Cirripedia (Crustacea) from the Upper Cretaceous (Campanian) of the Kristianstad Basin and Vomb Trough, southern Sweden

Abstract

The cirripede faunas from the Cretaceous (Campanian) of Skåne, southern Sweden, are reviewed and a total number of 31 species are recorded, the majority of which come from the upper lower Campanian (Belemnellocamax mammillatus Zone) of Ivö Klack, in the Kristianstad Basin. A number of new taxa are described, including the family Angulalepadidae and genus Angulalepas (type species Pollicipes nilssoni Steenstrup, 1839), as are Zeugmatolepas alifera sp. nov., Arcuatoscalpellum carlssoni sp. nov., Regioscalpellum ahlbergi sp. nov., and Epibrachylepas lineatum sp. nov. Pollicipes angelini Darwin, 1851, is placed in the genus Solidoscalpellum Gale, 2025, and Pollicipes undulatus Steenstrup, 1839 in the genus Arcuatoscalpellum Gale, 2015. The palaeoecology of the rocky shoreline cirripede fauna from Ivö Klack is discussed, and taxa are assigned to 6 microniche habitats, determined largely by the degree of turbulence and the nature of the substrates.
