==FORAMINIFERA FROM THE UPPER CRETACEOUS OF NORTHERN JAMES ROSS ISLAND (ANTARCTICA)==
 +
 +
<font size="2">
 +
During geological mapping of the northern James Ross Island a number of samples from Upper Cretaceous lithologies were gathered to test the presence of foraminifers as a possible tool for stratigraphic evaluation of Upper Cretaceous strata. Limited number of samples did not provide foraminiferal content large  enough to give relevant information for biostratigraphic conclusions. Samples from older sediments of Whisky Bay and Kotick Point formations (Albian  – Turonian) were either not fossiliferous or contained scarce specimens of agglutinated foraminifers. Foraminiferal assemblages from younger sediments of Hidden Lake and Santa Marta formations (Coniacian – Campanian) contained species with both agglutinated and calcareous types of tests. Many of studied marine sediments were barren of foraminifers, probably due to late diagenetic secondary decalcification. Taxonomy of low-diversified assemblages was carried out and a biostratigraphical and palaeobiogeographical significance discussed.

==TAXONOMIC REVISION AND EVOLUTIONARY CLASSIFICATION OF PRAEGLOBOTRUNCANIDS==

[[Image:RevistaEspanola_Cover.jpeg‎‎|left|80px| ]]<font size="2">
 +
The praeglobotruncanid test appearance was iteratively developed in three genera/directional lineages during the late Albian-Santonian. A new genus/directional lineage, ''Bermudeziana'', and a new species, ''Fingeria praeglobotruncaniformis'' are described. A new system of species types is developed for the evolutionary classification, as a tool to describe the morphological changes within a lineage and compare the developments in lineages in which certain features were achieved independently

== WALL ULTRASTRUCTURE AND TAXONOMIC POSITION OF THE GENUS ''Strictocostella'' ==

[[Image:Micropaleontology_front.jpg‎|left|80px| ]]<font size="2">
 +
The details of the shell wall ultrastructure of ''Strictocostella matanzana'' (Palmer and Bermudez) 1936 and ''Strictocostella matanzana'' (Palmer and Bermudez) 1936 ''perytae'' subsp. nov. are investigated for the first time. This study shows that the calcareous shell wall of these two subspecies is monolamellar, consisting of one layer of crystals aligned in a radial direction. This fact necessitates changing the taxonomic position of the genus from the class Rotaliata which is characterized by a bilamellar shell wall to the class Nodosariata whose representatives have a monolamellar shell wall. Some other unique details of the shell and wall structure of the two subspecies studied are also described. The suborder Stilostomellina Saidova 1981 is reinstated and its rank is elevated to that of order.

==''Sanctus sinaicus'',  A NEW AMPHISTEGINID FROM THE UPPER EOCENE OF EGYPT ==
 +
 +
[[Image:Micropaleontology_front.jpg‎|left|80px| ]]<font size="2">
 +
''Sanctus sinaicus'' nov. gen et sp. is described from material collected in the uppermost part of the Khaboba Formation and throughout the Tanka and Tayiba formations of Wadi Thal and Wadi Matulla in West–Central Sinai. We assign this new genus and species to the Late Eocene according to associated planktonic foraminiferal assemblages. Its test is symmetrical in axial section with the division of chambers in the same section similar to that of amphisteginids in their early ontogenetic stage and lacks a canal system. In comparing ''Sanctus sinaicus'' with related amphistegenid species, such as ''Penoperculoides cubaensis'' Cole and Gravell 1952 from the Caribbean; ''Penoperculoides rozlozsniki'' (Méhes) ( ex: ''Nummulites rozlozsniki'' Méhes) from Hungary; and “Non ''Nummulites rozlozsniki''” described by Sander 1962, from the Dammam Formation of Saudi Arabia, we find that ''Sanctus sinaicus'' is similar to ''P. cubaensis'' in the type of coiling and the character of the umbo, which lacks alar prolongations, a canal system and transverse trabeculae, and differs from species of ''Nummulites'' in the central subdivision of chambers.

==CAMPANIAN AGGLUTINATED FORAMINIFERA FROM THE LOMONOSOV RIDGE==
 +
 +
[[Image:Micropaleontology_front.jpg‎|left|80px| ]]<font size="2">
 +
We document the occurrence of agglutinated foraminifera in Upper Cretaceous (Campanian) sediments recovered during the Arctic Coring Expedition (ACEX), IODP Expedition 302. Foraminiferal assemblages consist entirely of agglutinated taxa with 29 taxa including three new species (''Labrospira macilenta'', ''Recurvoidella arctica'', and ''Recurvoides trochoidalis''). The agglutinated assemblage from the Lomonosov Ridge represents a shallow, probably restricted, brackish environment, and displays some taxonomic affinity to Late Cretaceous assemblages described from the Beaufort-Mackenzie Basin. There are no species in common with coeval assemblages described from the southwestern Barents Sea or Western Siberia, and also only several cosmopolitan species in common between the later two regions. Therefore we suggest that the Arctic Ocean was probably isolated from the North Atlantic faunal province during the Late Cretaceous, with very limited or no marine connections between the Arctic, North Atlantic and Western Siberia over the Barents Shelf.

The palaeogeographic setting of the studied Ain Medheker section represents an Early Campanian to Early Maastrichtian moderately deep carbonate shelf to distal ramp position with high rates of hemipelagic carbonate production, periodically triggered by mass-flow processes. Syndepositional extensional tectonic processes are confirmed to the Early Campanian. Planktonic foraminifera identified in thin sections and calcareous nannofossils allow the identication of the following biozones: ''Globotruncanita elevata'', ''Contusotruncana plummerae'' (replacing former ''Globotruncana ventricosa'' Zone), ''Radotruncana calcarata'', ''Globotruncana falsostuarti'', and ''Gansserina gansseri''. The following stable C-isotope events were identified: the Santonian/Campanian boundary Event, the Mid-Campanian Event, and the Late Campanian Event. Together with further four minor isotopic events, they allow for correlation between the western and eastern realms of Tunisia. Frequently occurring turbidites were studied in detail and discussed in comparison with contourites.
