Chemostratigraphic implications of spatial variation in the Paleocene‐Eocene Thermal Maximum carbon isotope excursion, SE Bighorn Basin, Wyoming

Autor: Allison A. Baczynski, Francesca A. McInerney, Scott L. Wing, Mary J. Kraus, Jonathan I. Bloch, Doug M. Boyer, Ross Secord, Paul E. Morse, Henry C. Fricke

The Paleocene‐Eocene Thermal Maximum (PETM) is marked by a prominent negative carbon isotope excursion (CIE) of 3–5‰ that has a characteristic rapid onset, stable body, and recovery to near pre‐CIE isotopic composition. Although the CIE is th

Testing hypotheses on signatures of precipitation variability in the river and floodplain deposits of the Paleogene San Juan Basin, New Mexico, U.S.A

Autor: Piret Plink-Björklund, Kristine L. Zellman, Henry C. Fricke

Publikováno v: Journal of Sedimentary Research. 90:1770-1801

Much progress has been made in recent years towards a set of recognition criteria for river discharge variability in river channel deposits, and thus sedimentary proxies for precipitation variability. Despite this progress, there is currently no cons

Paleoenvironments, taphonomy, and stable isotopic content of the terrestrial, fossil-vertebrate–bearing sequence of the El Disecado Member, El Gallo Formation, Upper Cretaceous, Baja California, México

Autor: Kaori Tsukui, Paul Hall, René Hernández-Rivera, David E. Fastovsky, Henry C. Fricke, Gregory P. Wilson, Geraldo Alvarez, Jahandar Ramezani, Marisol Montellano-Ballesteros

Publikováno v: Geosphere. 16:991-1011

The Late Campanian (Late Cretaceous), upper part of the El Disecado Member, El Gallo Formation, Baja California, México, preserves a rich fossil assemblage of microvertebrates and macrovertebrates, silicified logs, macroscopic plant remains, and pol

TRACKING AUTHIGENIC MINERAL CEMENTS IN FOSSIL BONES FROM THE UPPER CRETACEOUS (CAMPANIAN) TWO MEDICINE AND JUDITH RIVER FORMATIONS, MONTANA

Autor: Lucas N. Weaver, Raymond R. Rogers, Anik K. Regan, Henry C. Fricke, Jeffrey T. Thole

Publikováno v: PALAIOS. 35:135-150

Previous studies have yielded mixed results as to whether authigenic mineral infill in fossilized bone tracks specific lithologies or depositional environments, with most suggesting weak to no correlation between infill composition and host lithofaci

On geologic timescales, plant carbon isotope fractionation responds to precipitation similarly to modern plants and has a small negative correlation with pCO2

Autor: Kristen M. Schlanser, Alexander J. Lowe, Jie Geng, James F. Basinger, Kevin E. Mueller, Henry C. Fricke, David R. Greenwood, Ellen D. Currano, Aaron F. Diefendorf, Christopher K. West, Herbert W. Meyer, Andrew Flynn, Daniel J. Peppe

Publikováno v: Geochimica et Cosmochimica Acta. 270:264-281

Leaf carbon isotope fractionation (Δleaf) is sensitive to environmental conditions and can provide insights into the state and evolution of leaf gas-exchange in response to climate and environment factors. In modern plants, water availability is the

Late Cretaceous fluvial hydrology and dinosaur behavior in southern Utah, USA: Insights from stable isotopes of biogenic carbonate

Autor: Henry C. Fricke, Joseph J. W. Sertich, Erica S.J. Evans, Victoria Crystal, Ian M. Miller

Publikováno v: Palaeogeography, Palaeoclimatology, Palaeoecology. 516:152-165

During the Late Cretaceous, North America was flooded by the epieric Western Interior Seaway. Mountain building events on the western landmass fed sediment to broad, low relief fluvial systems, which preserve rich dinosaur-bearing fossil assemblages.
