3D Quantification of Subsidence During Pyrenean Retro‐Wedge Initiation: Role of Structural and Thermal Inheritance on Hyperextended Margin Inversion (Aquitaine Basin)

Terra Nova, EarlyView.
ABSTRACT We present novel 3D subsidence data enabling vertical movements' quantification during the early formation of the Pyrenean retro‐wedge. From Cenomanian to Turonian times, subsidence is relatively low (~26 ± 10 m/Myr), corresponding to a brief 10 Myr thermal re‐equilibration of the European lithosphere following the hyperextended rift episode ...

Triassic Echinoids

Smithsonian Contributions to Paleobiology, 1977
Although 142 species of Triassic echinoids have been reported, only 24 are based on sufficient material to permit reliable generic identification. These species are redescribed and illustrated. Twelve of them are from the St. Cassian Beds in the Italian Dolomites.

Evaluating Bayesian Morphological Clocks for Estimating a Dated Phylogeny in a Relict and Fossil‐Rich Family of Wasps (Hymenoptera, Chrysidoidea)

Zoologica Scripta, EarlyView.
ABSTRACT In recent years, a wide array of tools originally developed for molecular dating analyses has been adapted for use within a morphological clock perspective. This is of paramount relevance for taxonomic groups that cannot be sampled in forms suitable for DNA extraction.

Characteristics and controlling factors of shale oil reservoirs in the seventh member of Triassic Yanchang Formation, western Mahuangshan area, Ordos Basin

Shiyou shiyan dizhi
The seventh member of the Triassic Yanchang Formation (Chang 7) in the Ordos Basin is abundant in shale oil resources. However, there are significant differences in reservoir characteristics between the basin margin and the basin center.
