Bryozoan guesses

[minnbuckeye]

I occasionally pick up a few bryozoan when hunting for "fossils", but they must have something about them that are intriguing. These two specimens caught my eye and  were collected from a road cut in southern Indiana. There is Kope overlain by Belleview, Ordovician. After studying possible bryozoan that match, I am not sure of an ID. So let me know your thoughts.

The second one looks like a branching form of Constellaria

@Northern Sharks, that was my gut instinct, but everywhere I searched, it said Constellaria is rare in the Kope. If it is rare, I like the specimen even more!! Thanks for your thoughts.

Looks like Constellaria to me. I’m not familiar with their prevalence in the Kope formation, but this paper may help.

The other one looks like Parvohallopora subnodosa to me.

One possible species listed for the Fulton and one in the Clays Ferry.  You certainly have a rare specimen.

I know bryozoans can be hard to ID without thin slicing. I just wanted some gut thoughts from members more knowledgeable than me, which are most of you are. Thanks for all the comments!!! Just what I wanted.
