New paper out on the formation mechanism of cameral deposits in orthoceratoid cephalopds! This topic has been debated for more than 150 years and we now finally have a satisfying solution 🥳

Nice view of @ruhr-uni-bochum.de campus this evening, though the picture looks a lot more dramatic than it was in reality.

Just bridged my account from Mastodon to Bluesky using @bsky.brid.gy so you can now follow me on either platform! Still relatively new to all of this, trying to figure things out as I go ...

Check out our new article introducing phylogeochemistry, combining #macroevolution with #geochemistry. We investigated evolutionary patterns of element ratios in #belemnites through the Jurassic and Cretaceous.
