Palliolinae Korobkov 1960
No full textPalliolinae Korobkov in Eberzin, 1960 Diagnosis. Pectinidae with an inner shell surface microstructure of irregularly foliated calcite, producing small reflective surfaces on the inner surface of well-preserved shells. Remarks. This subfamily was defined for the first time by Waller (2006a: 10, fig. 1.2) for genera related to Palliolum and Mesopeplum. Based on morphology and time ranges, he proposed that Palliolum was the stem genus of both Palliolini and Mesopeplini, and evolved from the largely Mesozoic genus Dhontichlamys during late Paleocene time.Published as part of Dijkstra, Henk H. & Beu, Alan G., 2018, Living Scallops of Australia and Adjacent Waters (Mollusca: Bivalvia: Pectinoidea: Propeamussiidae, Cyclochlamydidae and Pectinidae), pp. 113-330 in Records of the Australian Museum (Rec.
