The Earliest Feathers from the Lower Cretaceous Dabeigou Formation of North Hebei: Implications for the Early Evolution of the Jehol Biota

Integrative Zoology, EarlyView.
This study reports two isolated feather fossils from the Lower Cretaceous Dabeigou Formation in northeastern China. Morphological analyses identified them as the earliest known feathered theropods (potentially including avian) in the Jehol Biota. This finding reveals a complex ecosystem at the dawn of the Jehol Biota, bridging the temporal and faunal ...

Did plate tectonic changes lead to the emergence of hominid bipedalism?

Frontiers in Environmental Archaeology
When early hominids began walking upright around 6 Ma, their evolutionary course took a sharp turn. The new posture enabled physical and mental developments that had not been possible before.

The Biggest Plates on Earth: Plate Tectonics [PDF]

In this lesson, students investigate the movement of Earth's tectonic plates, the results of these movements, and how magnetic anomalies present at spreading centers document the motion of the crust. As a result of this activity, students will be able to

Brittle Structural Control and Fluid Progress of the Jinqingding Gold Deposit: Implications for Epizonal Gold Mineralization

Acta Geologica Sinica - English Edition, EarlyView.
ABSTRACT The Jinqingding gold deposit in eastern Jiaodong is a significant gold mineralization within the Muping–Rushan metallogenic belt. This study integrates structural analysis and trace element geochemistry of sulphides to elucidate ore‐controlling mechanisms and metallogenic models.

Indigenous‐Led Adaptation to Complex Climate Risks in New Ireland, Papua New Guinea

Asia Pacific Viewpoint, EarlyView.
ABSTRACT Pacific Island peoples have long histories of adapting to environmental changes, but recent climate change is now driving complex risks that unfold within rapidly shifting societal and environmental contexts. This study investigates how remote Indigenous communities in New Ireland, Papua New Guinea, experience and want to respond to complex ...

Fault slip-rate variations during crustal-scale strain localisation, central Italy [PDF]

, 2002
Rates of plate motion are generally uniform over 10–102 Myrs timescales. Faults between tectonic plates might, therefore, be expected to show temporally-uniform slip-rates if the same number of faults remain active. For an extending region of the Eurasia-

Luminescence dating of coastal deposits from the Chanthaburi Plain, Thailand

Boreas, EarlyView.
The ongoing global sea‐level rise urges us to better understand the dynamics of coastal processes for predicting future changes. Sedimentary deposits reflect past coastal environments but require precise chronological data to place evidence into a temporal context.
