Crepidula was named by Lamarck (1799) [Sepkoski's age data: J Oxfo-u R Sepkoski's reference number: 122]. It is extant.
It was reranked as Calyptraea (Crepidula) by d'Orbigny (1841).
It was assigned to Calyptraea by d'Orbigny (1841); to Crepidulidae by Clark and Arnold (1923), Turner (1938), Durham (1944), Woodring (1957), Addicott (1970) and Ward and Blackwelder (1987); to Neotaenioglossa by Sepkoski (2002); and to Calyptraeidae by Martin (1904), Oostingh (1935), Wenz (1938), Gardner (1947), Moore (1976), Ladd (1982), Squires (1987), Wilson (1993), Squires (1999), Todd (2001), Wienrich (2001), Rosenberg (2005), Landau and Marques da Silva (2010) and Matsubara et al.
