Ramanessin odd fine please help

found this today,have no clue what it is.....any help.........in the hollow center it has crystals ..

It looks like a partial brachiopod. The coiled structure is the brachidium.

ill also add that its not Cretaceous.  Likely a Devonian glacially transported cobble.

This is what immediately came to my mind as well.  That would be a bucket-lister for me.  I still haven't found a brach with a preserved brachidium yet.  Congrats @brad hinkelman!

awesome thanks

does anyone know is a preserved brachidium common?  rare ? and the quartz crystals inside is that fossilized soft tissue maybe?

[Al Dente]

An articulate brachiopod's brachidium is made of calcite so it is not unusual for it to be preserved. It is the soft lophophore that is rarely preserved.

thank you so much for the info....

The crystals are most likely calcite crystals.

It is common for crystals to grow in hollow spaces within rock.

I agree with the above, it definitely appears to be a brach, and it is quite common to find them with calcite crystals inside of them. The same thing happens with corals, and even enrolled trilobites.
