Nautiloidea?

[jacobwlo]

Fossil found on a beach of Baltic Sea. I'll appreciate if someone tell is that Nautiloidea or maybe other Cephalopoda?

Welcome to the Forum.

Can we get more pictures of the item from different angles/sides?

If you found that on the Polish baltic coast, then the chances are good that the rock is paleozoic, which would certainly speak for a nautilus.

Looks like an orthoconic cephalopod to me.

Almost looks like a Chondrichthyan tooth fragment. What are the dimensions of the specimen?

Could be a orthocone cephalopod or a belemnite.

Could be just what I’m used to seeing, but I think it could be a worn section of a crushed crinoid stem.

[Manticocerasman]

My toughts also go to a crinoid stem.

[Rockwood]

Orthocone seem right to me. The convex nature of the end showing what appears to be a remnant of septum is a good indication.

One would expect more contrast from the matrix and less deformation if it were a crinoid stem.

Could you take some closeups of the ends? If any pattern is visible that will help with the ID.

@Rockwood yea I saw that, but at least on my computer I can’t really tell whether or not there is a pattern or what that lighter stuff on the end is. Maybe I should have asked for better lighting on an end closeup...
