Jurassic Scaphopoda from the Russian platform: Pulsellidae and Gadilidae

Abstract

The scaphopod families Pulsellidae and Gadilidae from sandy and clayey beds of the Jurassic (Callovian‒Volgian) of European Russia are investigated. In Pulsellidae, the following taxa are described: Annulipulsellum with two subgenera, Annulipulsellum (species A. ambiguum sp. nov., A. rugosum sp. nov.) and Mesopulsellum subgen. nov. (A. alternoides sp. nov., A. calloviense sp. nov., A. hirtistriatum sp. nov., A. medium sp. nov.), Gracilipulsellum gen. nov. (G. iodaense sp. nov.), Gardneridentalium gen. nov. (G. primitivum sp. nov., G. reticulatum sp. nov.), and Mesoentalina gen. nov. (M. fabulosa sp. nov.). New taxa of the family Gadilidae include the genus Mesoantalis gen. nov. with the species M. clava sp. nov., M. expolitum sp. nov., and M. volgense sp. nov.
