ABSTRACT The middle part of the Fairpoint Member Fox Hills Formation in Meade County, South Dakota consists marine shoreface deposits and contains a chondrichthyan assemblage that includes both pelagic bottom-feeding forms. genera (e.g., Rhombodus, Carcharias, Serratolamna, Ischyrhiza) widely known from Upper Cretaceous rocks Western Interior, other parts North America, Europe, Africa, Asia. This many same reported by Cicimurri (1998) lignitic Stoneville lithofacies upper Member....
The Crystal Geyser Dinosaur Quarry contains a large monospecific accumulation of bones from basal therizinosaur, Falcarius utahensis.The quarry is located approximately 16 km south Green River, Utah, at the base early Cretaceous (Barremian) Yellow Cat Member Cedar Mountain Formation.Fossil in occur three units that have distinct taphonomic, lithologic, and geochemical characteristics.Rare earth element compositions fossils suggest each unit were drawn different reservoirs or sources having...
Abstract The Main Fossiliferous Layer (MFL) is a concentration of vertebrate and invertebrate fossils, 20 to 30 cm thick, preserved in sequence glauconitic sand at or near the Cretaceous–Paleogene boundary New Jersey (USA) coastal plain. Several hypotheses have been proposed explain origin age MFL, including: marine transgression formation lag deposits reworked bones shells, condensed section attritional accumulation fossil material, catastrophic collapse Late Cretaceous ecosystems following...
The Foreknobs Formation (Upper Devonian; Upper Frasnian to basal Famennian) comprises the uppermost marine strata of progradational "Catskill clastic wedge" south-central Appalachian Mountains (Virginia-West Virginia; USA). consists 14 lithofacies arranged in four facies associations which record following depositional settings: 1) storm-dominated distal proximal offshore shoreface (facies association A); 2) sharp-based conglomeratic B); 3) fluvial redbed C); and 4) incised-valley fill (IVF;...
Degree of bioturbation, Thalassinoides isp. morphology, and diameters were compared across the Cretaceous–Paleogene (K–Pg) boundary interval at three localities along New Jersey coastal plain. Within this regionally extensive ichnoassemblage, mean burrow decrease abruptly by 26–29% (n = 1767) base Main Fossiliferous Layer (MFL) or laterally equivalent horizons. The MFL has been previously interpreted as K–Pg based on last occurrence Cretaceous marine reptiles, birds, ammonites, well iridium...
River floodplains can be both sources and sinks for organic carbon. In the sedimentary record, geochemical signatures of terrestrial water availability record climate ecology along river corridors in deep time. However, paleoenvironmental reconstructions are often confounded by complex dynamics carbon residence, entrainment, deposition a fluvial system. As alluvial rivers migrate across their basins, they erode older deposits, integrating environmental with that other sediment transport....

Abstract An accurate and precise geomagnetic polarity time scale is crucial to the development of a chronologic framework in which test paleoclimatic paleoenvironmental interpretations marine terrestrial records Eocene–Oligocene transition (EOT). The magnetic patterns relatively continuous EOT have been dated using both radio-isotopic techniques astronomical tuning, can achieve precision approaching ±30 k.y. for much Paleogene. However, age reversals between chrons C12n C16n.2n has proved...
The supposition that the Late Devonian Gondwanan glaciation should be recorded in more temperate regions by black shales, incised valleys, and lowstand wedges is tested with reference to Foreknobs Formation (late Frasnian early Famennian) of central Appalachian Basin (USA). upper (early portion a proximal strike belt eastern West Virginia contains an erosionally based, coarse, conglomeratic, valley fill (IVF) underlain overlain strata deposited relatively deep-marine, ramp setting. A signal...
Abstract Studying the centennial or millennial timescale response of large rivers to changing patterns in precipitation, discharge, flood intensity and recurrence, associated sediment erosion is critical for understanding long‐term fluvial geomorphic adjustment climate. Long hydrographs, maintaining reliable Flow Duration Curves (FDCs), are a fundamental input such simulations; however, recorded discharge series rarely span more than few decades. The absence robust methodologies generating...
In 1993–1994, researchers at Oak Ridge National Laboratory collected high‐resolution airborne geophysical data on the Reservation, Ridge, TN. The were in part to address concerns about possible undocumented hazardous waste sites. Interpretation of aeromagnetic was complicated, however, by discovery remote areas numerous small magnetic anomalies natural origin. Magnetic susceptibility measurements core showed that underlying Copper Dolomite non‐magnetic. We attribute presence ferromagnetic...
