Argopecten (calico scallop)

Bivalvia - Pectinida - Pectinidae

Taxonomy
Argopecten was named by Monterosato (1889) [Sepkoski's age data: T Mi-l-l R]. It is extant.

It was reranked as Chlamys (Argopecten) by Tavora et al. (2004).

It was assigned to Aequipectini by Coan et al. (2000); to Pectinidae by Moore (1984), Ward and Blackwelder (1987), Todd (2001); to Pterioida by Sepkoski (2002); to Chlamys by Tavora et al. (2004); and to Chlamydinae by Woodring (1982), del Rio (1992), Morales-Ortega et al. (2016).
