Macoma
Taxonomy
Macoma was named by Leach (1819) [Sepkoski's age data: T Ol-u R Sepkoski's reference number: 1112]. It is extant.
It was reranked as Tellina (Macoma) by Johnstrup (1882); it was reranked as Gastrana (Macoma) by Abrard (1947).
It was assigned to Tellina by Johnstrup (1882); to Gastrana by Abrard (1947); to Veneroida by Sepkoski (2002); to Macominae by Vokes (1980), Squires (1984), Coan et al. (2000), Bouchet et al. (2010); and to Tellinidae by Glenn (1904), Clark and Arnold (1923), Nagao (1928), Nagao (1928), Olsson (1931), Gardner (1943), Durham (1944), Gardner (1947), Moore (1984), Ward and Blackwelder (1987), Lamprell and Whitehead (1992), Frassinetti and Covacevich (1999), Squires (1999), Wienrich (1999), Todd (2001), Moore (2003), Nielson and Valdovinos (2008), Hickman (2015).
