Brachiopod events in the European Middle Cretaceous (Aptian-Cenomanian)
Cretaceous Research, 1981Abstract Brachiopod events in the European Middle Cretaceous (Aptian-Cenomanian). Brachiopod species proliferated in the Late Aptian and Cenomanian. Significant palaeobiogeographical events took place during the Middle Cretaceous, in particular during Early and Late Albian time.

Ammonites of a new genus, Kislovodskoceras gen. nov., with the type species K. kislovodskense sp. nov. (fam. Desmoceratidae), are described from the Middle Aptian of the vicinity of Kislovodsk. The shell shape and sutural ontogeny are discussed. Findings of the new taxon are confined to the middle part of the Epicheloniceras subnodosocostatum Zone, for

New Data on Stratigraphy and Distributions of Glendonites from the Carolinefjellet Formation (Middle Aptian–Lower Albian, Cretaceous), Western Spitsbergen [PDF]
Stratigraphy and Geological Correlation, 2021 Abstract The Aptian deposits on Spitsbergen Island are poorly studied. Moreover, there were no published data on fossil distribution in the Aptian and Albian in the vicinity of the town of Longyearbyen. This article provides new data on ammonite-based biostratigraphy of the Carolinefjellet

Middle Aptian biostratigraphy and ammonoids of the Northern Caucasus and Transcaspia
Paleontological Journal, 2016The Middle Aptian deposits of the central and eastern regions of the Northern Caucasus and Transcaspia (Turkmenistan) are described and discussed, including the history of their studies, lithology, and characterization of ammonite zones in each region. Ammonites of the superfamilies Parahoplitoidea and Douvilleiceratoidea, which form the basis for the ...

Abstract Significant influence of anoxic events on faunal turnovers in marine communities is well-established. However, many studies are focused on the impact of anoxic conditions on benthic organisms, while coeval changes in pelagic cephalopod assemblages remain relatively poorly understood.

Possible Insect Eggs in Palynological Preparations from the Aptian (Middle Cretaceous) of Brazil
Micropaleontology, 1986A group of microfossils is described from Middle Cretaceous (Aptian) sediments of Brazil considered to have formed in a brackish-water, possibly deltaic environment. The microfossils have the form of oblate spheroids with reticulate surfaces interrupted by two bands of elongate fields and with a distinct, circular operculum; the name Mystheria ...

Cretaceous Research, 2016 Abstract The angiosperm pollen record from the Anfiteatro de Tico and Punta del Barco formations (Baquero Group) is reported. The relevance of these floras is that they are accurately dated as late Aptian, and one of the oldest floras southern South America with fossil angiosperms.

Abstract Cauvery Basin, a pericratonic rift basin along the Eastern Continental Margin of India, evolved during the breakup of the Eastern Gondwanaland. It exposes both syn-rift and later post-rift passive margin deposits ranging from Barremian to Miocene.

A detailed cyclostratigraphic study conducted on several proxies including spectral gamma ray, magnetic susceptibility, clay minerals, and carbonate content suggests that the return to equilibrium in the carbon cycle after the major disturbance linked with Oceanic Anoxic Event 1a occurred in about 2 Myr. The minimum duration of the D.
