New Members MissouriBeginner Posted July 8 New Members Share Posted July 8 I see crinoids. Is there anything else? Is the curved moon shaped thing a bent crinoid? What about the triangle thing is that a crinoid top? Also can anyone tell me anything about the age or type of this limestone ? It is very bright white. 1 Link to comment Share on other sites More sharing options...
JBkansas Posted July 8 Share Posted July 8 (edited) Can you give us the county/city of your find?

Rockwood Posted July 8 Share Posted July 8 I think the curved moon may be a gastropod. Platyceratid gastropods are sometimes associated with crinoids, but that doesn't count as an ID. 1 Link to comment Share on other sites More sharing options...

It was with gravel so it may have been brought in from a quarry in a county nearby Link to comment Share on other sites More sharing options...
JBkansas Posted July 8 Share Posted July 8 (edited) I think the donut at the top may also be a crinoid disk. Crinoid disks can be > 1 inch across and it looks like the donut is smaller than that (though I can't rule out gastropod). The triangle thing could be a crinoid spine (or a broken piece of nearly anything). Edited July 8 by JBkansas 1 1 Link to comment Share on other sites More sharing options...
