The redescovery and exact location of Biplanisipira and abundant, free Pellatispira on the slopes of Puig Aguilera in the Igualada basin triggers the disscusion about the age of the first apperance of so many other genera considered so far as restricted to the Priabonian. In the Igualada basin, Biplanispira, Pellatisipira, Heterostegina reticulate and Silvestriella are found together with the other, larger foraminifera considered older than Priabonian. i.e. with Nummulites ptukhiani, Assilina schwageri and A. roselli . These latter species belong to lineages known to evolve constinuously from Lutetian to Pirabonian. The three representatives of the phyia concurrently indicate a Bartonian age of sediments yielding Pellatispira and its associates.

Pseudorhapydionina laurinensis, P. dubia, P. anglonensis and Pseudorhipidionina casertana (Subfamily Pseudorhapydionininae) from the Iberian Range are restudied. The age of the deposits containing these species is late Cenomanian. However, a small Pseudorhapydionina (named in this work as P. aff. laurinensis) occurs in the lower Cenomanian deposits suggesting that the origin of the group is in the earliest Cenomanian

An integrated stratigraphic, palaeontological, palaeoenvironmental and palaeogeographical study of the traditionally considered Upper Jurassic–Lower Cretaceous dinosaur-bearing sedimentary record (DSR) of eastern Spain is accomplished for the first time. Several areas where dinosaur fossils are abundant (western Maestrazgo and South-Iberian basins) have been studied in detail. In all the areas, the DSR comprises a carbonate-dominated lower part (CLP), and an essentially siliciclastic upper part (SUP). Deposition occurred in a shallow-very shallow marine carbonate platform, laterally connected towards the N and W to coastal and alluvial environments. The overall upwards evolution is regressive with a transgresive episode at the uppermost part. The DSR includes deposits previously assigned, depending on the studied area, from the Kimmeridgian to the Barremian (locally even to the Aptian–Albian). However, ages obtained in this work from larger benthic foraminifera (LBF), demonstrate a Kimmeridgian–Tithonian age (locally Kimmeridgian-Early Berriasian?) for the DSR. These findings have important implications regarding the age of dinosaur fossils of these deposits, traditionally assigned to the Jurassic-Cretaceous transition, or even to the Early Cretaceous, erroneously, and have necessitated a deep litho- and chronostratigraphic revision of the units previously established in the studied areas: new data indicate that the DSR is correlatable with deposits of the Villar del Arzobispo Fm and that the usage of the Aldea de Cortés and El Collado Fms, traditionally assigned to the Early Cretaceous, should be avoided. New data also reveal that the DSR should be correlated with other Kimmeridgian–Tithonian dinosaur-bearing deposits of Iberia, such as those of the Cameros Basin, Asturias and Portugal, and have encouraged a revision of the Iberian palaeogeography at that time. In fact, ages obtained from LBF agree with data provided by the systematics of dinosaurs, since dinosaur faunas of eastern Spain are similar to those of the other Late Jurassic Iberian areas, especially to those of the Lusitanian Basin.

A new porcelaneous larger benthic foraminifer, Reticulotaberina jahrumiana new genus and new species, from the latest middle Eocene shallow-water carbonate platform deposits of SW Iran (Jahrum Formation, Zagros Mountains) is described. Its structure is characterized by the development of a thin alveolar layer (exoskeleton) in the marginal area of the chamber lumen and by septula and interseptal pillars (endoskeleton) in the central area. The septula build a network, whereas the interseptal pillars rise from its intersections. The intercameral foramina are concentrically arranged and are intercalated with septula. R. jahrumiana n. sp. displays a strong dimorphism: A-form has a planispiral-uncoiling subcylindrical morphology, whereas the B-form presents a flared shape with oval or compressed outline. The new taxon is included in the Praerhapydioninidae family and is so far known from the south-west of Iran. The age is late Bartonian. (C) 2019 Elsevier Masson SAS. All rights reserved.

