Anatolia (Türkiye) during the late Eocene and the Eocene–Oligocene Transition: successive warming and cooling, aridification, and implications for the westward dispersal of Asian terrestrial mammals
Abstract. The Eocene–Oligocene Transition (EOT dated at ∼ 34 Ma) represents one of the most significant climatic shifts of the Cenozoic, marking the transition from the last warmhouse state to a coolh...

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 Master's research (now expanded with new collabs) is finally published! Together with Grégoire Métais, Emmanuel Gheebrant, Ni Xijun, @nilschabrol.bsky.social, and Marc Godinot, we describe exceptional new dental material of Coryphodon from Le Quesnoy (northern France, Eocene). @cr2p.bsky.social

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.

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....
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.

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

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.
