Odd unknown bryozoan from the Kalkberg formation of New York

I found a number of small pieces of a very small celled Bryozoan that are preserved with a darker colored Calcite than some other fossils found in the Kalkberg formation. They look a little tumbled which makes me wonder if they were washed in from a different area.The fact that only small pieces are found lends some evidence to this hypothesis but it may be that I have just not found an intact specimen, only fragments that weathered out of the rock.

Specimen #1

Specimen #2

Specimen #3

These specimens were found in a roadcut near Schoharie, New York from the Kalkberg formation (Devonian, Lockhovian to Pragian stage).
