Help ID radial pattern

Hello, 

I found this rock this morning behind my house and I'm drawing a blank as to what it could be. There are lots of brachiopods, bivalves and gastropods in this particular area but nothing that matches this. It kinda looks like an end view of a coral but I only find those about a mile away and not preserved like this. Any ideas would be appreciated. Thanks for looking.

Maybe a rather weathered fenestellid bryozoan? There seem to be cross connections as well as branching.

 

A nicely centred specimen - I know I've seen them like that before but can only find this image on a quick search:

Yes, +1 for fenestellid colony.

That's a very good possibility! I can now see the evenly spaced bumps where the cross connections could be. Thank you.

I agree, thank you.
