A Foraminiferal Biostratigraphy of the Lower Senonian
The necessity for a micropalaeontological examination of the lower Senonian chalk of southern England was established during the site investigation of the Thames Barrier, which Is founded on chalk of the Micraster zones. There has been a large amount of detailed stratigraphic and …

Dinoflagellate biostratigraphy of the Cretaceous-Tertiary boundary, Round Bay, Maryland
The Monmouth and Brightseat Formations contain a rich and diverse dinoflagellate assemblage. Thirty-five genera and sixty-six species, of which two genera and eight species are new, are described in this study. The stratigraphic distribution of the taxa is summarized in Figure 4. The content of the …

Foraminiferal biostratigraphy and paleoecology of the Aquia Formation near Hanover, Virginia
Foraminifera of the Paleocene Aquia Formation outcropping near Hanover, Virginia were studied in terms of their taxonomy, stratigraphic distribution and abundance. A total of seventy-nine species were described, eight of which have never been reported in the Aquia. Twenty species of planktonic …

Examining the Molluscan Biostratigraphy of the Upper Cretaceous Judith River Formation, Montana
<p>The "Judith River beds" were discovered by F.V. Hayden in 1855. F.B. Meek helped classified the specimens that Hayden had collected. In the documentations Meek and Hayden, the specimens were collected from the “Judith River Badlands.”' There was no documentation on where in the Judith River …

Conodont biostratigraphy and paleoecology of the Lower Devonian Helderberg Group of Virginia
The occurrences of species of Delotaxis and Icriodus and the Ozarkodina remscheidensis eosteinhornensis--Ozarkodina remscheidensis remscheidensis lineage indicate that (1) most of the Keyser Formation of western Virginia is assignable to the uppermost Silurian eosteinhornensis zone; (2) the top of …

A Foraminiferal Biostratigraphy of the Campanian and Maastrichtian Chalks of the United Kingdom.
The foraminiferal fauna from twenty-seven sections of Campanian and Maastrichtian chalk from both the onshore and offshore United Kingdom have been studied. In total, 160 species and subspecies belonging to 54 genera have been recorded and a complete revision of their systematics, with full …

Foraminiferal biostratigraphy and palaeoecology of the Albian to Santonian (Cretaceous) of Bornholm, Denmark
… for the study interval combining palaeoecology, biostratigraphy, lithostratigraphy and basin events. Transgressive phases are recognised in the Early Albian, Early Cenomanian and Late Cenomanian-Early Turonian. The Coniacian interval overall shows stable outer shelf water depths, whilst the Late …

Miocene herpetofaunas from the central Gulf Coast USA: their paleoecology, biogeography, and biostratigraphy
The late Barstovian Fort Polk herpetofauna represents the most diverse herpetofauna on the Gulf Coast, USA, and includes 15 genera from ten families. The herpetofaunal composition of Fort Polk and Miocene east Texas localities is similar enough to Great Plains localities that they are all …

The biostratigraphy, palaeoecology and geochemistry of a long lacustrine sequence from NW Greece
Examination of an important new 319m core of lake sediment recovered from Ioannina in NW Greece has attempted to relate changes in the lake to variations in the regional climate of south-central Europe over the last 600,000 years. The site is known to have been extremely sensitive to past climatic …

The Palaeo-ecology and Biostratigraphy of the foraminifera from the Oxfordian of north Dorset
The Oxfordian rocks of north Dorset are poorly exposed at outcrop. A drilling operation was devised and implemented and the complete sequence of strata from the Weymouth Member of the Oxford Clay Formation through to the Ringstead Waxy Clay Formation was penetrated. Three boreholes were drilled; …

Macrofossils and biostratigraphy of the Bakken Formation (Devonian and Mississippian) in western North Dakota
<p>The Bakken Formation, up to 145 feet thick in North Dakota, is a subsurface formation in the Williston Basin that typically consists of two black shale members separated by a middle member of predominantly gray siltstone or silty limestone up to 85 feet thick.</p> <p>Well over 500 macrofossils …

Palaeontology and biostratigraphy of the Lower Cretaceous Qihulin Formation in eastern Heilongjiang, northeastern China
The purpose of the study was to provide conclusive evidence for a chronostratigraphical assignment of the Qihulin Formation of the Longzhaogou Group exposed in Mishan and Hulin counties of eastern Heilongjiang, northeastern China. To develop an integrated view of the formation, all collected fossil …

Biostratigraphy and palaeolimnology of late-glacial and holocene lake marls at Quidenham Mere, Norfolk.
In southern Britain there are relatively few natural lakes that have records extending back to the beginning of the Late-glacial. The exceptions are the Meres of central East Anglia that are infilled with organic sediments, providing detailed vegetational records. Of these, Quidenham Mere is unique …
