Species Diversity of Radulopecten (Pectinoidea, Bivalvia) in the Jurassic Seas of the Northern Central Neotethys: Reconsidering the Paleontological Information

Geosciences
Radulopecten Rollier, 1911 was a common bivalve genus in the Middle–Late Jurassic seas of the northern Central Neotethys. The present work offers measurements of the species diversity dynamics of this genus after reconsideration of the species names and ...

New fossil unveils the dentary anatomy of the rare lepidosauromorph Cargninia enigmatica from the Upper Triassic of Southern Brazil

The Anatomical Record, EarlyView.
Abstract Nowadays, Lepidosauria is a diverse group represented by squamates and the rhynchocephalian tuatara. However, their origins date back to the end of the Permian Period, when the stem lineages Lepidosauromorpha and Archosauromorpha diverged. Within the lepidosauromorph stem lineage, a few species have been described with unstable phylogenetic ...

Building phenotypic character matrices for phylogenetic inference: exploration of 35 years of practice

Biological Reviews, EarlyView.
ABSTRACT Recent methodological development in phylogenetic inference has focused predominantly on molecular data. However, renewed interest in other data types, particularly morphological data, has followed from the increased recognition of the power of total evidence and tip‐dating approaches, including fossil data, for inference of time‐scaled trees ...

Advancing Environmental Sustainability Through Wind Energy, Green Technology, and Fintech: A Quantile Perspective From Germany's Low‐Carbon Transition

Geological Journal, EarlyView.
The current study examines the role of Fintech, wind energy, and green technology in determining environmental suitability in Germany from 2000 to 2024. The study employs time series econometric methods to estimate the QQR and QR techniques. The positive effects of wind production, FinTech, Natural Resources and green technology on environmental ...

Discovery of an Extensive Deep-Sea Fossil Serpulid Reef Associated With a Cold Seep, Santa Monica Basin, California

Frontiers in Marine Science, 2019
Multibeam bathymetric mapping of the Santa Monica Basin in the eastern Pacific has revealed the existence of a number of elevated bathymetric features, or mounds, harboring cold seep communities.

Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

Geological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Thermochronologic Constraints on the Extensional History of the Ibex Hills, Southeastern Black Mountains, Death Valley, California

Geological Journal, EarlyView.
A. Modeled T‐t paths for samples in the northern Ibex Hills, showing steady cooling throughout much of the Cenozoic, until rapid Miocene cooling. B. Weighted mean paths for each sample in this study. Note that all show a rapid cooling event at or just after 10 Ma, which is interpreted to represent exhumation as a result of regional extenstion ...

Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen

Geological Journal, EarlyView.
By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

The Evolution of Equid Monodactyly: A Review Including a New Hypothesis

Frontiers in Ecology and Evolution, 2019
The traditional story of horse evolution is well-known: over time, horses became larger, they attained higher-crowned teeth, and they changed from having three toes (tridactyly) to a single toe (monodactyly). Evolution is often perceived as a progression

The Energy Dilemma: Does Energy Security Risk and Renewable Energy Affect Fossil Material Footprint? Policy Framework for Securing SDGs

Geological Journal, EarlyView.
Energy security risk has a positive impact on material footprint. Renewable energy consumption reduces material footprint. ABSTRACT Following a high economic growth path, the group of G7 economies is found to be utilising more and more material, causing a material footprint (MF), which in turn contributes to pollution.
