I don't know yet what the data will tell us about the dynamics of pedogenic carbonate growth. We've started a bunch of geochemical analyses on them, and on the water samples, which should tell us when they seasonally grow. Nothing on truffles, but I'm sure Pierre wouldn't have minded.

Many things have changed since we started the experiment. Pierre died in 2022, it was tough for the whole village. The trees kept growing and the nursery was abandoned for quite some time. Lately, a beekeeper installed his hives just next to my station, making sampling a little bit more challenging

I quickly left the truffles behind, because i realised that the ground was full of fresh pedogenic carbonates, so the nursery became my natural laboratory to study the growth of their growth.

The experiment started as a semi-joke with Pierre Nitard, my father's neighbour in Collias. "Could you predict when I get truffles in my oak nursery with climate data?" So I dug up some holes, set up some temperature and humidity sensor in the ground and in the air, and a rainwater collector.

Today, I celebrate the end of an experiment. It has been five years, during COVID times, that I set up this climate station in Collias, in southern France. Every first day of the month, I came here to get my rainwater sample. And today was the final sampling day. (1/n)

The first clumped isotope results from our platform at @cerege.bsky.social. Two long years of hardwork in the lab.
A new preprint from our research group is online!
In this paper, Paul Botté, PhD student in the project at @climatecerege.bsky.social, studied the evolution of continental environmental through the late Eocene and earliest Oligocene in central Anatolia.

Closing out my year with a journal editor shocker 🧵
Checking new manuscripts today I reviewed a paper attributing 2 papers to me I did not write. A daft thing for an author to do of course. But intrigued I web searched up one of the titles and that's when it got real weird...

So, did primates and rodents raft on vegetation debris to reach South America? This crazy hypothesis remains so far the only mechanism to reach South America during the Eocene. But why only at 40 Ma, and how? Questions that we will try to answer in the next few years -- more on this topic soon (n/n)

Leny showed that primates and rodents could have hopped along archipelagoes from Balkanatolia to North Africa. But there is no viable archipelago to reach South America from Africa via island hopping, even in the most extreme scenarii (3/n).

In this paper, Leny Montheil, postdoc at @climatecerege.bsky.social within the ERC project @dispersal-erc.bsky.social, reconstructed at high resolution the paleogeography of the Atlantic and Neotethyan domain 40 Million years ago, using the most recent plate reconstructions. (2/n)

🚨New paper alert🚨 40 million years ago, anthropoid primates and rodents dispersed from East Asia to Africa and South America, across two wide oceans (the Neotethys and the Southern Atlantic). So Which way did they pass? @dispersal-erc.bsky.social (1/n)

Clay suggests that this isolation was associated with a moderate uplift generated by an episode of lithospheric foundering, tens of millions of years before what is commonly proposed in the area. This scenario opens new interpretative ways for the rich geomorphological history of Anatolia! (n/n)

In this paper, Clay reconstructed the drainage history of the Cankiri Basin in central Anatolia following the final closure of the seaways straddling across Balkanatolia. He showed that quickly after the final closure, the Cankiri basin got completely isolated (2/n)
