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 ...

Influence of water-rock interaction on stress sensitivity of organic-rich shales: A case study from Longmaxi formation in the southeast area of Chongqing

Youqicang pingjia yu kaifa, 2019
The production of shale gas is a complex and multiscale process that spans a variety of scales and goes through a variety of mass transfer mode. The stress sensitivity of each path has an important influence on the mass transfer of shale gas.
