last week my latest paper on #cycads came out.
The article deals with the idea of cycads as "living #fossils", but what does this mean exactly, and what did we actually test? A thread for #FossilFriday!

Disparity of cycad leaves dispels the living fossil metaphor - Communications Biology
An analysis of leaf disparity through time in cycads shows that this group has a dynamic and expanding morphological diversity until the present, and thus does not fit the ‘living fossil’ hypothesis o...

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

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

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

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 🌾🧪🌱

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.

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.

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?
oh yeah, great I wondered if any of the heroes from NZ would also get tagged this way
