Genus Silurocypridina Perrier, Vannier, and Siveter, 2011

Type species: Silurocypridina retroreticulata Perrier, Vannier, and Siveter, 2011 . Upper Silurian of France .

Species included: Silurocypridina variostriata Perrier, Vannier, and Siveter, 2011 and Silurocypridina calva Perrier, Vannier, and Siveter, 2011 .

Remarks.—Some of the Silurian myodocopid material from Europe that was provisionally referred to as “Cypridinid” and “cypridinid-like” by Siveter et al. (1987, 1991), an assignment supported by Kornicker and Sohn (2000), was subsequently assigned to Silurocypridina ( Perrier et al. 2011) . The tiny crescent-shaped adductor muscle scar of Silurocypridina is similar to that of the Silurian myodocope Calocaria but has no counterpart in other fossil or extant cypridinids. The simple dome-like valve morphology of Silurocypridina is similar to that of several late Palaeozoic and Mesozoic myodocopid genera (see Kornicker and Sohn 2000; e.g., Eocypridina Kesling and Ploch, 1960 , see Wilkinson et al. 2004). Without information about their soft-anatomy, the classification of such relatively featureless cypridinaceans will remain unresolved.

Stratigraphic and geographic range.—Upper part of the Silurian; France, Czech Republic, England, Wales, Poland, and possibly Sardinia (see Perrier et al. 2011, 2019).
