Brach3 posted a topic in General Fossil Discussion
Dear all, if Devonian Epizoans (Epibionts) & Pathological Brachiopods (all the periods) are a fascinating group of fossils for you and you want to discuss anything about their paleoecology, please post your photos (specimens) in this thread.- 225 replies

Found this piece of large (for the location) orthocone yesterday in a Brigantian (Mississippian) mudstone. The thin bits of surviving shell are apparently pierced through with many small round objects, mostly circular, 0.3 - 0.5 mm in diameter. Each one is now a very low cylinder (like a watch battery) with apparently vertical sides and depressed centre. Many are filled with pyrite. They have left impressions on the mudstone internal mould - the whole shell fossil is covered with them, both the living chamber and chambered phragmocone. Ostracods came to mind but these seem to go right through the shell and the spacing is quite regular so was whatever they were growing there? Orthocones and many other types of shell are common from this location but I've never seen this before. And one more:
