Possible Huge Bryozoan/Anthozoan

[CSimpson176]

Hello all! I was hunting for fossils in Owingsville, KY on a road cut that contains the Drakes Formation (Late Ordovician). Plenty of brachiopods, small bryozoans, cephalopods and other common Ordovician fossils found. I happened upon this piece, at first just thinking it was geologic with some bryozoan encrusting/deposited within the rock. I almost left it behind but couldn't help but wonder if it was all one piece and that it may truly be an example of large bryozoan or coral. I was curious as to what you all think, whether it be one of the two, mostly geologic or what have you.

Interestingly has white calcite on the top left and brown calcite on the right.

First photo is the bottom, second from the side and the third is from the rear (in contrast with the very first photo I had uploaded). Final photo shows some surface texture which tells me that either it is bryozoan encrusting or shows that this could be one whole bryozoan colony (maybe?).
