#FossilFriday _Paramatonia rafaherbstiana_, just published fern from the Lower Cretaceous of Patagonia

#FossilFriday The conifer _Podocarpoxylon mazzonii_ from the uppermost Cretaceous of Patagonia, in three sections: radial longitudinal, tangential longitudinal, and transverse. Yes, it has multiseriate (up to pentaseriate) rays.

Permian (~260 million year old) fossil wood of Glossopteris and its delicious scale bar to celebrate #FossilFriday! #paleobotany 🍃⛏️🍫

Clusia major (Trinidad & Lesser Antilles) has dangling aerial roots that eventually touch the earth—not surprising for a hemiepiphyte that starts life in a tree (or, as here, on a cliff). What is surprising is that sometimes shoots grow from the roots. #Clusiaceae #TropicalBotany #Botany 🌾🧪🌱

Conifers. Cones from the genera: Thuja, Thujopsis, Chamaecyparis, Pinus, Picea, Cypressus, Callitris, Taxodium, Tsuga, Cryptomeria, Calocedrus, Tetraclinis, Larix, Metasequoia

November 2025 is a special month for @ijpsjournal.bsky.social, as the first issue of @ijpsjournal.bsky.social was published in November 1875. To celebrate our 150th, we've solicited short appreciations of our editors’, authors’, and readers’ favorite papers. See them all here: tinyurl.com/ym2ddx5y

🍃 Science out of the lab and into the night 🌙 Honoured to present our research on plant diversity at #MEDNIGHT ! #PlantDiversity #PlantScience #PublicEngagement #ResearchOutreach

You know what's cool too ? Plants ! We had 3 of them this year : the cretaceous conifer Sequoites🌲, a really close relative of our modern seed plants called Runcaria🌾, and Asterophyllites, which is the given name of the leaves from carboniferous tree-size horsetails like Calamites🌿

🍎 C’est la saison des pommes ! Saviez-vous que pour les botanistes, ce fruit emblématique… n’est pas vraiment un fruit ? En effet, la partie correspondant à ce qui était l’ovaire de la fleur se limite en réalité au trognon. Ce que nous mangeons est en fait un dérivé du réceptacle floral.

🌲 Very happy to share our new study on where, when, and why trees die across the range of 3 major southern US pines: Pinus taeda, P. palustris, and P. elliottii (loblolly, longleaf, and slash pine). 🔗 doi.org/10.1111/geb.70141 @ird-fr.bsky.social @umramap.bsky.social @ulbrecherche.bsky.social 🧵1/9

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!

🇨🇵 @thibault-durieux.bsky.social présentera ses résultats de thèse jeudi 30 à 11h à @umramap.bsky.social & en visio. La présentation sera en français avec diapos en anglais 🌿⛏️ 🇬🇧 Thibault will also give an English version of this talk on November 14 at Trinity College Dublin & online. #paleobotany

🌳 New paper out in Ecology Letters! 🌱 Our latest study, led by Lukas Magee, shows that the “legacies” of trees continue to shape forests long after they die. onlinelibrary.wiley.com/doi/10.1111/... #Ecology #Forests #Biodiversity @umramap.bsky.social @ird-fr.bsky.social A thread: [1/3]

Holoparasites are those plants that take water (+ minerals) AND sugars from their hosts. These plants lack both roots and chlorophyll, so they are wholly dependent on their hosts. This is the magnificent Lathraea clandestina. #parasite #Orobanchaceae #Botany 🌾🧪🌱

Orobanche cooperi is another holoparasitic Orobanchaceae from southwestern North America. Isn’t it fantastic? A bad-ass beauty! #parasite #Orobanchaceae #Botany 🌾🧪🌱

Ran into these AMAZING Stapelia grandiflora in our conservatory today. The patterns, colors, hairs, and the smell - carrion mimic to perfection. #Stapelia #plantjoy #iamabotanist

Imperial Morning Glory (Ipomoea purpurea) This is blue. I painted on hydrochloric acid to draw a smiley to showcase the color change due to acid directly on the petals.

I am pretty sure most people who follow my posts more or less know what bristlecone pine trees look like. There are so many iconic images from high elevation. But at low elevation in the Rockies their form can get crazy. Here is a pic from one site I sampled a while back when I lived in Utah.

Only known from a single plant growing in the botanic gardens in Sri Lanka, the endemic Pini-Beraliya was declared Extinct in the Wild. But a post on social media about the tree has now led to the discovery of three wild populations and a recovery programme! 🌱🧪🙌🏻 news.mongabay.com/2025/08/soci...

This approximately 15m-long fossil tree trunk from the Angeac-Charente bonebed of Early Cretaceous France is insane. #paleontology #paleobotany #botany

Prepping for the start of this year's teaching this #FossilFriday, starting with a story about Ginkgo leaves which fell in an Autumn 160 million years ago, and how the microscopic details of those fossil leaves can tell us about climate change. ⚒🌏🌱🧪🔬🌲💚

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
