Megaspores and Ostracods from the Rhaeto-Liassic Section in the Boring Rødby No. 1, Southern Denmark
Megaspores and ostracods from the Rhaeto-Liassic section of the boring Rødby No. 1 are studied.
15 species of megas pores are described, of which two are new: Bacutriletes reticuliferus n. sp. and Horstisporires sp. (Type No. 5). Another one, Macrosporites cf. brasserti (Stach & Zerndt) is a derived carboniferous form. Two assemblage zones are defined, namely the T. pinguis Assemblage Zone(below, Rhaetic) and the N. hopliticus Assemblage Zone (above, Lower Lias).
10 species of ostracods from the Lias section are described, of which two are new: Procyrheridea mediorericulata n. sp. and Stenestroemia ? roedbyensis n. sp., and five have open nomenclature. The ostracods from the Rhaetic are registered but not described. The O. aspinata Assemblage Zone (Lower Lias) is defined.
The Rhacto-Liassic section is divided chronostratigraphically in Middle Rhaetic, Upper Rhaetic, Lower Hettangian, Upper Hettangian, and ? Lower Sinemurian.
