Dagnachonetes supragibbosus brachiopod from Poland

This next fossil is also from the Skaly beds near Kielce, Poland and I think it's Dagnachonetes supragibbosus. I base this from pictures that I've found on Polish language web sites like http://www.redbor.pl/skamienialosci/0_dewon.htm and http://www.skamielinyjm.entro.pl/dewon_srodkowy-68-p.html and from the publication "Middle Devonian Brachiopods of the Bodzentyn Syncline", Palaeontologia Polonica-No. 17, 1966, plate XIV.

Devonaria zeuschneri brachiopod from Poland

Based on pictures that I've found on Polish language web sites like http://www.redbor.pl/skamienialosci/0_dewon.htm and http://www.skamielinyjm.entro.pl/dewon_srodkowy-68-p.html and from the publication "Middle Devonian Brachiopods of the Bodzentyn Syncline", Palaeontologia Polonica-No. 17, 1966, plate XVI, I'm calling this fossil Devonaria zeuschneri. It looks similar to Douvillina but the radial ribs are much coarser.

A few corals from the Skaly beds of Poland

Also included with the lot of fossils from the Skaly beds were a few corals. I can't seem to locate much English language literature that would help to ID them unfortunately.

Specimen #1
This fossil reminds me of an Eridophyllum sp. type coral. The calice is crushed so I can't really see a cross section. 

The next two specimens are solitary rugose corals
Specimen #2


Specimen #3

And finally we have a couple of nicely detailed Calceola sandalina specimens.
Specimen #4



Specimen #5





All the above specimens come from the Skaly beds (Devonian, Eifelian to Givetian stages) near Kielce, Poland.

Spinatrypa aspera brachiopod from Poland

I immediately recognized these next shells as a Spinatrypa sp. when I first received them and further research points to S. aspera. They come from the Skaly beds (Devonian,  Eifelian to Givetian stages) near Kielce, Poland. Compare these to the specimens I've found in the Windom Shale or that come from the Lime Creek Formation.

Epibonts on crinoid stems from Poland

As part of the fossil lot from the Skaly beds, that I purchased on E-bay, there were some Crinoid stem sections. Upon closer examination of some of the pieces I noticed evidence of Epibont attachments. The first three specimens appear to be Crinoid hold fasts or Bryozoan attachment bases.

 Specimen #1




Specimen #2



Specimen #3

Specimen #4 - This specimen has some "dimples" in it which might be the trace of a boring sponge.

Specimen #5 - This one is noteworthy because it has two epibonts - A Bryozoan and a possible Crinoid holdfast.

All the above specimens come from the Skaly beds (Devonian, Eifelian to Givetian stages) near Kielce, Poland.

Douvillina interstrialis brachiopod from Poland

Douvillina is a genera of Brachiopod that I only recently recognized in fossils that I was finding. It started with specimens from the Ludlowville and Widder formations and then I received some specimens from Iowa. Now I have specimens of Douvillina interstrialis from the Skaly beds of Poland for comparison.

Leptaena analogaeformis brachiopod from Poland

A very common brachiopod genera here in the US is Leptaena and it appears to also be common in the Skaly beds of Poland. Below are specimens of Leptaena analogaeformis with both internal and external views available.

Interior of Pedicle valve
Anterior - Note the slight twisting of the shell. I'm not sure if that is the result of how the shell grew or geologic processes.
Profile
Another view of the interior of the Pedicle valve with the muscle scars.

Compare that to the interior of the Brachial valve - Note this is a separate specimen and was not found articulated with the previous specimen.

Unfortunately I don't have any specimens with both valves articulated. Both specimens came from near Kielce, Poland. The Skaly beds are dated to the Middle Devonian ( Eifelian to Givetian stages).
