Community persistence and the pattern of community variability over time: a test using fossil assemblages from four marine transgressions in the Breathitt Formation (Middle Pennsylvanian) of Eastern Kentucky
Four intervals of Middle Pennsylvanian marine strata in the Breathitt Formation of eastern Kentucky, the Elkins Fork, Kendrick, Magoffin, and Stoney Fork, were measured, sampled for fossils, and described. Each marine interval was shown to be the product of a single episode of transgression and …

Magnetic records from latest Triassic to earliest Jurassic red beds, Utah and Arizona, and from mid-Pleistocene lake beds, New Mexico
… from the Upper Triassic to Lower Jurassic strata of the Moenave Formation, southern Utah and northern Arizona, were used to construct a composite magnetostratigraphy and further refine the position of the base of the Jurassic in the southwest U.S.A. The composite magnetostratigraphy …

Variations in the architecture of fluvial deposits within a marginal marine setting, Eocene Sobrarbe and Escanilla formations, Spain
Fluvial systems located near marginal-marine settings are prolific hydrocarbon reservoirs around the world. Outcrops that contain strata that can be correlated from fluvial deposits to coevally deposited marginal marine deposits are important because they provide a rare opportunity to relate …

Deep-marine depositional systems of the western North Atlantic: Insights into climate and passive-margin evolution
… given depositional environment, deposits in deep-marine settings, particularly passive margins, provide a unique, long-term record of paleoclimate, paleoceanography, and tectonics affecting the basin in question. Whereas deep-marine strata may be used to answer myriad of questions regarding the …

Impacts of Geological Variability on Carbon Storage Potential
… regimes at the seafloor, we locate and quantify marine strata that has "self-sealing" properties, a storage option that we find is plentiful off the coasts of the United States. We conclude that further research into transport optimization that takes into account the true variation in geological …

Understanding the theatre of terrestrialization: Silurian-Devonian sedimentary landscapes and continental ecosystems
The colonization of subaerial and non-marine landscapes (“terrestrialization”) by animals and plants was a defining and irreversible innovation during the co-evolution of Earth and its biosphere. Its timing, estimated through ichnological evidence, suggests Cambro-Ordovician excursions were …
