Pseudoperna
''Pseudoperna'' is a genus of extinct very small oysters. ''Pseudoperna'' live in tight groups. This small oyster is commonly found attached in groups to the shell of large species such as ''Inoceramus''. ''Pycnodonte'' and ''Pseudoperna'' are preserved mostly as calcitic valves and are also found attached to ''Mytiloides''.〔(【引用サイトリンク】title=Stratigraphy of the Greenhorn Limestone )〕 == References ==
