Albian pelagic rhythms (Piobbico Core)
Journal of Sedimentary Research, 1991Abstract The Piobbico core of Aptian-Albian pelagic rhythmites in Italy has been used to explore ways of extracting quantitative time-series of geological, chemical, physical and biological parameters from stratigraphic sequences. Recognition of the precession, obliquity, and eccentricity cycles (the Option frequencies) has permitted ...

ON THE PHYLOGENY OF THE LATE ALBIAN GENUS PLANOMALINA
The Journal of Foraminiferal Research, 2006The ancestor-descendant relationships of the late Albian Planomalina lineage have been reconstructed using morphologic observations obtained from the Scanning Electron Microscope and supported by morphometric analysis using X-ray images of the shell ontogeny.

The Stratigraphy of the Albian Beds at Leighton Buzzard
Geological Magazine, 1947The unusually interesting Albian beds exposed in the neighbourhood of Leighton Buzzard in Bedfordshire have been the subject of descriptive papers by Lamplugh and Walker (1903), Kitchin and Pringle (1920), and Lamplugh (1922), as well as a number of short notes and excursion reports.

Paleoceanography of the northwestern Pacific during the Albian
Palaeogeography, Palaeoclimatology, Palaeoecology, 2007Abstract The deep ocean conditions and circulation during the Cretaceous have been characterized mainly by the sediments from the Tethys Sea and the proto-Atlantic Ocean, because sedimentological data from the Pacific basin from that period have been quite limited. Here we present new geochemical measurements from sediments that we collected from two

Albian Foraminifera of the Rumanian Plain
Micropaleontology, 1965Describes foraminifera (including one new species and new subspecies) from marly Albian (Cretaceous) deposits of the Giurgiu and Putineiu regions. Tabulated data on biozonal distribution of the fauna are included.

Evolution of radiolarians in the late Albian–Campanian
Stratigraphy and Geological Correlation, 2016The dynamics of radiolarian evolution in the late Albian–Campanian is analyzed, and several stages are recognized. The first stage (late Albian–middle Cenomanian), related to the MCE regional anoxic event, showed low evolutionary tempos and hence lacked structural change in radiolarian communities.

Albian Foraminifera of the Yukon Territory
1978The results of this study provide a foraminiferal reference sequence for the Albian Stage in the Yukon Territory, a previously little-known region between the Alaskan North Slope and the Canadian Western Interior. Eighteen families, forty-three genera, and one hundred and thirty-five species of the order Foraminifera are reported from the Albian ...

Cladistic analysis of Albian heteromorph ammonites
Palaeontology, 1999A computer‐based parsimony analysis of Albian heteromorph ammonites from the Tethyan and European faunal provinces is demonstrated. The results indicate that whilst Anisoceratidae, Baculitidae, Scaphitidae and Turrilitidae are monophyletic, Hamitidae is not.

Micropaleontology of Albian to Danian Strata in Madagascar
Micropaleontology, 1982Ten surface samples of Albian to Danian strata from Madagascar have been examined for planktonic foraminifera, calcareous nannoplankton and palynomorphs including dinoflagellates. The stratigraphical results based on these micropaleontologic groups have been compared with data based on megafossils, mainly ammonites.

Radiolarian paleobiogeography in the late Albian–Santonian
Stratigraphy and Geological Correlation, 2016Radiolarian paleobiogeography for the late Albian–Santonian is proposed for the first time. The paleobiogeographic differentiation is found to be different for the Albian, Cenomanian, Turonian, and Coniacian–Santonian. The Tethyan and Boreal superrealms can be recognized for the Albian–Santonian.
