Taxonomic diversity dynamics of early cretaceous brachiopods and gastropods in the Azerbaijanian domains of the Lesser Caucasus (Neo-Tethys Ocean) [PDF]
Palaeontological data available from the Azerbaijanian domains (Somkhit-Agdam, Sevan-Karabakh, and Miskhan-Kafan tectonic zones) of the Lesser Caucasus permit reconstruction of the regional taxonomic diversity dynamics of two groups of Early ...

Latest Albian-earliest Cenomanian monocotyledonous leaves from Australia [PDF]
Two forms of monocotyledon macrofossil are documented from latest Albian-earliest Cenomanian sediments of the Eromanga Basin, central Queensland, Australia. One form is preserved as strap-shaped leaves with cross-linked parallel venation and epidermal features characteristic of monocots.

Albian Stage and Substage boundaries
The base of the Albian Stage has been defined in the European province at the earliest appearance of the ammonite Leymeriella ('Proleymeriella') schrammeni anterior Brinkmann, the earliest member of the important 'mid-Cretaceous' ammonite superfamily Acanthocerataceae. A type section in the Harz foredeep region of northern Germany has been proposed. A

Eocene belemnites from Hungary
Abstract The Middle Eocene nummulitic limestone at Dudar, Transdanubian Hungary, has yielded several belemnite rostra during the last 60–70 years. The correct interpretation of these fossils was made possible by the fact that one of these specimens retained the remnants of the conotheca within the alveolus, while others preserved the conical, tapering ...

Global evolution and paleogeographic distribution of mid-Cretaceous orbitolinids
Members of the Larger Benthic Foraminiferal (LBF) family Orbitolinidae occurred from the Cretaceous to the Paleogene, however, they were most diverse during the mid-Cretaceous, and dominated the agglutinated LBF assemblages described from limestones of ...