The Upper Cretaceous Terradets Limestone of the south Pyrenean Basin consists of two subunits, named the Lower Terradets and the Upper Terradets. In the Lower Terradets subunit, sedimentological features and fossil content permit distinguishing mid-ramp, bioclastic shoal and inner-ramp lagoonal facies associations, each characterized by a distinctive larger foraminiferal assemblage. Mid-ramp facies contain epibenthic, relatively small foraminifera like Cuneolina cylindrica, Dictyopsella cf. cuvillieri, Pseudocyclammina sphaeroidea, Nummofallotia cretacea, Fallotia ? sp., Pararotalia cf. tuberculifera, Praestorrsella roestae and Praesiderolites praevidali. Bioclastic shoal facies are dominated by Orbitoides cf. tissoti, Praesiderolites douvillei and Pseudosiderolites sp. The inner-ramp lagoonal facies contain a rich and diverse assemblage of epiphytes, like Ilerdorbis decussatus, Dicyclina schlumbergeri and Cyclopsinella roselli n. sp., and epibenthic foraminifera, like Calveziconus lecalvezae and Orbitokathina campaniana. Strontium isotope stratigraphy indicates a middle Campanian age for the Lower Terradets limestone.

Siderolitid larger benthic foraminifera are widespread and abundant microfossils in high-energy shallow-water Tethyan carbonate platform facies of Campanian - Maastrichtian age. The more evolved representatives of this group, placed in the genus Siderolites, are characterized by a complex canal system and by canaliculate spines. For these characters they have been often compared to recent calcarinids. The specific name Siderolites calcitrapoides has been almost invariantly used for all Maastrichtian siderolitids with spines. In this paper we give the first accurate description of the siderolitids occurring in the Maastrichtian carbonate platform facies of the Salento Peninsula (southeastern Apulia) and of the Pachino area (southeastern Sicily). The architecture of the test of these siderolitids differs considerably from that of true S. calcitrapoides. For these morphotypes we erect the new taxon Canalispina iapygia gen. et sp. nov. The new taxon developed longer and more robust spines by changing the architecture of the canal system and by embodying the base of the spines within the chambers. Biostratigraphy and strontium isotope stratigraphy support a late Maastrichtian age for the studied material, indicating that Canalispina iapygia gen. et sp. nov., represents the last step in the evolution of siderolitids before the extinction of the group at the Cretaceous-Paleocene boundary.

The western margin of the Caribbean Plate is a typical example where oceanic and continental terranes have amalgamated by subduction, collision, and strike‐slip processes. The boundaries between these blocks, as well as their tectonostratigraphic records, are generally covered by younger deposits and dense tropical vegetation, which may hamper reconstructing the accretionary evolution of the convergent margin. In that context, the study of overlap sedimentary assemblages represents an important tool to constrain the accretion timing of terranes. In northern Central America, the geology of the suture zone between the Chortis Block and the exotic Siuna Intraoceanic Arc indicates that the two terranes were assembled together during a Hauterivian arc‐continent collision (approximately 134–131 Ma). The exotic origin of the intraoceanic arc is based on the nature of metamorphic blocks within and the kinematics of the Siuna Serpentinite Mélange. The short duration of the collision event is suggested by coeval exhumation of the Siuna Serpentinite Mélange and Chortis‐derived coarse sedimentation (El Amparo Formation) along the suture zone, rapidly followed by onset of pelagic sedimentation (Rio Matis Formation). Although the collision appears to have been short lived and preserved only in the suture zone, postcollisional extension affected intra‐arc to back‐arc settings of the Chortis Block and led to the formation of kilometer‐thick extensional basins. We envisage that the convergent margin inboard of SW Mexico—represented by the fringing Guerrero Intraoceanic Arc and the Mixteca continental terrane—underwent similar postcollisional extension, whereas the western margin of the proto‐Caribbean oceanic realm experienced onset of WSW dipping subduction beneath the accreted Siuna Intraoceanic Arc.

We studied the architecture and biostratigraphical distribution of the imperforate larger benthic foraminifera from the upper part of the Jarhum Formation in the Fars Interior (Zagros, Iran) and identified 15 taxa belonging to the families Coskinolinidae, Orbitolinidae, Austrillinidae, Praerhapydioninidae and Soritidae. This foraminiferal assemblage indicates deposition in warm, shallow (upper photic zone), relatively oligotrophic conditions compatible with an inner-ramp setting. The age attributed to the assemblage is Bartonian-earliest Priabonian.

