Paleo Week: Research Biases Affect the Bryophyte Fossil Record www.botany.one/research-bia... Country level economic development and the number of grant-funded bryophyte researchers are major factors affecting fossil discovery #Botany #PlantScience

A beautiful set of branches of Archaeopteris, one of the first globally distributed trees, it's ideal for #FossilFriday!

For absolutely no specific reason, here's a photo of the Jurassic fossil #forest at Curio Bay, New Zealand, for this week's #FossilFriday 🌲⛏️🦕 (More about Curio Bay: en.wikipedia.org/wiki/Curio_Bay) #paleobotany

🌲 The Devonian was a transformative chapter in Earth's history. Forests rose. Resin evolved. Terrestrial ecosystems flourished. Plants drove many of the innovations that reshaped life on land：https://www.science.org/doi/10.1126/sciadv.aeh1266

Antarctica has only two species of flowering plants: Antarctic hairgrass (Deschampsia antarctica) Antarctic pearlwort (Colobanthus quitensis) Both are considered extremophiles because of their ability to survive/grow in the low-moisture, frigid temps of the icy continent. Let's talk about them.

I'm happy to have been one of the consultants for #SurvivingEarth E5 "When the forests collapsed" 🌿⛏️ "Showing" plants only known from ~300 million year old fragmentary fossils while trying to stay as scientifically accurate as possible IS frustrating, but I think the result looks good #paleobotany

Huge thanks to Mario @lepidodendron.bsky.social and Dieter Uhl at @sgn.one for letting @thibault-durieux.bsky.social and me rummage through the Senckenberg Devonian collections the last three days. Saw some wild fossil xylem in there among incredible pieces like these slabs of Trimerophyton.

New paper on uppermost Cretaceous fossil woods (and some leafy shoots) from northern Patagonia. Yes, it includes _Podocarpoxylon mazzonii_, the multiseriate rays-bearing and somewhat spatially and temporally restricted species. authors.elsevier.com/a/1nOm43BkFS...

Thanks to everyone who sent an abstract for the EPPC early career symposium! It's going to be ✅ record-breaking long ✅ with an amazing lineup We're still working on some details but you'll get an email from us in July with information re: schedule and panel for the prizes. #paleobotany #palynology

Ivy wraps an oak tree in a warm embrace at Uragh ancient rainforest. Remember: ivy is NOT 'parasitic', and doesn't 'kill trees', but is an important part of European woodland ecosystems, providing vital food, shelter and hiding places to a great range of animals. So please, just leave ivy be!

Nobody: what is a tree, anyway? Us:  authors.elsevier.com/sd/article/S... (Review out today, in which we ask whether xylem disconnection arising early in wood anatomy is convergent with disconnection seen across tall plants and whether tree evolution requires disconnection given periodic drought.)

#FossilFriday, petrified wood edition. ⚒️🧪🌴 You teach paleontology in coal country, your collection ends up holding an awful lot of dead wood. Silicified lycopods, Calamites compression fossils, carbonized fronds arm-wavingly assigned to Neuropteris ... and a lot of coal.
