Strange fossil rock, worth keeping?

[kingpotatoman]

Sense in new to collecting fossils I need to know what is worth keeping and what isn’t, I have this one rock that just has a few shells but some are unique, could anybody tell me what this is and if it’s worth keeping?

I don't think anyone can really tell what is worth keeping and what is not. It very much depends on what you want to collect. If they provide you with interest and joy, that in itself makes it worth keeping. Whether or not they are common is not even a great criterion, as there are very common species that are beautiful and interesting to have in one's collection.

Kane said it all, so I won't be repetitive. Looks like you have some brachiopods and a gastropod imprint there.

Hello, and a very warm welcome to TFF from Morocco! 

Some interesting bits of brachiopod and a gastropod external mold. 

I'd keep it for one.

Welcome to TFF! Seems like others beat me to it. The only things worth keeping are the things you think are worth keeping! (On that note, I too see brachiopods).

I would keep it. Welcome to the Forum !
