To me, it looks like a very worn imprint from a rugose coral.

Looks like an impression of a Spirifer Brachiopod; probably Devonian in age.

Close to this uncrushed shell.

I had considered a spiriferid brachiopod, but the lack of any beak or sulcus kind of threw me.

Plus, the imprint seems to be angled in towards the rock, which I wouldn't expect from a brachiopod, but would from a horn coral.

We may not be able to narrow it down as the specimen is so water worn.

Mmmmmm... we seem to be in the Cambrian to Devonian age.

Stand back, opening view portal... found something familiar, but had to go to Carboniferous period.

Hey, that Zaphrentis looks familiar... see the radial septa along that line? It might not be a Zaphrentis, but that is a clue we can follw when we get back to the proper space time.

There, we're back. Everybody OK? Except that guy back there who lost his hat in the Devonian, I think we all made it OK.

I think the coral people might be right. I saw some zig-zag patterns on the second photo. That would rule out Brachiopod and enter rugose septa marks as a possibility.
