Beekite Covering Fossil

This picture shows ring patterned concretions of calcite on some sort of fossil.  I picked it up because of the patterns but after looking at it closely I am curious as to what kind of fossil this is. 


The piece is about 4- 8 cm long.

Mindat.org describes beekite as "a name given to chalcedony pseudomorphs after coral or shells."

I'm going to go out on a limb here and say it might be fish bone. Hard to say for sure because of the Beekite covering but the granular surface beneath it looks like bone to me. The size is a little large for most shells of the period, unless it's a coral or bryozoan. Can you seen any more detail up close?

Thanks for the comment.

That rock is used as a weight in field I grow watermelons at so when I plant them this weekend, I will bring that rock back home. That would be really nice if it is some sort of fish.
