Endolithic microorganisms in Ordovician ostracod valves

The ostracod valves irom Middle Ordovician limestones, the profile of Mójcza, Holy Cross Mts., Poland, have been found to contain a new morphologic type of microbial borings. These are phosphate fillings of tunnels (9-13 µm in diameter) parallel to the valve surface, with bottle-like terminal swellings. They occur mainly in big and smooth ostracod valves.
Key words: Endolithic microorganisms, Ostracoda, Ordovician, Holy Cross Mts.
