Middle Devonian Mahantango Formation ID Requested

Recommended Posts

New location, still in Eastern Panhandle WV.  One picture has the tip of a pencil so you can see size.  The circled part...I am not sure.  Are the shells brachiopods? I see some crinoid stem in there.  Thank you for your insights.

Yes, a variety of brachiopods and crinoid ossicles, the circled piece is most likely a fragment of a larger brachiopod.

Agreed. I've found pieces of larger shells like this before. The shells appear to have been rather thin and the ridges show a rather sloppy pattern.

Little Chonetes sp and larger Protoleptostrophia, I think. 

Agreed but more correctly they are Devonochonetes sp. and are very common in the Mahantango formation in certain beds.  The larger circled fragment is possibly from a Protoleptostrophia perplana or a Devonochonetes coronatus.  Examples from the Mahantango in Pennsylvania on my blog: http://viewsofthemahantango.blogspot.com/2010/06/chonetesdevonochonetes.html
