Proud to be on this publication in GCA by Barbora Krizova et al. We show #clumped #isotope reordering in #Cretaceous rudist bivalves is location-specific. Understanding burial history is essential for selecting shell material for #paleoclimate #reconstructions. www.sciencedirect.com/science/arti...

Effects of mineralogy on Δ47 and Δ48 of carbonate-derived CO2 below analytical resolution Due to the lack of direct methods capable of determining the abundance of isotopologues containing multiple heavy isotopes within the crystal lattice,…

The #clumped #isotope paleo temperature proxy is one of the most reliable means of temperature reconstruction in #geology. This new study shows that it can be applied equally on various carbonate minerals (calcite, aragonite, dolomite, witherite and siderite).

Living on the edge: Response of rudist bivalves (Hippuritida) to hot and highly seasonal climate in the low-latitude Saiwan site, Oman Abstract. Earth’s climate history serves as a natural laboratory for testing the effect of warm climates on the biosphere. The Cretaceous period featured a prolonged greenhouse climate characterized b...

Check out our latest #preprint in which we use a combination of #clumped and #oxygen #isotope measurements to reconstruct extreme summer temperatures experienced by #fossil #rudist bivalves from the Late #Cretaceous in Oman. All feedback is welcome!
