Order Modiomorphoida Newell, 1969

Remarks.—The order Modiomorphoida was originally proposed by Newell (1969) for extinct Paleozoic marine bivalves. The group was treated thereafter under the Pholadomyoida (e.g., Fang and Morris 1997; Kelly et al. 2000, Griffin and Pastorino 2006) or Carditoida (e.g., Chavan 1954, 1969; Newell 1957; Nevesskaja 2009). Bouchet et al. (2010) placed the superfamily Modiomorphoidea under “order uncertain”, but following Bailey (1983) we here place the superfamilies Modiomorphoidea and Kalenteroidea in the order Modiomorphoida , pending further investigations. As here considered, the order Modiomorphoida was diverse in the Paleozoic, but decreased in importance through the Mesozoic, with the last representatives reported from the Neogene ( Kelly et al. 2000; Griffin and Pastorino 2006).
