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]
