Global warming 56 million years ago
Lower latitude "shift to smaller plants such as palms and ferns. Leaf mass per area also increased as deciduous trees declined. Fossil soils indicate reduced soil organic carbon levels" ⚒️🧪

56 million years ago, the Earth suddenly heated up – and many plants stopped working properly
It could be a sign of what’s to come.

As botanists and Plant Architects in Montpellier 🌿, his vision of forests 🌳 profoundly shaped the way we think about and observe plants. A giant has passed, but his legacy will remain a major source of inspiration, worthy of our deepest admiration and gratitude.

Um tronco petrificado da Era Paleozoica (Período Permiano) em Altos, PI. Quando o primeiro dinossauro caminhou na Terra, este tronco já era um fóssil.

Prosopanache is the tropical American answer to Hydnora of Africa. The two genera are sisters, holoparasitic & lack chlorophyll. They appear above ground only as flowers. This is Prosopanche americana, parasitic on legumes. 📷: Agustín Zarco CCBY4 #Aristolochiaceae #Botany 🌾🧪🌱

I'm resharing in English the very sad news of the passing of French botanist Francis Hallé, specialist of tropical #forests and #tree architecture. You can find more about his life and career (and see some of his amazing drawings) here: www.foretprimaire-francishalle.org/en/who-is-fr...

We probably don't often plan to snack on tree bark, but we certainly do. Cinnamon is tree bark. There are five species of cinnamon from different geographical locations with distinctly different flavor profiles. This one is Cinnamomum verum, Sri Lankan cinnamon. Eat some bark today!

A sprinkling of leaves dropped from the host tree and gently landed on the wet ground below it. 260 million years later they find themselves encased in a block of stone in my study

Glossopteris were the dominant trees of the Permian Period

Pour Noël, je me suis offert un objectif macro pour smartphone. Plus de botanique en 2026, voilà ma résolution de nouvel an. Qu'est-ce que vous en pensez ? Saurez-vous deviner de quoi il s'agit ? 
Bonnes fêtes à toutes et tous !

I am interested in working with an artist on a graphic novel on soil and/ or global environmental change. The lab would have money to fund this.

Do you know of any graphic artists that would be interested?

Here are some of the subfossil wood samples that have been shipped all over Europe these days as counterparts for my recent crowdfunding campaign on Wemakeit! 🧊🔬

Thank you to all contributors for this incredible success! 🙏

A doubly old 'Christmas tree' this #FossilFriday! This was taken on Dec. 23 2010 during my 1st trip to Antarctica & shows a large fossil tree from the Triassic, 240 million years ago. The locality is high in the Transantarctic Mountains, above the Antarctic icesheet 🌿⛏️🏔️ Happy holidays!

A year ago, Nora and Aly recorded an “Episode 0” to get a feel for the process and decide if they really wanted to make a podcast.

Some plants are famously active in the winter. So famous, in fact, that they have become immediately recognizable symbols of Christmas and Winter Solstice holidays.
