Old Church Formation

February 07, 2023

The Old Church Formation is a geologic formation in Virginia and possibly Maryland. It preserves fossils dating back to the Oligocene epoch of the Paleogene period. It rarely exposes on land and is under-studied. However, deposits from this period are rare and the Old Church Formation likely contains many scientifically significant taxa. Ward (1985) recommended placing this formation in the Chesapeake Group.[1]
