Multi-proxy assessment of brachiopod shell calcite as a potential archive of seawater temperature and oxygen isotope composition

Autor: T. Letulle, D. Gaspard, M. Daëron, F. Arnaud-Godet, A. Vinçon-Laugier, G. Suan, C. Lécuyer

Publikováno v: Biogeosciences, Vol 20, Pp 1381-1403 (2023)

Most of our knowledge of past seawater temperature history is based on δ18O values of calcium carbonate fossil shells. However, the determination of past temperatures using this proxy requires the knowledge of past seawater δ18O values, which is ge

Intra-skeletal variability in phosphate oxygen isotope composition reveals regional heterothermies in marine vertebrates

Autor: N. Séon, R. Amiot, G. Suan, C. Lécuyer, F. Fourel, F. Demaret, A. Vinçon-Laugier, S. Charbonnier, P. Vincent

Publikováno v: Biogeosciences, Vol 19, Pp 2671-2681 (2022)

Strategies used by marine vertebrates to regulate their body temperature can result in local variations, and the knowledge of these regional heterothermies is crucial for better understanding the thermophysiologies of extant and extinct organisms. In

Clumped isotope evidence for Early Jurassic extreme polar warmth and high climate sensitivity

Autor: T. Letulle, G. Suan, M. Daëron, M. Rogov, C. Lécuyer, A. Vinçon-Laugier, B. Reynard, G. Montagnac, O. Lutikov, J. Schlögl

Publikováno v: Climate of the Past, Vol 18, Pp 435-448 (2022)

Periods of high atmospheric CO2 levels during the Cretaceous–early Paleogene (∼ 140 to 34 Myr ago) were marked by very high polar temperatures and reduced latitudinal gradients relative to the Holocene. These features represent a challenge for mo
