Macoma (Psammacoma)

Bivalvia - Cardiida - Tellinidae

Taxonomy
Psammacoma was named by Dall (1900) [Sepkoski's age data: T Mi-l R Sepkoski's reference number: 1112]. It is extant. Its type is Psammotaea candida.

It was reranked as Macoma (Psammacoma) by Gardner (1947), Coan et al. (2000), Moore (2003) and Kafanov and Ogasawara (2003).

It was assigned to Macominae by Woodring (1982) and Perrilliat (1992); to Tellinidae by Todd (2001); to Veneroida by Sepkoski (2002); and to Macoma by Gardner (1947), Coan et al. (2000), Moore (2003) and Kafanov and Ogasawara (2003).
