JamieLynn Posted July 2, 2022 Share Posted July 2, 2022 +1 for Rugose coral. Also, when posting in ID, please include location (general, doesn't have to be specific, but at least the state/country and preferably county) and geological formation (if you know it). This is a worldwide forum and in order to help, we need a little help from you! 1 www.fossil-quest.com Link to comment Share on other sites More sharing options...

If you look around in any exposed sandy areas you'll find lots of them. 1 Mark. Fossil hunting is easy -- they don't run away when you shoot at them!

IsaacTheFossilMan Posted July 3, 2022 Share Posted July 3, 2022 Quoting myself from a few minutes ago: Quote You appear to have a fossilised coral belonging to the extinct order(*1) Rugosa. Known as the rugose corals, sometimes referred to as horn corals, they existed for ages, from the Palaeozoic ~480mya (480 millions of years ago/old) to the Late Cretaceous(**2) ~70mya. (*1): It is still heavily debated over whether Rugosa is an order or subclass, a paper by Brownlaw and Jell, 2008 stated that it should be a subclass (I can't seem to find more recent opinions, but I know there are lots) (**2): Order Stauriida is the only sub-taxa to contain members dating back to this recently - Cystiphyllida has members from the Early Jurassic (~190mya), but the vast majority went extinct at the end of the Permian, ~265mya. Same information, same ID! You have an internal mould of a solitary rugose coral from the Ordovician (485.4-443.8mya (millions of years old / ago)) of Wisconsin. Most likely candidate for this specimen is Streptelasma sp., known from SE Wisconsin - see image attached: From the collections of the Paleontological Research Institution (PRI) New York. Specimen catalogue number is PRI76805. Isaac 1 ~ Isaac; www.isaactfm.com "Don't move!
