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 ...

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.

Breedon Hill [PDF]

, 2013
Breedon Hill forms one of the most prominent features in the landscape of north-west Leicestershire, standing up 50 m above the surrounding ground. That it has been a major landmark throughout recorded history is suggested by its name, which is derived ...

Late Carnian (Late Triassic) conodont and ammonoid paleontology of Wrangellia

, 2009
The development of conodont biochronology for the Triassic Period is hindered by the lack of understanding of the genus Metapolygnathus Hayashi, 1968a and, to a lesser extent, Carniepigondolella Kozur, 2003. Specimens of these genera collected at Klaskino Inlet, British Columbia are described as species populations of M.
