Scalebar Posted October 7, 2020 Share Posted October 7, 2020 I've been cleaning away at this by hand, I can't get much further as the rest of the matrix is very hard. What have I been uncovering here? I thought brachiopod shell when I just saw the edge, now I have no idea. Looking at other pics of Wenlock fossil I couldn't spot anything similar. Can anyone enlighten me? Link to comment Share on other sites More sharing options...
Thecosmilia Trichitoma Posted October 7, 2020 Share Posted October 7, 2020 It looks a crinoid stem section IMO. It is better to keep your mouth closed and let people think you are a fool than to open it and remove all doubt -Mark Twain Link to comment Share on other sites More sharing options...
grandpa Posted October 7, 2020 Share Posted October 7, 2020 Or perhaps a cistoid cup plate. 2 Link to comment Share on other sites More sharing options...

Scalebar Posted October 8, 2020 Author Share Posted October 8, 2020 Cool! I got stumped by seeing something so large and not holllow. I might see if I can get it a bit cleaner thanks Link to comment Share on other sites More sharing options...

Kentuckiana Mike Posted October 10, 2020 Share Posted October 10, 2020 I agree, it looks like a part of a fossil crinoid calyx plate. Something similar to it is found in the Silurian Period Waldron Shale (upper Wenlock) called Macrostylocrinus fasciatus (Hall, 1879). Illustration from Indiana Department of Geology and Natural History Annual Report 11 by John Collett 1881 (page 258; Plate 12 Figures 5-6).
