Finally, climatic reconstruction methods (Coexistence Approach and CREST) indicate a warm-temperate climate with hot summers.
This support the idea that faunal endemism in Balkanatolia was rather driven by insular isolation, rather than climatic or environmental barriers.

Notably, we document the first occurrence of Corsinipollenites (Onagraceae pollen) and Azolla ferns from the Lutetian of Türkiye.

This is one of the first inland-deposited palynofloras from the Eocene of Türkiye. It is dominated by swamp-freshwater taxa, including Cupressaceae, Ludwigia (Onagraceae), and ferns.

The first article from my PhD has just been published in JAES: "Lutetian swamp-freshwater palynoflora from Bultu-Zile (central Anatolia, Türkiye): implications for Eocene ecosystems of Balkanatolia".

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.

🎙️ First episode of a series of interviews with the scientists involved. Stay tuned — more interviews coming soon!
Philippe Taquet, chasseur de dinosaures et ancien directeur du Muséum national d’histoire naturelle, est mort
Today, we organized a vulgarisation workshop about paleopalynology at the Musée Espace Gaïa in Montereau-Fault-Yonne for the "Fête de la Science"! Rafael Cabral, Adele Giobbini and myself (with the help of @mathildelp.bsky.social) presented 3D printed pollen grains to the public.
Last days of fieldwork in Anatolia, with Serkan Akkiraz, Paul Botté and @benjaminraynaud.bsky.social! Exploring the Sivas Basin to date the onset of the modern steppe landscape with various stratigraphic and paleobotanical tools. Part of the @dispersal-erc.bsky.social project!
Paul Botté from @climatecerege.bsky.social and @benjaminraynaud.bsky.social from @cr2p.bsky.social presenting their work on #balkanatolia paleoenvironments today at the yearly conference of Turkish Earth scientists in Yozgat. Back to fieldwork tomorrow!
Hi, actually the site is underwater out of the field campain (July). So, there are no visits during the rest of the year. But you can see some of the specimens in the Museum in Angoulême! The leader of the field from our lab (CR2P) is Ronan Allain.
Looking for pollen, vertebrate fossils and pedogenic carbonates in Anatolia! With @benjaminraynaud.bsky.social, Paul Botté, @dispersal-erc.bsky.social
First day of the third field trip to Turkey for Paul Botté and @benjaminraynaud.bsky.social. One week to collect their last samples before their ultimate task: writing their dissertation!
If you want to follow each field campain: here is the blog of the paleoartist Mazan, working on the site of Angeac-Charente (it's written in French)

Nice day of fieldwork in the Luberon Geopark, trying to date some of their iconic fossil sites. With Pauline Coster, @benjaminraynaud.bsky.social, and many others from @dispersal-erc.bsky.social
@benjaminraynaud.bsky.social presenting his PhD results at @cerege.bsky.social today ! Benjamin works on the evolution of ecosystems during the dispersal events we investigate in the project via pollen analysis.

Simplified flowchart illustrating generalised steps in palaeobiological research processes and the various factors that introduce inequity with regard to data collection, storage, study, analysis, publication, and reuse.
Delighted to share our paper on data equity in #palaeobiology as part of Paleobiology's 50th anniversary issue 🥳
We look at how palaeo data is collected, stored, curated & shared, and how equity in these processes is crucial for our field's future (1/n) 🧪⚒️

We show that endemism started at least by 47 Ma, and possibly much earlier, in the Paleocene. Older sites are so far lacking, but we expect to publish some in the next few years (stay tuned!). With @benjaminraynaud.bsky.social @mustafayk.bsky.social and many others at @climatecerege.bsky.social
🚨New paper alert!🚨 A long and precise stratigraphic and geochronological study led by Leny Montheil to better refine the time of formation of Balkanatolia, this strange biogeographic province that we have been studying for a decade now. (1/n)

#PaleoSky
Amazing workshop last week in Arles, focused on how integrating geological and paleoclimatological constraints in phylogenetic and biogeographic reconstructions! 11 countries, 55 people, and 3 days of talks and brainstorming with a balanced group of biologists, geologists and climatologists.
Welcome to @benjaminraynaud.bsky.social on the Blue place! Benjamin in a PhD student in Paleobotany, working with us on understanding the changes in ecosystems which could have favored the dispersal of primates and ungulates out of Asia during the Eocene.
