Alt: Photo with POV looking down on the shoots of this plant with opposite leaves. Each leaf is three-lobed, and each lobe ends in a spine tip.

Many leaves (or parts of leaves, such as the leaf tip or leaf margin) are modified into sharp defensive armaments. Modified leaves or leaf parts are spines. This Osmanthus heterophyllus 'Sasaba' has wonderfully spiny foliage. 📷: Arb O'Retum CCBYNCSA2. #Oleaceae #spine #Botany 🌾🧪🌱

Continuing my exploration of Jurassic paleobotany, this time with ferns of the family Dipteridaceae. Fossil taxa like Clathropteris have a really interesting shape that for me is pretty difficult to get right.

Last week, I attended the EMBO workshop in Vienna on early land plants and terrestrialisation.
There, I presented my research on rhacophytalean evolution, focusing on a reappraisal of the genus Cephalopteris from the latest Famennian of Bjørnøya. 🌿🌿

The frequency and importance of polyploidy in tropical rainforest tree radiations The presence of two or more copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. The Amazonian tr...

More paleobotanical studies - this time the Mesozoic dipteridacean fern Hausmannia. Another example of how ferns during this time exhibited a diversity of forms that can spice up #paleoart

Matonia pectinata is a beautifully-shaped fern, and the family it belongs to can be traced back to the Late Triassic. When researching I often make reference sheets like this of the most useful figures, photos & illustrations I can find. Most pics from iNaturalist or Flickr. #paleobotany #botany

A 125 Ma old log provides a seat. Compton Bay #Isleofwight. Probably Pseudofrenelopsis, an extinct genus of conifer. #FossilFriday

A PowerPoint title slide with the words The Problem with Plants, Why restoring extinct plants is difficult for palaeoartists.

So, an unexpected development, but I'm gonna be giving a talk tomorrow at SVP in Birmingham!!!!! I'll be speaking about palaeobotany in palaeoart, so hopefully it goes well despite being slightly rushed😅.

Anyway, if you're gonna be around for #SVP tomorrow, come say Hi!!! #paleoart #palaeobotany

A close up of the canopy of a plant with several thin stems ending on clusters of long serrated interlocking leaves.

I haven't posted much in a while because, probably unsurprisingly, my PhD has kept me busy! But I was just using this drawing of Wielandiella angustifolia from last year, and I realised that I've never shared a close-up showing all the details of the leaves! So anyway, enjoy! #paleobotany #paleoart

Photo with POV looking down onto a shoot that has spirally arranged branches that look like pinnately compound leaves. Smaller, emerging branches look like emerging, expanding leaves.

Phyllanthus has what is called “phyllanthoid branching”: Orthotropic (erect) shoots with spirally arranged leaves & plagiotropic (horizontal) branches with distichous leaves. Guam’s P. saffordii shows the dimorphism. 📷: Lauren Gutierrez CCBYND2. #Phyllanthaceae #TropicalBotany #Botany 🌾🧪🌱

These ancient bumblebees were found with their pollen source Insects have long pollinated plants, but evidence of ancient pairing is rare. Fossils now show bees and linden trees goes back 24 million years.

Scientists just found several fossil bumblebees covered in pollen that directly matches fossil flowers nearby.

The 24-million-year-old discovery reveals the oldest known evidence connecting pollinators to the pollinated.

New at @sciencenews.bsky.social

a flow-chart with 2 islands. "Do I need AI?" that flows into a final island saying "No"

so both the stories labelling the Sumud flotilla as "Hamas" have been removed from the topic now (as far as I can see)

That still leaves some serious questions about how and why these stories were tagged - what's the process here, and more importantly *why* has it tagged these specific stories?
