Le 18 novembre, sous le marteau des enchères, la France risque de perdre à jamais un dinosaure unique au monde — au seul motif qu’aucune loi ne protège les fossiles. Le CR2P dénonce cette situation ! @mnhn.fr @cnrsecologie.bsky.social @recherche.mnhn.fr @sorbonne-universite.fr

🚨new paper alert🚨the first paper of PhD student Paul Botté and the first dataset of clumped isotonic data acquired at @cerege.bsky.social by @r0seturqu0ise.bsky.social! Investigating the late Eocene - Oligocene climate evolution in Balkanatolia with a new terrestrial record. doi.org/10.5194/cp-2...

A new paper from the @dispersal-erc.bsky.social project! In this study, we investigated how embrithopods, these massive herbivorous mammals who once throve in Africa, succeeded to cross the Neotethys and diversified on Balkanatolia (1/n) doi.org/10.2110/palo...

My first paper is out in @methodsinecoevol.bsky.social : doi.org/10.1111/2041... With @idriss-pelletan.bsky.social and @paulineprovini.bsky.social, we developed SOUPE, a new method and R package to evaluate the phylogenetic representativeness of taxonomic samples, and help create optimized samples.

🎙️ Our first interview is out! Meet Leny Montheil, geodynamicist and paleogeography specialist, as he takes us back to the Eocene to explore how primates dispersed across a changing world. ▶️ Watch it now on YouTube youtu.be/bjzU_UIXseU

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. egusphere.copernicus.org/preprints/20...

How did mammals cross oceans millions of years ago? Our first video introducing the ERC-funded DISPERSAL project is live on YouTube 🎉 👇 Check it out! youtu.be/COdGQYkdraw 🎙️ 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!

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!

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.

Digitizing collections to unlock the full potential of palynology: A case study with the Smithsonian palynology collection Carlos Jaramillo, Surangi W. Punyasena, Daurys de Alba, Roxana Alveo, Angelica Arcila, Jorge Bermudez, Jonatan Bustos et al nph.onlinelibrary.wiley.com/doi/10.1002/...

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) 🧪⚒️ doi.org/10.1017/pab....

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) www.sciencedirect.com/science/arti...

Tomorrow afternoon, Paul Botté @climatecerege.bsky.social will have his #EGU25 poster presentation: doi.org/10.5194/egus... With @alexislicht.bsky.social and @r0seturqu0ise.bsky.social. With also @benjaminraynaud.bsky.social outside of CEREGE. (5/10) 🧪 ⚒️ #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.
