Hydraulic function of medullary bundles in a tropical root climber New #AJB research by Sandrine Isnard, Damien Longepierre & Taylor Feild doi.org/10.1002/ajb2... #botany #plantscience #Melastomataceae @umramap.bsky.social

Some other tools exist, based on the variation of wood anatomy and/or of carbon isotopes within individual growth-rings of fossil trees. You can find an example in our open access paper from 2014, looking at Permian high latitude trees : www.lyellcollection.org/doi/full/10.... Happy #fossilFriday!

Another paper from our NASA-funded project on ferns has dropped! UWyoming MS student Fern (really!) Holian, developed a new schema for classifying fossil ferns, which are understudied. 🧪🌿☄️

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the.....

For #FossilFriday a video showing the use of photogrammetry for 3D reconstruction of fossiliferous outcrops. Here a Carboniferous rock with faint impressions of Calamites, an extinct relative of horsetails 🌿⛏️❄️💻 The objects are used to test for image distorsion. youtu.be/x91SQRGwK2k?... #paleobotany

Following in the footsteps of pioneers like Nathorst, Antevs, and Schweitzer, we are setting out to explore the Late Devonian strata of Bear Island. Our goal: to uncover its unique endemic fossil flora and fauna from over 360 million years ago. 🌿🦴 #Paleobotany #Devonian #Svalbard #Bjørnøya

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

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

A little attempt at a Triassic landscape in gouache. The two main trees are Voltzia heterophylla (L) and V. walchaeformis. Still researching these so forgive any inaccuracies! #palaeoart #palaeobotany #paleobotany
