Is this a type of Coral or something else?

[Plantgrogu]

Found near Cayuga Lake on the bank of a tributary. The raised spherical type shapes measure 3 - 4 mm in diameter and can be seen on several sides of the stone. I'm not sure what the matrix is but think it's a type of shale. There are so many types of shale in my area and I have yet to learn how to discern between them. This stone is very hard, dark grey (not quite black) and cannot be fragmented/chipped easily like others I find that can be crumbled in my bare hands. Could this be a coral? My field guide for this area doesn't show any corals that resemble this. I love this one!

I would guess encrusting bryozoan on this one.

Nice! My first! For some reason I thought it was too big for bryzoan. Will read up on this. Thank you

Maybe(LikeTim said) a (e.g. fenestellid) bryozoan

Thank you for sharing!! I find this so fascinating! Being in an area of glacial deposits, I am always wondering what has been found in formations to the north that could have been brought here.  This is good stuff!

Wait, what? There is a whole journal for Atlantic geology?!?! This paper is pure gold including the bibliography.

I have found my tribe at TFF. 

THANK YOU!

yeah,and with a very reasonably (if not totally) complete archive of back issues

edit: there is some emphasis on the Canadese Maritime Provinces
