«Chlamys (Lyropecten) incertae Tucker-Rowland, 1938, from the upper Eocene or lowermost Oligocene of the northern Florida Peninsula, was placed in Anatipopecten by Nicol et al. (1989), but it differs from the type species in having a weaker hinge dentition and commonly absent secondary radial costae on the disk, with only very faint radial costae or none on its disk flanks. On the basis of these characters, it could equally be regarded as a very early Antillipecten.»
