Concavodontinae is an extinct subfamily of prehistoric bivalves in the family Praenuculidae.^[1] Concavodontinae species lived from the middle Ordovician, Caradoc epoch through the late Ordovician Ashgill epoch.^[2]^[3] Concavodontinae fossils are found in Europe and South America,^[4] and species are thought to have been stationary attached to substrate in shallow infaunal marine water environments where they formed shells of an aragonite composition.^[2] The subfamily Concavodontinae was named by Teresa M. Sánchez in 1999.^[4]
