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.

The Albian-Cenomanian boundary in northern California
Geological Society of America Bulletin, 1996There is no internationally agreed-upon stratotype for the Albian-Cenomanian (Lower Cretaceous–Upper Cretaceous) boundary. Type sections in France for the Albian and Cenomanian Stages are inadequate for this purpose. The proposed boundary stratotype sections in North Africa and Texas that were discussed in Copenhagen at the 1983 Third International ...

An ocean‐facing Aptian–Albian carbonate margin, Oman
Sedimentology, 2001A high‐energy Aptian–Albian platform margin in northern Oman fronted onto an open oceanic basin, making the area a valuable analogue for coeval guyot margins. Most similar aged carbonate margins described in the literature faced either intracratonic or minor oceanic basins.
