Geological range: Eocene to Recent (source: Cox et al., 1969, Treatise N254). The Paleobiology Database recognizes Lunarca as Anadara.
Geographic distribution: A distributional map for modern Lunarca may be accessed from OBIS. A distributional map for ancient Lunarca 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 2 species of extant Lunarca (unvetted). The Paleobiology Database recognizes 5 species from the fossil record (unvetted) (Primary data contributors: Hendy, A. J. W., W. Kiessling, and A. I. Miller.)
Paleoecology: All species of Lunarca are semi-infaunal, actively mobile, unattached or bysally attached suspension feeders. Source: Todd (2015).
