Tessy Posted October 21, 2012 Share Posted October 21, 2012 (edited) I went to Fossil Park in OH hoping to find Bryozoa and I think I might have, what say you? Could the dots in the center left of my 3 inch hash plate be part of Stenopora? And the stuff to the upper right be Leioclema? I think Fossil Park is Middle Devonian, correct? This is the link that I was using as a guide http://www.isgs.uiuc.edu/maps-data-pub/publications/beg-fossils/plate-04.shtml Edited October 21, 2012 by Eli 1 Link to comment Share on other sites More sharing options...
Tessy Posted October 21, 2012 Author Share Posted October 21, 2012 This might be a better pic...if darker. Link to comment Share on other sites More sharing options...
araucaria1959 Posted October 21, 2012 Share Posted October 21, 2012 I agree with bryozoa, but cannot say about the genus. There is also a brachiopod (spiriferid). araucaria1959 Link to comment Share on other sites More sharing options...
paleostone Posted October 21, 2012 Share Posted October 21, 2012 In addition bryzoa and brachiopod fragments, there is something else - like a sponge or some armor - the one with the dots ... in my country like brachiopods, are determined on Silurian period ...

araucaria1959 Posted October 21, 2012 Share Posted October 21, 2012 Is the cross section of this enigmatic piece (where it is broken) calcitic like an echinoderm? Otherwise, one can consider the possibility of fish armor in the middle devonian. araucaria1959 Link to comment Share on other sites More sharing options...
squalicorax Posted October 21, 2012 Share Posted October 21, 2012 I agree with bryozoa, but cannot say about the genus. There is also a brachiopod (spiriferid). araucaria1959 Its likely the orthid brachiopod Vinlandostrophia My Flickr Page of My Collection: http://www.flickr.com/photos/79424101@N00/sets Link to comment Share on other sites More sharing options...
araucaria1959 Posted October 21, 2012 Share Posted October 21, 2012 The brachiopod does in fact look like Vinlandostrophia: http://www.google.de/imgres?q=Vinlandostrophia&num=10&hl=de&tbm=isch&tbnid=uMtt9ypcBkD4IM:&imgrefurl=http://viewsofthemahantango.blogspot.com/2011/12/vinlandostrophia-biforata-from-verulam.html&docid=HySA_qXgrwCUOM&imgurl=http://2.bp.blogspot.com/-jiaB8Hw90qA/TtdqiKl9TEI/AAAAAAAAEA4/oeCmkxalhW8/s1600/IMG_6813.jpg&w=1024&h=768&ei=UwWEUO77JsXXsgaUxYGQDA&zoom=1&biw=1246&bih=857&iact=rc&dur=188&sig=115305578462837720505&page=1&tbnh=156&tbnw=208&start=0&ndsp=22&ved=1t:429,r:5,s:0,i:87&tx=87&ty=81 but the specimen we are discussing here was said to be from the middle devonian (but I don't know whether this is correct). If so, I would prefer a spiriferid, possibly Mucrospirifer. On the other hand, if it's ordovician, Vinlandostrophia sounds very plausible. In fact, with regard to lithology, the stone really looks like some Verulam material I have. So I think it is important to get sure about the age of that specimen. araucaria1959 Link to comment Share on other sites More sharing options...
squalicorax Posted October 21, 2012 Share Posted October 21, 2012 (edited) There are 3 fossil parks in Ohio. If it was the one in Toledo/Sylvania then it is Middle Devonian Silica Shale at the Oleander Park but if its or one of the various ones in the Cincinnati Area its likely Ordovician.

Tessy Posted October 22, 2012 Author Share Posted October 22, 2012 (edited) @squalicorax. Oops, sorry, I found the specimen at Sylvania Ohio's Fossil Park. http://www.olanderpark.com/pages/Fossil.htm Thanks everyone.

squalicorax Posted October 22, 2012 Share Posted October 22, 2012 It is Mucrospirifer then. My Flickr Page of My Collection: http://www.flickr.com/photos/79424101@N00/sets Link to comment Share on other sites More sharing options...
Tessy Posted October 23, 2012 Author Share Posted October 23, 2012 @araucaria1959. Could you expound about echinodems...i have no idea if there might be any in my hash plate, it would be cool if there is. I'm looking at this guide - http://www.isgs.uiuc.edu/maps-data-pub/publications/beg-fossils/plate-17.shtml I'm not sure what calcitic means, i'll look it up. And i'm learning about Placoderms I'll try to post better pictures after I clean it some more. Thanks very much. Link to comment Share on other sites More sharing options...
