Office with a view ❄️

The Jardin des Plantes @mnhn.fr is so amazing when there is snow.
What a perfect gift for its 400th anniversary !

#snow #museum #paris

Teaching tropical #wood anatomy today. Look at this gorgeous #Andira (Fabaceae) and this nice aliform-confluent parenchyma pattern !

I only took the picture with my phone. It's all visible with a naked eye.

This is the third paper from my thesis 👏. This time focusing on paleobiogeographical interpretations with 6 unique species.

Fossil wood is a treasure trove of information waiting to be unearthed 🌳.

Many thanks to @annbot.bsky.social for this thread

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.

The annual #Orchid exhibition at the Grandes Serres of the @mnhn.fr. Always delightful 😊

The base of the trophy is a thick section of a Juniperus stump, on the left side stands a ring made of Eucalyptus and in the center of the ring is a fruit of Dipterocarpus.

This is my PhD trophy (a tradition in our team) and I LOVE it! I've indeed worked partly on Dipterocarpaceae... which explains the fruit.

A tropical forest seen from the canopy with a river delta in the horizon and a big monsoon cloud. Blossoming tree in the middle, a Dipterocarpus on the left with fruits and an Artocarpus with fruit on the right.

Not a fossil for #fossilfriday but another #watercolor illustration from the Middle Miocene of Myanmar done by my mother. You can see Dipterocarps in full bloom, a Dipterocarpus and an Artocapus. #paleoart

Fossil wood fragments of different shapes and colours arranged in a rosette pattern.

For #FossilFriday here is a mandala of some raw fragments of fossil wood. You have Fabaceae, Moraceae and Dipterocarpaceae here.

What is the best collaboration I had ? My mother, who made this watercolor landscape illustration of the Paleocene of Myanmar for one of my thesis chapters 🥳

Perfectly ripe persimmon (kaki, in french) showing the vascularisation. I found it fascinating... and delicious !

Thanks for fixing it ;)

Here is an addition to the low-latitude #paleocene fossil record of palm stems and wood.
We highlighted the long-lasting presence of some taxa in Myanmar as well as a diversity of anatomical features similar to the Indian Deccan flora or present-day tropical florae.

First fossil woods and palm stems from the mid‐Paleocene of Myanmar and implications for biogeography and wood anatomy Premise The rise of angiosperm-dominated tropical rainforests has been proposed to have occurred shortly after the Cretaceous–Paleogene transition. Paleocene fossil wood assemblages are rare yet pro...

Here is the my second thesis paper.

We highlight the abundance of wet evergreen taxa likely related to higher precipitations and a stronger monsoon regime.

Fossil wood from the lower Miocene of Myanmar (Natma Formation): palaeoenvironmental and biogeographic implications The palaeobotanical record of Myanmar (Burma) is poorly documented despite its importance for understanding the evolution of Asian monsoonal ecosystems through time. Here, we describe 20 taxa of fossi...

New medium, new introduction to my work. Here is the first paper I published from my thesis.

"Jurassique en voie d’illumination" au Jardin des plantes de Paris : dans la peau d'un paléontologue à la découverte de la biodiversité Pour la sixième édition de son parcours "En voie d’illumination", le Muséum national d’histoire naturelle propose un voyage à la découverte de la période jurassique. Une époustouflante féerie lumineus...

Jurassique en voie d’illumination au jardin des plantes. Beaucoup de scientifiques du CR2P ont participé à cette exposition, dont les paléobotanistes!

The #Ginkgo at the #JardinDesPlantes in Paris are gorgeous this year too. Their bright golden leaves really stand out.

Hi everyone! For my first post here, I'd like to share this beautiful Williamsonia from the "Jurassique en voie d'Illumination" exhibition at the Muséum national d'Histoire naturelle in Paris! 🗼

I also called on the Herbonautes community to computerize the #Dipterocarpaceae labels of the Paris #herbarium #mnhn. This is indeed a powerful and exciting initiative.

For #FossilFriday, a picture of @nicolasgentis.bsky.social surrounded by pictures of fossil wood material from his PhD thesis (a huge xylotheque on paper, from the fossil forests of Myanmar)

I was able to retrieve some of the work but had to navigate between tangeled words and letters.

I can finally say I experienced one of the computer crashes that MUST happen right before submitting the thesis manuscript. The pdf is corrupted AND the original file has disappeared. 😬😱

Hi, I'm new to the BluePlace. Let's talk about paleobotany and fossil wood !