The siderolitids from the uppermost Campanian and Maastrichtian deposits of the Pyrenees have been re-studied. This has revealed a high diversity and rapid replacement of taxa, confirming the group as a good tool for high resolution biostratigraphy. Two genera have been found in the uppermost Campanian-Maastrichtian interval in the Pyrenean deposits: Siderolites Lamarck, and Wannierina Robles-Salcedo. Siderolites, with canaliferous spines or denticulate periphery, is represented by four species replacing each other from the latest Campanian to Maastrichtian: Siderolites praecalcitrapoides (latest Campanian), S. pyrenaicus sp. nov. (early Maastrichtian), Siderolites calcitrapoides (late Maastrichtian) and Siderolites denticulatus (late Maastrichtian). Wannierina is characterised by well developed keels and ramified marginal canals. Two species of Wannierina have been identified and they succeeded one another from latest Campanian to early Maastrichtian: Wannierina vilavellensis sp. nov. (latest Campanian) and Wannierina cataluniensis (early Maastrichtian). The species of the genus Siderolites inhabited shallow waters of tropical to subtropical platforms with moderate-to-high water energy conditions and those of the genus Wannierina are typical of deep water low-energy environments but still in the eutrophic zone.

A detailed sedimentological and paleontological study of the Late Santonian-Late Campanian carbonate platform deposits of the Serres Marginals area (South margin of the Pyrenean Basin) has been performed. Three depositional shallow carbonate sequences have been distinguished (CI, C2 and C3). Within the shallow platform sequences moderate energy subtidal to intertidal, high energy sand-shoal, protected lagoon and restricted lagoon to lacustrine fades have been identified.

The study of the microfauna of the lower member of the Cárdenas Formation occurring in the Cárdenas Basin (San Luis Potosí, NE México) has been carried out at the type-locality of Lepidorb itoides minima Dovillé. A re-examination of the larger foraminifera sampled in this locality, in addition to the study of the associated planktonic foraminifera and ostracodes, suggest a deposition in an open marine environment with terrigenous input during the middle-upper Campanian (Globotruncana ventricosa Zone and/or calcarata Zones). These preliminary results might be useful to precise the geological setting of the Cárdenas Formation. Moreover, the comparison of the studied microfauna with other Upper Cretaceous Tethyan ones have led to establish its strong similarities with the microfauna found in the Caribbean realm and the U.S. Gulf Coastal Plain but its tenuous European affinities.

A new conical agglutinated foraminifer, Lepinoconus chiocchinii gen n., n. sp. from the lower Campanian shallow-water platform deposits of the Lepini Mountains (central Apennines, Italy), is described. It has a pseudo-keriothecal wall structure, uniserial arrangement of the adult chambers and multiple apertures. The exoskeleton is constituted by beams (main and intercalary) continuous from one chamber to the next, while the endoskeleton bears pillars. The new taxon is included in the Coskinolinidae family. Lepinoconus chiocchinii gen. n., n. sp. is known from southern Italy, Greece and Albania.

The Soritoidea (Foraminifera) represent an important component of Cenomanian microfossil assemblages of the central and southern Tethyan carbonate platforms and are widely used as biostratigraphic markers. In this paper a new taxon, Fissumella motolae n. gen. n. sp., is described from the Cretaceous carbonate platform facies of central and southern Italy. It is characterized by its small size, planispiral-involute arrangement of chambers, fissure-shaped single aperture and few and short radial septula subdividing the marginal lumen of the chambers. Fissumella motolae n. gen. n. sp. represents the first soritoidean in the fossil record showing internal subdivisions of the chamber lumen. Carbon isotope stratigraphy supports an earliest Albian age for this significant step in the evolution of the superfamily Soritoidea. The new subfamily Fissumellinae is established for soritoidean foraminifera with planispiral-involute lens-shaped shells, single aperture and chamber lumen subdivided by few and short septula.
