you doing

Ahem, well thank you very much, but I may not be right! 

Let's see what others have to say before I do my victory lap.

Interesting, I just look it up in wikipedia, it's the first time I hear about tentaculite.

Doesn't look like a tentaculitid to me. I'd vote for cephalopod.

Tis possible, but I don't see evidence of the rings. 

The size is about right, though. 

[ClearLake]

I also thought of Tentaculites due to the size. Unfortunately, with the sort of poor preservation, you can’t see the rings that you would expect on that so it may be difficult to tell between that and a very small cephalopod.

What are the chance of finding a cephalopod this small ?

Quite small in this formation, I should think. 

But not impossible. 

In short; I dunno. 

[minnbuckeye]

I am afraid, due to the preservation, a definitive answer will elude us. To add another possibility, how about a genal spine of a trilobite?

[Mark Kmiecik]

The level of preservation makes a hard call even harder. So far, I'm not convinced by any of the three choices proffered.

I like that possibility, in this formation I rarely see cephalopod and have never see Tentaculites, but  I can see pieces and bits of trilobite on almost all my hash plates. I think the genal spine of a trilobite might be a best bet. Unless you were joking about that ?

[Kane]

I'm not going with genal spine of trilobite with this one given what appears to be regularly spaced (albeit somewhat pitted) annulations. 

[Ludwigia]

Although the preservation leaves a lot of room for doubt, I would tend to think in the direction of the tip of a staight shelled orthocerid cephalopod.

Thanks all of you, I really appreciate all you comments

They all start out small and I have found a few pieces that include the protoconch that are that small. Love the hash plates. I can spend hours cruising them with a loupe or scope.
