“…Dispersal of marine Cretaceous faunas often occurred during the transgressive and maximum flooding intervals of sequences (e.g. the belemnite Events in the Cenomanian; Gale and Christensen 1996;Mitchell 2005;Wilmsen et al 2007Wilmsen 2012), but in this case, a late highstand position of both G. mowriensis and M. teigenense can be ascertained as the crippsi Event bundle is capped by the interregional sequence boundary Cenomanian 1 (Robaszynski et al 1998;Wilmsen 2003;Janetschke et al 2015; see discussion above). However, common immigration events during highstands have been proposed by Brett (1998) based on altered water mass properties and open migration pathways following the transgressive reorganisation of the shelf seas.…”

“…9). The thickness of the individual basic cycles varies from 0.2 to 1.3 m. Together, they form a bundle of couplets that gets more calcareous upsection and is terminated by a conspicuous unconformity surface interpreted as oldest intra-Cenomanian sequence boundary (SB Ce 1) capping depositional sequence DS Ce 1 (Gale 1995;Robaszynski et al 1998;Wilmsen 2003;Janetschke et al 2015). This depositional sequence started at a terminal Albian sequence boundary (SB Al 11) and, on the wide NW European epicontinental shelf, subsequent lowstand deposits straddling the Albian-Cenomanian boundary are only developed in deep intra-shelf basins due to the widespread lack of accommodation in up-dip settings (e.g.…”

“…The early Cenomanian was a strongly transgressive time interval characterised by three onlap pulses that led to the retrogradational stacking of three depositional sequences (e.g. Robaszynski et al 1998;Wilmsen 2003;Janetschke et al 2015). The bounding unconformities are sequence boundaries SB Ce 1 to SB Ce 3 ( Fig.…”

The early Cenomanian crippsi Event comprises a 1–3-m-thick interval characterised by mass occurrences of the early Cenomanian inoceramid Gnesioceramus crippsi, identified in the uppermost Sharpeiceras schlueteri Subzone (lower lower Cenomanian Mantelliceras mantelli Zone), below an interregional sequence boundary (SB Ce 1). At Lüneburg, the event is characterised by densely packed, very large, disc-like valves of G. crippsi. Taphonomy as well as bio- and microfacies suggest an event formation in a deeper shelf setting below the storm-wave base as primary biogenic concentration, the inoceramids living as recumbent forms on a soft substrate in dense populations. When tracked between basins, the stratigraphic pattern of the crippsi Event suggests a moderately prolonged phase (< 100 kyr) of increased shell production with rapid deposition aiding in preserving the shell-rich event strata. Towards the basin margins, it grades into storm wave-reworked bioclastic concentrations. The crippsi Event formed by an interregional population bloom and provides, as an proliferation epibole, an important marker for intra- and interbasinal correlation. The first record of G. mowriensis within the crippsi Event at Lüneburg, hitherto endemic to the US Western Interior Seaway, and the occurrence of the ammonite Metengonoceras teigenense, likewise an endemic North American faunal element, from the level of the crippsi Event in northern France indicate faunal exchange between the New and Old worlds during the early Cenomanian. This faunal dispersal and contemporaneous occurrence of warm-water biofacies in Western Europe during the early Cenomanian is explained by the existence of a perpetual NE-directed current transporting warm surface waters from the Gulf of Mexico towards Europe. The occurrence of short-lived M. teigenense in France allows for the calibration of the uppermost schlueteri Subzone of the mantelli Zone in Europe to the lowermost Neogastroplites muelleri Zone in North America and to assign an age of ~ 98.6–98.7 Ma to the crippsi Event.

“…The investigated area is a part of the Lausitz Block, a block-fault mountain and uplift area which dates back to ~92 Ma (Janetschke et al 2015). The main uplift took place between 85 and 50 Ma, what caused denudation of c. 3,000-3,500 m (Lange et al 2008; see also Hofmann et al 2018).…”

The ~30 Ma Stolpen Volcano near Dresden (Saxony) is situated at the western margin of the Lausitz Volcanic Field. It forms a small isolated basaltic hill, the famous Stolpen Castle Hill, penetrating the granodioritic basement of the Lausitz Block and is worldwide the type locality for the term 'basalt', as coined by Agricola (1546). The volcano has always been interpreted as subvolcanic crypto-or lava dome. New geological mapping, dip measurements of the basaltic columnar jointing and the first evidence of scoria for the Stolpen Volcano allow for a new interpretation of the volcanic edifices. On this basis the structure is best described as a maar crater volcano filled by a 110 m thick basanitic lava lake. According to genetic classification, it is a complex monogenetic volcano formed in three phases: (1) a phreatomagmatic diatreme phase with a maar crater, (2) a scoria cone phase with the final basanitic lava lake filling, and (3) a post-volcanic phase with neotectonic uplift, denudation and exposure of a basaltic hill since c. 1.3 Ma. The volcano reconstruction indicates an ongoing change in the eruption style from phreatomagmatic (phase 1) to eruptive and, finally, effusive processes (phase 2) without significant gaps between the eruption episodes. The only difference appears to be caused by a variable water supply during the magma ascent and volcanic eruption. New mineralogical (QAPF) and geochemical (TAS) investigations of the Stolpen lava samples reveal that the Stolpen Hill is not built by a basalt, but basanite trending toward a nephelinite, following the current nomenclature. Microscopic analyses also provide evidence of magma mingling, such as nephelinite melt enclaves, and show local lava contamination by the country-rock granodiorite, also supported by the presence of quartz xenocrysts. The combined field observations, petrography and geochemical data indicate overall heterogeneity of the Stolpen lava. Therefore, the Stolpen Castle Hill is not-in a scientific sense-a suitable type locality for either basalt or basanite. However, the outcropping volcanic rocks as well as their scientific and historical importance undoubtedly give relevance to Stolpen as a type locality for basaltic volcanic rocks in a broader sense.

“…Nominally defined as the Elbtal Group, these sedimentary successions are dominated by marine siliciclastics (nearshore sandstones), marly-silty limestones (Pläner) and hemipelagic marls that reflect both changing energy and water depth across a grain-size graded shelf (T. Voigt, unpub. Ph.D. thesis, Freiberg University of Mining and Technology, 1994; Voigt, 1999; Janetschke & Wilmsen, 2014; Janetschke, Niebuhr & Wilmsen, 2015). The litho-biofacies show marked similarities to coeval sequences in the BCB but, because of their discrete palaeogeographical setting, they are usually treated as a separate basinal system.…”

The Saxonian Cretaceous Basin constitutes an important source of rare Late Cretaceous marine amniote fossils from Germany. It is also historically famous, having been documented in a series of monographic works published by the distinguished German palaeontologist Hanns Bruno Geinitz in the nineteenth century. The most productive rock units include the upper Cenomanian Dölzschen Formation and upper Turonian Strehlen and Weinböhla limestones (lower Strehlen Formation). A survey of curated specimens recovered from these deposits has now identified isolated teeth of probable polycotylid and elasmosaurid plesiosaurians, as well as several humeri that are referred to protostegid marine turtles. The Saxonian Cretaceous Basin formed a continuous epeiric seaway with the Bohemian Cretaceous Basin during late Cenomanian – Turonian time. A western connection to the North Sea Basin also existed via the North German and Münsterland Cretaceous basins. The Mesozoic marine amniote remains from these regions therefore record a coeval northern European fauna that was probably homogeneous across the northern peri-Tethyan margin during Late Cretaceous time.
