Found this cool rock

Was wondering if anyone could tell me more about this

Possibly a cross-sectional view of two orthoconic nautiloids. I'm not overly confident of it though.

You put "information" in one of your tags. We need some too, as is noted in the instructions for posting in this topic, like location and stratigraphy if known. A few more photos from different angles would also be helpful.

As this is an international forum, some location information is necessary for us to figure out what you have found.

I think orthocone may be a good guess.  I see what looks like a brachiopod imprint on the upper right, and possibly a crinoid stem piece on the lower middle/right.

Ideally everything could be identified by what it looks like. When it's not clear what it used to look like clues are needed to make an educated guess.
