Unknown Devonian Period Fossil

I am not sure what this fossil is. It was found in Speed Quarry, Clark County, Indiana in Jeffersonville(?) Limestone. It is a Devonian Period fossil. The first picture reminds me of a stone flower with the petals radiating out. Maybe it is some sort of tube coral?  It reminds me of a Pleurodictyum cf. P. problematicum Goldfuss shown on pages 82-83 (figure 6) in the Fossils of Ohio book.

Thanks to Mary Ann for letting me photograph it.

UPDATE: I got a message from the nice people at the Indiana Geological Survey (IGS) and they write it does appear to be a Pleurodictyum problematicum. Thanks to the IGS for that information.

 

 

Bryozoan on Cornulite

This microscope image of an Ordovician Period cornulite worm tube with a bryozoan growing on it. I guess it could be the other way around with the cornulite growing on the bryozoan. It looks like the bryozoan fragment was part of a larger colony.

Fossil found in the Kope Formation of Carroll County, Kentucky.  Viewing circle represents about 3.5 mm in diameter.  Magnification at 40 times.

Leptaena Brachiopod

UPDATE: I originally labeled this Megastrophia concava but Shamalama determined it was probably a Leptaena brachiopod instead.  After some more research, I agree.

Leptaena brachiopod found in the Jeffersonville Limestone of Clark County, Indiana.  This brachiopod existed in the Devonian Period.

Thanks to Mary Ann for letting me photograph it.
