Environmental phylogenetics supports a steady diversification of crown eukaryotes starting from the mid-Proterozoic | PNAS www.pnas.org/doi/10.1073/...

Super excited that our paper led by @sandinmm.eurosky.social in PNAS is out! We show that crown-group eukaryotes were already taxonomically and ecologically diverse throughout the Mesoproterozoic, revealing complex communities well before the Neoproterozoic radiation. www.pnas.org/doi/10.1073/...

Years ago I was able to visit a museum with this fantastic model of the Cambrian worm Ottoia! Interpreted to have been an early priapulid worm ("archaeopriapulid") ! They had a lovely model of it! #wormwednesday

(1/2) Resembling the tiny parts of an impossibly intricate and eye-catching timepiece, strewn from a watchmakers toolkit, these are in fact fossil Crinoids, Corals, Bryozoans and Brachiopods.

Tired of AI-generated figures? I asked our talented scientific illustrator Manon Zuurmond to draw some of the instruments and lab equipment we missed in NIH's otherwise fantastic BioArt resource.

What if flowering plants didn’t rise after the dinosaurs died out? New fossils suggest angiosperms were already thriving 10 million years earlier—challenging a long-held evolutionary narrative. #Paleontology #Fossils #Evolution

Tubulipora liliacea is one of the more common Tubulipora species in Norway. It forms beautiful, upright lobes with zooids in connate rows, and living colonies are often light purple/violet-colored! Photo: Maria Grankvist Buhaug #Bryozoa #NorDigBryo

Does the exception proves the rule? Or exception is just an exception? Maybe larger sizes of fruiting bodies had a spatial structure and "were waiting" for the right conditions in the future? The Cenozoic still shows permanent shift to larger fruit sizes. www.science.org/doi/epdf/10.... 🧪 #Geology

Dear bryozoologist friends, next month I’ll be presenting the work of Yolanda Herrera Anduaga, the first Mexican bryozoologist, at a major book fair. I’d love to highlight her mentors, including Dr. Simone Pouyet.

Yesterday with Liudas Daumantas and several PhD and MSc students we've had an expedition which was dedicated to the search and (re)discovery of the Givetian-Frasnian age vertebrate bearing deposits of the Oldredia (here is more about it's tectonics www.sciencedirect.com/science/arti... ).

The first tetrapods that moved onto land did not grow like today's amphibians. No larval stage, no metamorphosis, just little babies that grew directly into adults. As shown by fossils from Illinois!

New in @science.org ...since our first discoveries of early tetrapods, they have been thought of as "amphibians" characterized by aquatic larvae. But is this true? For the first time, we report exceptional fossils of stem tetrapod babies that upend this paradigm. 1/n www.science.org/doi/10.1126/...

#TrilobiteTuesday Ever wondered what the underside of a trilobite looked like? The answer can be found in this model trilobite I stumbled across languishing on a desk in the NHM last week.
