摘要：
In the Volkhov Formation (Lower Ordovician) of Leningrad district a whole shell and some isolated valves belonging to genus Philhedra (order Craniida) were found. The dorsal valves consist of carbonate calcium and ventral valves - from phosphate calcium. Last ones were built probably by organic matter in life and were phosphatizated after death.
