Complete newbie with a bunch of new fossils so brace yourselves. The fossil was found in east Clare (Ireland) Waulsotian limestone. This rock is dated Tournaisian - Lower Visean, and is a mix of solid limestone & a brittle lime mud. (Id'd using geological survey maps) "Waulsortian limestone is extensively developed in Ireland, and it represents a phase of submarine bank development during the Tournaisian (Mississippian, Carboniferous). These carbonate buildups are rich in (now lithified) lime mud, contain a shelly marine fossil fauna and generally lack any sign of a rigid supporting framework." Murray, John & Henry, Tiernan. (2018) Lots of crinoid, bryozoan and brachiopod fossils found a round it. It appears to be a part of a longer section (unexcavated). I wasn't able to find anything online that resembled it so would be delighted if anyone could steer me towards an answer. Thanks!
