Abstract:
In order to standardise the taxonomy which accompanies the Upper Cretaceous illustrations in a forthcoming book, 23 new combinations are introduced: Biscutum melaniae, Chiastozygus antiquus, C. trabalis, Lapideacassis asymmetrica, L. bispinosa, L. magnifica, Marthasterites bramlettei, M. crassus, M. simplex, Retecapsa ficula, Staurolithites aachena, S. dentata, S. dorfii, S. elongatus, S. glabra, S. imbricatus, S. integra, S. parma, Tortolithus polygonatus, Zeugrhabdotus biperforatus, Z. burwellensis, Z. ponticulus and Z. spiralis. In addition, a number of taxa were identified which have apparently not yet been formally named. Twenty-four new taxa are described here: Arkhangelskiella antecessor, A. confusus, A. maastrichtiensis, Biscutum thurowii, Chiastozygus stylesii, Cylindralithus? nieliae, Diloma galei, Eiffellithus? hancockii, E. pospichalii, Laguncula montrisouensis. Micrantholithus quasihoschulzii, Micula adumbratus, Neocrepidolithus ruegenensis, Petrarhabdus vietus. Petrobrasiella? bownii, Quadrum bengalensis, Q. svabenickae, Rhagodiscus indistinctus, Semihololithus dens, Staurolithites? aenigma, S. flavus, S. minutes, S. zoensis and Zeugrhabdotus praesigmoides. The search for an SEM illustration of P. vietus led to the discovery of a possible link between Prediscosphaera and Petrarhabdus, and a short note concerning this is also presented here.
