I've been trying to narrow down the ID for bryozoans I've been finding. I'm not sure if they're weathering out of the Bennett shale or from further up.
I have collected about 15 of these over the years and found a nice one several days ago. They are characterized by rounded form with flattish uneven bases.
Spacing between monticules is about 1 cm regardless of specimen size. The below example is about 8 cm wide at base and 5 cm tall. I can't find it right now
so can only show photos. I'll put a link below to my more recent find.
All help appreciated!
