We have a new Dr in #paleobotany! Congratulations to @thibault-durieux.bsky.social who successfully passed his viva. It was a great journey & he made the advising job very easy for
@petermoonlight.bsky.social, Carla Harper and I. Big thanks to the examiners Jenny McElwain & @sandyheth.bsky.social!

C'est la 29e Réunion des Sciences de la Terre à Montpellier toute la semaine 🌐🌋🦕 Demain après-midi je parlerai du changement de végétation dans la zone tropicale fin Carbonifère-début Permien avec l'exemple des flores de Graissessac & Lodève (session 8.1)⛏️ 🌿 #paleobotany #geosciences #paleontology

No FossilFriday again this week because after being sick and being away for fieldwork, I'm now on vacation and busy with some Very Serious Stuff 🍄 Paleobotany posts will be back next week!

And some of the fossils have arrived in Montpellier just in time for #FossilFriday 🎉
Most of them are stems with their tissues and cells preserved in 3D. They will be prepared as thin-sections & observed under the microscope to find out what plants they belonged to 🌿⛏️🔬 #paleobotany

And this #FossilFriday is the end of a very nice week looking for Devonian-Carboniferous fossil plants with @thibault-durieux.bsky.social, Chris & Carla 🌿⛏️🇮🇪 No photos of the actual finds for now 🤐 but one of our background views & some of our high tech field gear!

Some plant fossils, like this piece of Triassic wood, retain some organic matter of their cell walls 🌿⛏️ With a little bit of chemistry we can remove minerals & transfer the organic matter on a piece of cellulose acetate that can be observed under the microscope 🧪Happy #FossilFriday! #paleobotany

Tmesipteris, 1 of the 2 genera of Psilotaceae, growing on a tree fern trunk in New Zealand 🌿 With their apparently simple organisation, Psilotaceae were once considered as "remnants" of the earliest vascular plants, but recent analyses show that they are actually ferns.
Happy #FernFriday!

Today's fossil is a very tiny branching stem with preserved tissues - check the scale bar! 🌿⛏️🔬 It belonged to a lycopsid (= a clubmoss) that grew in what is now southern France during the early Carboniferous, about 350 million years ago #paleobotany #FossilFriday

Posidonia meadows are home to a diversity of organisms and absorb a loooot of CO2 🌿🌊🐟🦑 Posidonia oceanica form colonies that can live thousands of years and some may be among the oldest organisms on Earth 2/2

Summer vacation means visiting these beautiful underwater meadows of Posidonia oceanica seagrass 🤿🌿🌊 Seagrasses evolved in the Cretaceous from terrestrial flowering plants that adapted to life in the ocean

Happy #FossilFriday and #FernFriday ! This beautiful fossil leaf belongs to a #fern that was growing in what is now southern France during the late Carboniferous, about 300 million years ago 🌿⛏️

Day 3 started with a visit of the great paleontological exhibit at the museum in Lodève, with only fossils from the area, followed by a picnic near the Salagou lake & some vertebrate tracks in the red Permian layers.

Fieldtrip day 1: today we visited not 1 but 2 sites with fossil plants 🌿⛏️🤩 Here's a nice Stigmaria, the rooting structure of a lycopsid tree from the latest Carboniferous, a little over 300 million year ago. (and yes it is extremely warm 🌡️)
Large Stigmaria, it's a big axis bearing roots, some visible on the side and some just as scars on the axis
