Eustatic and tectonic controls on mixed carbonate‐siliciclastic ramp deposits in the South Pyrenean foreland basin: The Eocene Alveolina Limestone

open access: yesThe Depositional Record, EarlyView.
The lower Eocene Alveolina Limestone records the global early Eocene transgression, but is equally affected by tectonic movements of the Montsec active thrust located in its hangingwall. Tectonic movements and the early Eocene transgression facilitated a detrital provenance shift in the southern Pyrenean foreland from a southern provenance in the ...

Trace elements, rare earth elements and isotopes of poorly preserved fossils from lower Cretaceous carbonates (Eastern Black Sea): Implications for early diagenetic alteration

open access: yesThe Depositional Record, EarlyView.
Analysing Rare Earth Elements (REEs) and other trace elements together with stable isotope data in poorly preserved belemnites can provide valuable insights into early diagenetic pathways, water‐interaction processes, and even potential redox conditions.

Declining Volatility, a General Property of Disparate Systems: From Fossils, to Stocks, to the Stars

open access: yes, 2013
There may be structural principles pertaining to the general behavior of systems that lead to similarities in a variety of different contexts. Classic examples include the descriptive power of fractals, the importance of surface area to volume ...

Contributions to Canadian paleontology

open access: yes, 1969
Chaetetipora ellesmerensis new species and Sibiriolites sibiricus Sokolov are described from Judge Daly Promontory and M'Clintock Inlet. Both species are from rocks of Richmond (Ashgill) age.

The Cenomanian–Turonian boundary interval in the Western Canada Foreland Basin: Stratigraphy, geochemistry, geochronology and sea‐level changes recorded in expanded and condensed clastic successions

open access: yesThe Depositional Record, EarlyView.
Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.

Black shale deposition during the Early Jurassic: Geochemistry of Pliensbachian and Toarcian sedimentary rocks of the Hunzen Well, Hils Syncline, Northwest German Basin

open access: yesThe Depositional Record, EarlyView.
Our research uses a multidisciplinary approach, including organic and inorganic geochemistry, biostratigraphy, carbon isotope geochemistry and organic petrography to reconstruct depositional conditions and organic matter accumulation during the Pliensbachian and Toarcian.

Single‐cell sequencing reveals potential novel insights into appendage‐patterning and joint‐development in a spider

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Jointed appendages represent one of the key innovations of arthropods, and thus understanding the development and evolution of these structures is important for the understanding of the evolutionary success of Arthropoda. In this paper, we analyze a cell cluster that was identified in a previous single‐cell sequencing (SCS ...

The division of food space among mammalian species on biomes

open access: yesEcography, EarlyView.
Understanding how species' ecological partitioning functions across biomes is fundamental to macroecology and conservation biology. Here, we examine the global distribution of dietary strategies in terrestrial mammals, focusing on how biome specialization modulates trophic diversity and structure at a broad geographical scale.
