Warmer paleotemperatures for terrestrial ecosystems [PDF]

open access: yesProceedings of the National Academy of Sciences, 2002
Floras of predominantly wet-soil environments show a greater than expected proportion of toothed leaves, affecting the outcome of leaf physiognomically based temperature estimates. New analyses of foliar physiognomy of plants growing in predominantly wet soils in modern forests suggest that current methods of inferring paleotemperatures from fossil ...

Paleoclimatic Reconstruction Based on the Late Pleistocene San Josecito Cave Stratum 720 Fauna Using Fossil Mammals, Reptiles, and Birds

open access: yesDiversity, 2023
Advances in technology have equipped paleobiologists with new analytical tools to assess the fossil record. The functional traits of vertebrates have been used to infer paleoenvironmental conditions.

Modelling of the Paleozoic and Mesozoic foci of hydrocarbon generation to assess their role in petroleum accumulations formation belonging to the Devonian and Carboniferous section (the Tomsk Region study) [PDF]

open access: yesНефтегазовая геология: Теория и практика, 2021
This paper performs coupled paleotemperature modelling of foci of hydrocarbon generation in sedimentary basins: the “present” Jurassic-Cretaceous basin and the Silurian, the Devonian and Carboniferous “paleobasins” in the territory of the Ostanin and the

Fast and pervasive diagenetic isotope exchange in foraminifera tests is species-dependent

open access: yesNature Communications, 2022
Paleoclimate reconstructions commonly use oxygen isotope compositions from fossil foraminifera tests as proxies. Here, the authors show that these tests exchange O-isotopes with surrounding fluids, with implications for paleotemperature records.

A Late Miocene Terrestrial Temperature History for the Northeastern Tibetan Plateau's Period of Tectonic Expansion

open access: yesGeophysical Research Letters, 2019
During the Late Miocene, the climate patterns and ecosystems of continental land masses experienced crucial transitions, but whether the principal driver was regional tectonic forcing or a decline in CO2 concentrations remains debated.

Forecast of petroleum bearing of the pre-Jurassic section belonging to Bakchar depression using the geothermal energy data (Tomsk region) [PDF]

open access: yesНефтегазовая геология: Теория и практика, 2021
Based on paleotemperature modeling carried out for the Lower Jurassic Togur Formation and determining of the relative density of its generation potential, a zoning of the studied area was realised.

A Kinetic Difference Between 12C‐ and 13C‐Bound Oxygen Exchange Rates Results in Decoupled δ18O and Δ47 Values of Equilibrating DIC Solutions

open access: yesGeochemistry, Geophysics, Geosystems, 2018
Accurate determination of paleotemperatures using carbonate δ18O and Δ47 values rely upon the assumption that the minerals in question formed close to expected isotopic equilibrium with their environment.
