Sequence Stratigraphy of Campanian-Maastrichtian Strata in Eastern Alabama
… depositional sequence within the Santonian-Campanian aged Blufftown Formation in eastern Alabama. The sequence is approximately late Santonian to early Campanian age and occurs in the sandier basal Blufftown Formation. The late Santonian to early Campanian aged sequence is also marked by …

The magnetostratigraphy of Coniacian-Late Campanian chalk sequences of Southern England
… range in age from Latest Turonian to early Late Campanian and consist of white chalk with flints. Hand samples and large volume rock cores have been collected. Both thermal and AF demagnetisation have been used to remove magnetic overprints. Measurements have been carried out using a CCL …

A Foraminiferal Biostratigraphy of the Campanian and Maastrichtian Chalks of the United Kingdom.
… 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 synonomies …

Campanian-Maestrichtian and Paleocene dinoflagellate and acritarch assemblages from the Maryland-Delaware Coastal Plain
… ranges of species in common, indicates a Late Campanian age; megafossil evidence supports a Late Campanian age, and foraminiferal evidence, a Late Campanian-Early Maestrichtian age for the Mount Laurel (Owens et al., 1970. A correlation of the Monmouth Formation with Wilson's Zone II confirms a …

Provenance, geochronology and sedimentary characteristics of the Campanian M1 Sandstone, Napo Formation, Oriente Basin, Ecuador
The Campanian-Maastrichtian M1 Sandstone is one of the major oil reservoir units of the Napo Formation in the Oriente Basin of Ecuador. Heterogeneous reservoir behavior suggests that the depositional environments of the M1 Sandstone were laterally variable, such that they generated complex …

Evolutionary palaeoecology of the megaherbivorous dinosaurs from the Dinosaur Park Formation (upper Campanian) of Alberta, Canada
… dinosaur assemblage from the upper Campanian Dinosaur Park Formation (DPF) of Alberta, Canada, as a model to test the dietary niche partitioning hypothesis by examining several aspects of ecomorphology known to relate to the procurement and mastication of food. These include feeding …

Stratigraphic Distribution, Taphonomy, and Isotope Paleoecology of the Dinosaurian Fauna in the latest Campanian lower Horseshoe Canyon Formation, Alberta, Canada
… fish supported during the last ~2 m.y. of the Campanian by a coastal lake-strewn wetland occupying what is now south-central Alberta, Canada. Bones accumulated on the floodplain through attritional mortality and are preserved unweathered except for surface polish, scratches, and mottling …

Condensed and Expanded Sections in the Lower Mesaverde Clastic Wedge, Campanian of Wyoming: Evidence for Tectonic Rectification of Sea Level
<p>The stratigraphy of the Cretaceous Western Interior basin indicates that sea level oscillated during the late Cretaceous. The oscillations were polyharmonic, with periods ranging from millions of years to hundred thousands and ten thousands of years. However, there is disagreement over the …

Osteology, Morphometrics, and Phylogenetic Systematics of the ‘Booneville Dinosaur’ (Ornithopoda: Hadrosauridae) From the Early–Middle Campanian Coffee Formation of Northeastern Mississippi
<p>The non-avian dinosaur fossil record of Mississippi includes members of the clades Hadrosauroidea, Nodosauridae, Tyrannosauroidea, Ornithomimidae, Dromaeosauridae, and Ceratopsia. These members are represented only by non-articulated usually isolated elements, deposited in the marine and …

Taphonomic comparison of Hypacrosaurus stebingeri (Hadrosauridae: Lambeosaurinae) bonebeds from the upper Campanian Oldman and Two Medicine formations of Alberta and Montana
Hadrosaurid social structure is still poorly understood. Evidence from bonebeds suggests that juvenile individuals lived apart from herds composed of older individuals, a phenomenon called age segregation. However, the timing at which juvenile individuals became segregated and later rejoined a …

Paleopalynology of the Tar Heel Formation of Atlantic Coastal Plain of North Carolina, United States.
… of taxa) indicates the association of Campanian taxa in the same cluster. This reconfirms that localities of the Tar Heel Formation are of Early Campanian age. Informal biostratigraphic zones of Campanian (CA2-CA4) known from other Atlantic Coastal Plain deposits do not occur in the Tar …

Dinoflagellate cysts of the Gymnodiniaceae, Peridiniaceae, and Gonyaulacaceae from the Upper Cretaceous Monmouth Group, Atlantic Highlands, New Jersey
… and Gonyaulacaceae) are investigated from the Campanian-Maestrichtian Mount Laurel Sand, Navesink Fonnation, and Sandy Hook Member of the Red Bank Sand of Atlantic Highlands, New Jersey. Thirty-seven genera and 91 species belonging to these families were recovered of which 3 genera and 20 …

Paleoenvironmental Reconstruction of the Late Cretaceous Eastern Gulf Coastal Plain in Georgia and Alabama
… 26.8 °C for the Santonian, 23.5°C for the early Campanian, and 28.8°C for the late Campanian. These paleotemperature compare with the modern Gulf Coast mean SST of about 21.8°C. Results of carbon stable isotope analysis for determination of paleosalinity show the method to be useful, but best …
