“…From these, a diverse and lowdominance invertebrate fauna has been described (Hammer et al , 2013Wierzbowski et al 2011;Hryniewicz et al 2012Hryniewicz et al , 2014. The non-seep fauna invertebrate diversity was probably also quite high.…”

Abstract:The Late Jurassic Slottsmøya Member Lagerstätte on Spitsbergen offers a unique opportunity to study the relationships between vertebrate fossil preservation, invertebrate occurrences and depositional environment. In this study, 21 plesiosaurian and 17 ichthyosaur specimens are described with respect to articulation, landing mode, preservation, and possible predation and scavenging. The stratigraphic distribution of marine reptiles in the Slottsmøya Member is analysed, and a correlation between high total organic content, low oxygen levels, few benthic invertebrates and optimal reptile preservation is observed. A new model for 3D preservation of vertebrates in highly compacted organic shales is explained.

“…2), there is no sedimentation change which could indicate such condensation; however, changes in sedimentation rate were mentioned by Man (2011). It cannot be excluded that some of the changes in condensation and sedimentation rate might be related to the Mjølnir impact in the Barents Sea, which is thought to have occurred close to the start of the late Berriasian (Zakharov et al 1993;Smelror et al 2001;Dypvik et al 2006;Grabowski 2011;Wierzbowski et al 2011;Wierzbowski & Grabowski 2013). …”

Abstract:In this contribution we examine and discuss recently published magnetostratigraphic data from the Nordvik section (north Siberia) around the Tithonian-Berriasian (J/K) boundary, with a special emphasis on calibration with biostratigraphy and the reliability of both the fossil and magnetic records, as well as sedimentation rates. Specifically, we discuss original new interpretations by Bragin et al. (2013) and the commentary on that work by Guzhikov (2013). We consider some limitations of the Nordvik section, and conclude that the base of M18r, because it is in a condensed part of the sequence, makes a poor contender for precise long-range correlation. We discuss the lack of ammonites at several magnetozone boundaries, and whether the bases of the local zones of Craspedites taimyrensis and Arctoteuthis tehamaensis can be used to bracket the correlative horizon of Calpionella alpina, a widespread marker in the middle of M19n.2n in Tethys.

“…Species-level identification of Amoeboceras found in the current material and thus potentially narrowing down the age of the calcareous sandstone blocks is currently not possible due to lack of individuals with well preserved ventral margin. Zakharov and Rogov, 2008;Wierzbowski et al, 2011). The sandy limestones do not contain any ammonites, therefore, precise dating is problematic.…”

The paper describes Late Jurassic-Early Cretaceous seep carbonate boulders from the Russian Arctic island of Novaya Zemlya, collected in 1875 by A.E. Nordenskiöld during his expedition to Siberia. The carbonates are significantly depleted in heavy carbon isotopes Other seep faunas with similar taxonomic structure are suggestive of rather shallow water settings, but in case of Novaya Zemlya seep faunas such structure might result also from high northern latitude.
