Robert Mahorney Posted March 7, 2021 Share Posted March 7, 2021 Brachiopods orthoceras crinoids all found right here in Hendersonville TN Sumner county just north of Nashville. Love to fossil hunt and see what I can find while imagining worlds of the past. 3 Link to comment Share on other sites More sharing options...

I don't think these are Orthoceras. Orthoceras is a genus that is only found in Sweden and the Baltic states, not in the US Link to comment Share on other sites More sharing options...
Robert Mahorney Posted March 11, 2021 Author Share Posted March 11, 2021 Oh ok thanks. So what do u think they are. I mean I know they are cephalopods but does anyone know their specific genus or species. They were found in limestone at about 600 feet elevation in Sumner County Tennessee Link to comment Share on other sites More sharing options...
erose Posted March 11, 2021 Share Posted March 11, 2021 "Orthoceras" had become a common catch-all or garbage bin name for many orthoconic cephalopods. Older literature would often list species of Orthoceras for North America. They have all been placed in different genera over the years. But there are many genera and species of straight shelled, orthoconic, cephalopods in our North American Paleozoic stratas. You need well preserved specimens, good reference books and an idea of what species would be found in the formation you are collecting to get an identification of any value. Here is a great link and resource that may get you further along if these are Ordovician in age: http://strata.uga.edu/nashville/index.html 1 Link to comment Share on other sites More sharing options...
