This study presents a sedimentological and stratigraphical description of the Gurlarn site near Passau (SE Germany), which exposes an almost completely preserved Ottnangian near-shore succession of the Upper Marine Molasse in direct contact with the crystalline basement of the Bohemian Massif. Sedimentological features indicate quiet depositional conditions in a depression of the crystalline palaeorelief...
Oncoidal limestones with different oncoid types are ubiquitous in back-reef open-lagoonal and, to a minor amount, in closed-lagoonal facies of the Late Jurassic Plassen Carbonate Platform of the Northern Calcareous Alps. A common feature of the oncoids from moderately to well-agitated open-lagoonal habitats are incorporated small trochospiral benthic foraminifers, tentatively assigned to trochamminids,...
Cold-water coral ecosystems are characterised by a high diversity and population density. Living and dead foraminiferal assemblages from 20 surface sediment samples from Galway and Propeller Mounds were analysed to describe the distribution patterns of benthic foraminifera on coral mounds in relation to different sedimentary facies. Hard substrates were examined to assess the foraminiferal microhabitats...
The Late Oxfordian–Early Kimmeridgian interval of the eastern part of the Paris Basin is characterized by a carbonate succession deposited in shallow-marine platform environments. The Gudmont-Villiers section is represented by deposits ranging from barrier to typical lagoonal environments often poor in macrofossils. Previously unpublished calcareous microfossils are more abundant and provide alternative...
Thaumatoporellacean algae are widespread constituents in Middle Triassic–Cretaceous shallow-marine carbonates of the Tethyan realm. Based on various examples from Mesozoic limestones of Mediterranean platforms (e.g., Dinaric, Apenninic, Apulia) and rare records of Iberia (Pyrenees), Saudi Arabia and Mexico, it is shown that thaumatoporellaceans commonly dwelt as cryptoendoliths in the tests of larger...
Mohlerina basiliensis (Mohler, 1938) represents a common, cosmopolitan, shallow-water Middle Jurassic–Early Cretaceous trochospiral foraminifer. Given the numerous illustrations from thin-section specimens in the literature displaying tests dispersed within the matrix (micritic and sparitic), a free, vagile benthic mode of life is generally suggested. As an exceptional case, specimens are found with...
The poorly known larger benthic foraminifer Balkhania balkhanica Mamontova is reported from the Tirgan Formation (Upper Barremian-Lower Aptian) in the northeastern part of Iran. It was so far only known from Iran (Kopet Dagh and Central Iran), Turkmenistan, and central Afghanistan. Obviously, B. balkhanica possessed a limited distributional area overlapping largely with that of the dasycladalean alga...
Carbonate deposits from Zrin in the Mt. Zrinska Gora were deposited in the SW part of the Central Paratethys Sea during the Middle Badenian (Middle Miocene). The studied section contains a rich fossil community of non-geniculate coralline red algae (Subfamily Melobesioideae), bryozoans, benthic and planktonic foraminifera, echinoderms, ostracods, molluscs, and calcareous nannoplankton. Based on lithological...
A new benthic foraminifer is described as Siphodinarellacostata n. gen., n. sp. from Coniacian shallow-water platform-interior carbonates of Slovenia and Croatia. The new foraminifer is found in skeletal wackestone in association with small benthic foraminifera, thaumatoporellaceans, and calcimicrobes (Decastronema, Girvanella-type tubes). The existence of an internal siphon in Siphodinarella n....
Rich and diverse trocholinid assemblages have been recorded from the lower to middle Cenomanian Altamira and Bielba formations of the Bascocantabrian Basin, northern Spain. They occur in bioclastic for-algal grainstones and near-reefal rudstones referred to platform margin environments. This material, partially impregnated by iron-rich solutions, is unusually well-preserved and offers the unique opportunity...
The lithofacies, microfacies, depositional sequences, and benthic Foraminifera of the uppermost Albian–lower Cenomanian Bielba Formation in its type-area in northern Cantabria, Spain, consisting of a lower siliciclastic member and an upper Cóbreces Member, have been investigated. The investigated section constitutes a hypostratotype for the Bielba Formation, and the lower siliciclastic member is here...
In the shallow-water limestone succession of the Kambühel Formation (upper Maastrichtian to upper Thanetian, Northern Calcareous Alps), the benthic-vagile to encrusting-sessile acervulinid foraminifer Solenomeris Douvillé was identified in upper Maastrichtian and, more commonly, lower Danian rocks. We report on the free nepionic (juvenile) stage of this foraminifer, its relation to the adult encrusting...
