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.

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.

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.

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.

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 ...

ALBIAN LITHOFACIES IN CENTRAL AND EASTERN CISCAUCASUS
International Geology Review, 1964To aid in the search for hydrocarbons a study was made of the lithology and physical properties of Mesozoic sedimentary rocks in central and eastern Ciscaucasus. Of these, the Albian is most interesting because of production in the fields of northern Ciscaucasus. In central and eastern Ciscaucasus, Albian deposits are largely terrigenous.
