Gradual warming prior to the end‐Permian mass extinction
; ; ; ; ; ; ; (Palaeontology, 2022-09-06)
The biggest known mass extinction in the history of animal life occurred at the Permian–Triassic boundary and has often been linked to global warming. Previous studies have suggested that a geologically rapid (<40 kyr) ... -
Teeth of Past and Present Elephants: Microstructure and Composition of Enamel in Fossilized Proboscidean Molars and Implications for Diagenesis
Białas, Nataniel; Prymak, Oleg; Singh, Ningthoujam Premjit; Paul, Debajyoti; Patnaik, Rajeev; (Geochemistry, Geophysics, Geosystems, 2021-04-22)
Enamel as hardest biological tissue remains unaltered for millions of years and is therefore an excellent archive for studies on paleodiet, paleoecology, paleoclimate, paleoenvironment, biomechanical, and evolutionary ... -
Tourmaline Reference Materials for the In Situ Analysis of Oxygen and Lithium Isotope Ratio Compositions
Wiedenbeck, Michael; Trumbull, Robert B.; Rosner, Martin; Boyce, Adrian; Fournelle, John H.; Franchi, Ian A.; Halama, Ralf; Harris, Chris; Lacey, Jack H.;; Meixner, Anette; ; Pogge von Strandmann, Philip A.E.; Spicuzza, Michael J.; Valley, John W.; Wilke, Franziska D.H. (Geostandards and Geoanalytical Research, 2020-11-07)
Three tourmaline reference materials sourced from the Harvard Mineralogical and Geological Museum (schorl 112566, dravite 108796 and elbaite 98144), which are already widely used for the calibration of in situ boron isotope ... -
Variability in tree water uptake determined with stable water isotopes in an African tropical montane forest
Hahn, Melanie; Jacobs, Suzanne Robin;; ; (Ecohydrology, 2021-02-08)
Ecohydrological processes in tropical rainforests are insufficiently understood, and existing studies yield contradictory results. We investigated relative contributions of different soil depths to tree water uptake of 83 ...
