New Members Mastic Posted August 25, 2023 New Members Share Posted August 25, 2023 I found this plate of Ordovician limestone in Prince Edward County, Ontario. It’s a relatively unremarkable specimen, bits of crinoid stems and brachiopod shells are scattered throughout, but it contains a prominent raised convex bar seen on the upper left of the specimen in the first image. My best guess is that it’s an ichnofacies of some kind, a burrow or trail left by something like a trilobite. I’ve included some close ups of the bar, there are small bits of shell where it comes to an end. Any help identifying it is greatly appreciated! 1 Link to comment Share on other sites More sharing options...
Mark Kmiecik Posted August 25, 2023 Share Posted August 25, 2023 Intriguing. I don't have a clue. Let's wait for others to chime in. 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them! Link to comment Share on other sites More sharing options...
