Ammonites survived the end-Cretaceous mass extinction. I always learned that they went extinct. Very cool finding!

I’m currently looking for a new professional opportunity in the Bremen area – maybe you can help me with that. If you hear of any suitable positions or just want to reconnect, I’d be happy to hear from you or see a comment below.

But this is all testing the limits of correlations and the precisions of the dating techniques, as Westerhold et al highlight in this paper: agupubs.onlinelibrary.wiley.com/doi/10.1029/...
Timing Is Everything
Timing is important for comprehending Earth's biological and climatic processes shaping evolution, extinction, and recovery Key climate proxy records of the last 100 million years are not suffici...

How did global air temperatures vary before 1850?
We can now answer this from direct instrumental observations.
The new GloSAT dataset is under review!

Hello, I am new to this space and want to introduce myself the next few weeks.
After my Geoscience Master in Bremen, I started my PhD project march 2020, 2 weeks before lockdown as I use to say 😅, at NIOZ on the beautiful island of Texel 🏖️🦭
