Fistuliporoid Bryozoans from the Silica Shale

I'm sure I've mentioned before about how difficult it can be to ID some Bryozoans beyond the Family level. Such is the case with some Fistuliporoid Bryozoans that I've found in the Silica shale.

Some form finger like branches

Others, massive colonies

Still others colonize Brachiopod shells

Without thin sections both perpendicular and parallel to the grain of the colony, I'll never be able to truly ID these even to a genus level. So they remain within my collection simply labelled "Fistuliporoid Bryozoan".
