Based on the WV geological map mentioned in Anonymous's post, these are Devonian formations.<br /><br />DavidUnknownhttps://www.blogger.com/profile/13170336477902973540noreply@blogger.comtag:blogger.com,1999:blog-3927143376177050152.post-45092846559156874292010-04-02T07:05:33.292-04:002010-04-02T07:05:33.292-04:00Howard, I agree that most of the county where the ...Howard, I agree that most of the county where the fossils are found is underlain by Mississippian rocks, the area that the fossils were found in (Border of VA/WV) is Devonian in age, specifically the Chemung Group. After further research I think the first and fourth are Spinatrypa but stand by the Productella ID for the second and third.Shamalamanoreply@blogger.comtag:blogger.com,1999:blog-3927143376177050152.post-77734836906683599482010-04-01T00:31:25.442-04:002010-04-01T00:31:25.442-04:00Thanks Shamalama and Howard for the identification...Thanks Shamalama and Howard for the identifications and site info. I was wondering if the last brachiopod picture might be from the Mississippian period. It looks like a brachiopod found in area within sight of metro-Louisville called Floyd Knobs and the hills that stretch out to Borden, Indiana. The fossil might be called <a href="http://www.museumcollections.in.gov/detail.php?t=objects&type=all&f=&s=brachiopod&record=220" rel="nofollow">Orthotetes keokuk</a> (click link to see specimen at Indiana State Museum).Michael Popphttps://www.blogger.com/profile/16741723962997816729noreply@blogger.comtag:blogger.com,1999:blog-3927143376177050152.post-80807034712025519912010-03-31T13:41:58.800-04:002010-03-31T13:41:58.800-04:00According to a geological map of WV (available her...According to a geological map of WV (available here: http://www.wvgs.wvnet.edu/www/maps/maps.htm), most of Monroe Co. WV is underlain by Mississippian rocks, which fits with my (and Shamalama's) identification of the second and third photos as productid brachiopods. The little elongate dimples (or bumps) all over the shell surface are spine bases, and these are very characteristic of some of the productid brachs, which are common in Mississippian rocks (even here in the Alberta Rockies).<br /><br />Cheers,<br />--HowardAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-3927143376177050152.post-14062055649205026732010-03-30T07:04:44.032-04:002010-03-30T07:04:44.032-04:00Hmmm. hard to nail down the location with the vaug...Hmmm. hard to nail down the location with the vauge info he gave you, so I'm not sure of the age, but I think they are late Silurian to Devonian fossils. The first and fourth looks like Atrypa sp. Second and third look like Productella. Not sure what the last one is.Shamalamanoreply@blogger.com
