Pseudoperna is a genus of extinct very small oysters. Pseudoperna lived in tight groups. This small oyster is commonly found attached in groups to the shell of large species such as Inoceramus.[1] Pycnodonte and Pseudoperna are preserved mostly as calcitic valves and are also found attached to Mytiloides.[2]
