Aequipecten comparilis

Bivalvia - Pectinida - Pectinidae

Taxonomy
Pecten comparilis was named by Tuomey and Holmes (1855) [DISTRIBUTION: Early-Late Pliocene; Atlantic Coastal Plain.]. It is not a trace fossil.

It was recombined as Pecten eboreus comparilis by Dall (1898); it was recombined as Chlamys (Plagioctenium) comparilis by Mansfield (1932), Olsson and Harbison (1953); it was recombined as Pecten (Chlamys) comparilis by Mansfield (1936); it was recombined as Chlamys (Aequipecten) comparilis by Gardner (1943), DuBar (1958); it was recombined as Aequipecten comparilis by Hendy et al. (2008).
