I pulled this one out of a creek bed a couple weeks ago but cant narrow it down. Any ideas?

Its from the Georgian Bay fm (Upper Ordovician)

 

Forgot to add: the specimen is ~5cm/2 inches in length

Although there are some bryozoans that can be identified to genus or even species based on external features (monticules, etc.) I suspect it's going to be difficult to get beyond Ectoprocta (bryozoa) without sectioning and careful examination of the internal structure.   Here is a link on making acetate peels.

Judging by the shape, the exterior pores and the interior structure, I'm thinking stromatoporoid, but I could be miles off base
