Cenozoic stratigraphic correlation and the lower limit of Quaternary in Guanzhong Basin

地质科技通报, 2021
Thick Cenozoic sediments in Guanzhong Basin provide excellent geological records for the study of the regional tectonics, sediment environment evolution and paleoclimate change.However, there are still controversies about the Cenozoic stratigraphic ...

Geochemistry and petrogenesis of volcanic rocks from Daimao Seamount (South China Sea) and their tectonic implications [PDF]

, 2015
The South China Sea (SCS) experienced three episodes of seafloor spreading and left three fossil spreading centers presently located at 18°N, 17°N and 15.5°N.

The relationship between form and function of the carnivore mandible

The Anatomical Record, EarlyView.
Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...

Sedimentation and subsidence history of the Lomonosov Ridge [PDF]

, 2006
During the first scientific ocean drilling expedition to the Arctic Ocean (Arctic Coring Expedition [ACEX]; Integrated Ocean Drilling Program Expedition 302), four sites were drilled and cored atop the central part of the Lomonosov Ridge in the Arctic ...

Cenozoic geochronology

Geological Society of America Bulletin, 1985
We present a revised Cenozoic geochronology based upon a best-fit to selected high-temperature radiometric dates on a number of identified magnetic polarity chrons (within the Late Cretaceous, Paleogene, and Neogene) which minimizes apparent accelerations in sea-floor spreading.

Histovariability and fossil diagenesis of Pissarrachampsa (Pseudosuchia, Notosuchia, Baurusuchidae) from the Upper Cretaceous of Southeast Brazil

The Anatomical Record, EarlyView.
Abstract Notosuchians were key components of western Gondwanan Cretaceous ecosystems in terrestrial predator niches and exhibited remarkable taxonomic and ecological diversity. Previous research has explored their physiology, metabolism, and histology, revealing varied growth patterns and life history strategies.

Geochemical analysis of Cenozoic fossil conifers at high latitudes: Implications for molecular preservation and environmental change [PDF]

, 2010
Fossil materials record ancient life and their adapted environment. Arctic plant fossils are critical for our understanding of the Earth’s paleoenvironment when high latitudes were under ice-free conditions.

Jurassic–Early Cenozoic Tectonic Inversion in the Qilian Shan and Qaidam Basin, North Tibet: New Insight From Seismic Reflection, Isopach Mapping, and Drill Core Data

Journal of Geophysical Research: Solid Earth, 2019
The pre‐Cenozoic structural pattern of Asia has had a strong impact on the localization and propagation of the Cenozoic deformation that gave birth to the Tibetan Plateau.
