A New Family and Genus of Late Permian Pectinids of the Boreal Superrealm (Pectinida: Voluceropectinidae: Voluceropecten)

The Late Permian pectinid species Aviculopecten volucer Lutkevich et Lobanova (Late Wuchiapingian-Early Changhsingian), previously considered to be a junior synonym of the Middle Permian Vnigripecten phosphaticus (Girty), is reinstated to a valid species. Unusual shell morphology and ornamentation of Aviculopecten volucer make it possible to assign it to a new genus Voluceropecten gen. nov. and a new monospecific family Voluceropectinidae fam. nov. An emended diagnosis of the genus Vnigripecten Muromzeva is presented.
