This is a scarce crinoid in the Mississippian of my area, usually found here as isolated columnals (and never articulated). So I was pleased to find this group yesterday on my first 2020 trip to a favourite locality in the Durham Dales. Needs a bit of TLC and probably light air abrading (it's fragile) but not bad for a quick brush and rinse. Mississippian, Brigantian, Three Yard Limestone (shale parting), Co. Durham, NE England.

Hi All, I picked up this rock in my back yard a couple of days ago. I picked it up because I saw a couple cross sections of rugose coral and some fenestrate bryozoan fossil pieces. When looking at it later, I noticed this feature. I haven't found anything like this before. Is this just a different type of bryozoa? These little marks also look like some tiny Platycrinite crinoid pieces. This was found in Howell County, Missouri, USA. It came from the Ordovician Period. These lines measure approximately 23mm in length and measure approximately 0.79mm wide. The individual spots are oval in shape and measure approximately 0.38x0.79mm. I don't know if it shows well in the first image, but this feature appears to be in a fracture in the host rock. There is still some rock covering the feature in the fracture. Any assistance or direction that you can give me is greatly appreciated. Thanks for your time, Doug
