squalicorax Posted November 16, 2011 Share Posted November 16, 2011 Here is a weird echinoderm looking object. Looks almost like crinoid arms. It does not look to be composed of plates under magnification My Flickr Page of My Collection: http://www.flickr.com/photos/79424101@N00/sets Link to comment Share on other sites More sharing options...

Kosmoceras Posted November 16, 2011 Share Posted November 16, 2011 Part of a shell maybe? Link to comment Share on other sites More sharing options...
R-evo Posted November 16, 2011 Share Posted November 16, 2011 I agree. That can be a part of brachiopod shell. Link to comment Share on other sites More sharing options...
Kentuckiana Mike Posted November 17, 2011 Share Posted November 17, 2011 The one picture depicts what appears to be a cross section of the shell of an Eospirifer eudora brachiopod. It has that distinctive sine wave like pattern. Attached are pictures of a similar looking fossil fragment from a Waldron Shale brachiopod fossil.

squalicorax Posted November 17, 2011 Author Share Posted November 17, 2011 Thanks for the insight guys. I dont see brachiopod due to the mode of preservation. This objects preservation is different from that of the brachiopods i found at the quarry. Also i did not find any large Eospirifer eudora brachiopods at this quarry, only the Delthyris and the Eospirifer radiatus. Thanks mike for the look, I read your blog everyday and appreciate your fossil identification posts so much. cheers My Flickr Page of My Collection: http://www.flickr.com/photos/79424101@N00/sets Link to comment Share on other sites More sharing options...
