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).

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!

I remember Jeremy McCormack presenting this nice #zinc #isotope dataset @ EGU this year showing how #Miocene sharks had diverse roles in the marine foodweb. Great study, glad to see it found a nice home in EPSL!

🗨️ F*ck off, ISR, the new #Isotope of the Nazis! Your entire so called parliament has been involved in #warcrimes and #CrimesAgainstHumanity - since 1948, the world is no longer interested in your sick statements! Everybody KNOWS that you are not representing the Jewish interests!
Kind greets from a #German #resistance fighter against fascists and anti-humanists!

This phenomenal study by Alexandre Pohl and colleagues investigates in a very comprehensive way how estimates of the #oxygen #isotope composition of seawater bias our #climate reconstructions, one of the most important uncertainties in #paleoclimate research.

Amino acid-specific #isotope analysis is really shaping up like a very promising tool for #paleo #ecology and #environmental studies!

A very cool study using #clumped #isotope measurements in #oyster shells from the Early #Cretaceous showing high and variable #seasonality in response to climate changes caused by atmospheric #CO2 shifts. #mollusk shells again demonstrated as useful climate archives!

#isotope enabled #climate #modelling brings reconstructions and models together more closely for the Late #Cretaceous, a warm period with high #greenhouse gas concentrations in the atmosphere (and dinosaurs!)

Great paper by Gray and Brandon @G-cubed @Agu on the #clumped #isotope #temperature relationship in gar fish scales. I especially enjoyed reading about the treatment of effective vs mean temperatures and seasonal bias in these calibration studies.

"Good god! Do you realize what you've done?"
"Not quite."
"You've duplicated the pope! Except the new one is a bit heavier."
"True. That's because he is an isopope."
