Bryozoa?

I split some blocks of shale from St.Paul Indiana I collected last October and I found this. I was thinking bryozoa. It is 2 inches long and 1/2 inch wide.

Waldron shale- silurian

Looks bryozoan to me to. That would make the darker spots maculae.

I was hoping you were going to see this. Have you seen many like this from the quarry? Well, I guess it's time to go through the 49 bryozoan found in the Waldron.

Thanks everyone!

Best regards,

Very nice.:)

I would go with Trematopora tuberculata for this one. 

They are acanthopores (tubular spines), not maculae. In some more modern literature the new name for acanthopores appears to be styles, but I don't like this as much! 

If you have found any further information in the years since this post, I would be very interested.
