ABSTRACT Schneider, S., Jager, M., Kroh, A., Mitterer, A., Niebuhr, B., Vodražka, R., Wilmsen, M., Wood, C.J. and Zagoršek, K. 2013. Silicified sea life - Macrofauna and palaeoecology of the Neuburg Kieselerde Member (Cenomanian to Lower Turonian Wellheim Formation, Bavaria, southern Germany). Acta Geologica Polonica, 63(4), 555-610. Warszawa. With approximately 100 species, the invertebrate macrofauna of the Neuburg Kieselerde Member of the Wellheim Formation (Bavaria, southern Germany) is probably the most diverse fossil assemblage of the Danubian Cretaceous Group. Occurring as erosional relicts in post-depositional karst depressions, both the Cretaceous sediments and fossils have been silicified during diagenesis. The Neuburg Kieselerde Member, safely dated as Early Cenomanian to Early Turonian based on inoceramid bivalve biostratigraphy and sequence stratigraphy, preserves a predominantly soft-bottom community, which, however, is biased due to near-complete early diagenetic loss of aragonitic shells. The community is dominated by epifaunal and semi-infaunal bivalves as well as sponges that settled on various (bio-) clasts, and may widely be split into an early bivalve-echinoid assemblage and a succeeding sponge-brachiopod assemblage. In addition to these groups we document ichnofauna, polychaete tubes, nautilids and bryozoans. The fauna provides evidence of a shallow to moderately deep, calm, fully marine environment, which is interpreted as a largescale embayment herein. The fauna of the Neuburg Kieselerde Member is regarded as an important archive of lower Upper Cretaceous sea-life in the surroundings of the Mid-European Island.

Stage Boundaries

Four large quarries in northern Germany provide a continuous section from the Middle Coniacian to Upper Maastrichtian, consisting almost throughout of a white chalk facies. The combined section has a thickness of 570 m. It has been sub-divided biostratigraphically into 33 zones. The vertical ranges of the species of the stratigraphically relevant groups have been determined on the basis of about 30 years of systematic collecting of fossils bed by bed. Belemnites, inoceramids, echinoids, crinoids and brachiopods occur throughout the section, ammonites only in the Campanian and Maastrichtian. The following proposals are put forward for the definition of the stage boundaries: Campanian/Maastrichtian: appearance of Belemnella lanceolata, nearly coincident with the first occur­rence of Hoploscaphites constrictus; Santonian/Campanian: level of phylogenetic development of Gonioteuthis granulataquadrata from G. granulata, coincident with the extinction of Marsupites testudinarius; Coniacian/Santonian: appearance of Inoceramus ( Cladoceramus) undulatoplicatus nearly coincident with the appearance of the Inoceramus pachti!cardissoides group.
