Abstract

A sample ofActinocamax primus Arkhangelsky, 1912 from the Lower Middle Cenomanian limestones of the Wunstorf quarry west of Hannover (NW Germany) is studied by univariate and bivariate biometric methods in order to analyse the variation of critical characters.A. primus is closely related toA. plenus (Blainville, 1825) but differs from that species by being smaller and more slender.A. primus appears in the Lower Cenomanian and continues into the Lower Middle Cenomanian. It is mainly distributed in the northern part of the North European Palaeobiogeographic Province.A. plenus is recorded from the Middle Cenomanian-lower Lower Turonian of the Russian Platform, but only from the Middle Upper Cenomanian in NW Europe. It is widespread in the North European Province.The primus event in the Lower Middle Cenomanian and theplenus event in the Middle Upper Cenomanian are briefly discussed.

Kurzfassung

Eine Aufsammlung vonActinocamax primus Arkhangelsky, 1912 aus Kalken des unteren Mittel-Cenoman des Steinbruches von Wunstorf (westlich von Hannover, NW Deutschland) wird mit univariaten und bivariaten biometrischen Methoden untersucht zur Feststellung der Variation kritischer Merkmale.A. primus ist eng verwandt mitA. plenus (Blainville, 1825), ist aber schlanker und kleiner als diese Art.A. primus tritt erstmalig im Unter-Cenoman auf und läßt sich bis in das untere Mittel-Cenoman verfolgen. Er ist im wesentlichen im nördlichen Teil der nord-europäischen paläobiogeog-raphischen Provinz verbreitet.A. plenus wird vom Mittel-Cenoman bis zum unteren Unter-Turon der Russischen Plattform beschrieben, aber nur aus dem mittleren Ober-Cenoman von NW Europa. Er ist in der nordeuropäischen Provinz weitverbreitet. Der»primus Event« des unteren Mittel-Cenoman und der»plenus Event« des mittleren Ober-Cenoman werden kurz diskutiert.
