Molluscan Faunas and Biostratigraphy of the Marine Younger Miocene Formations in Denmark. Part II: Palaeontology

Abstract

In this volume there are descriptions of 45 pelecypod species or subspecies, 5 scaphopod species, 107 gastropod species or subspecies, and 3 pteropod species from the marine Younger Miocene formations in Denmark. Most of the species have been pictured on a total of 27 plates.

The following four species have been described as new ones:

Solariella jutensis,
Asthenotoma ravni,
Diaphana moerchi,
Spiratella gramensis.

In Part I of the present work (published in 1966), furthermore, the following three species from the formations investigated were described as new ones: Astarte (Goodallia) esbjergensis, Hinia slieswicia, and Neoguraleus Sæthensis. These three species and Siphonodentalium cf. lobatum (Sowerby) are important species which on account of their importance for the biostratigraphical discussion had to be mentioned in Part I.

Apart from the species which are considered new ones, all the other molluscan species have been described before. However, many species have only been mentioned rather briefly in early palaeontological works. For uniformity's and documentation's sake the species have been described in great detail. Exceptions are some of the species mentioned previously (Rasmussen 1956). Some of the species pictured in the work of 1956 have not been pictured in the present work. In the case of some species, however, there seemed to be reason for offering a new and better picture.
