Anadara Gray, 1847.
Geological range: Late Cretaceous to Recent (source: Cox et al., 1969, Treatise N254). The Paleobiology Database reports the genus extending into the Early Cretaceous.
Geographic distribution: A distributional map for modern Anadara may be accessed from OBIS. A distributional map for ancient Anadara may be accessed from the Paleobiology Database (Primary data contributors: Hendy, A. J. W., W. Kiessling, and A. I. Miller.).
Diversity: The WoRMS database recognizes 90 species of extant Anadara (unvetted). The Paleobiology Database recognizes 269 species from the fossil record (unvetted) (Primary data contributors: Hendy, A. J. W., W. Kiessling, and A. I. Miller.); WoRMS recognizes 1 additional species (30 total).
Paleoecology: All species of Anadara are suspension feeders. Some species are epifaunal, some are semi-infaunal, and some are infaunal (without a siphon). Some species are sedentary (can reposition), while others are actively mobile. Species are either bysally attached ot the substrate, or unattached. Source: Todd (2015).
Phylogenetic status: Paraphyletic. A recent molecular phylogenetic analysis by Combosch and Giribet (2016) does not support the monophyly of Anadara.
