Our latest, led by the inimitable Chris Kay "Dated gene duplications elucidate the evolutionary assembly of eukaryotes" in which we used gene duplications to test hypotheses of eukaryogenesis. TLDR? They're all wrong. With @tweethinking.bsky.social @anya1.bsky.social @ssolo.bsky.social Davide Pisani

Today on #givingtuesday I'm continuing to support the Paleontological Research Institution. As a former employee and current board member, I know how incredible this place is - a resource for anyone who cares about our earth's past and its future: priweb.donorsupport.co/page/FUNWALK...

*Gain skills and training in journal publishing!* Open Palaeontology is looking for Managing Editors and Steering Committee members! Please consider helping to shape community open-access publishing in palaeontology, and spread the word! openpalaeo.org @openpalaeo.bsky.social

It was really great to hear everyone's exciting new research at GSA! ✨ I had a great time sharing a bit about what I've been thinking most about recently at work: old tiny fossils from the Grand Canyon, carbonate petrology, and early eukaryotic ecology!

New in Trends in Ecology & Evolution: 'Earth system engineers' and the cumulative impact of organisms in deep time 🔓 #ecoevo #openaccess www.sciencedirect.com/science/arti... A thread 🧵:

New paper led by my PhD student, Edwin Rodriguez! Building on previous work, we present a systematic description of the ONE BILLION YEAR OLD fossils of the phosphates of the Diabaig Formation, NW Scotland — including some early eukaryotes and new species... #paleontology #fossils #geology

Paleo Society will host 6 events over the 4 days at GSA in San Antonio, TX, so mark your calendar! 📆 Be sure to stop by the PS booth to pick up some swag and meet some of our wonderful members and student ambassadors! #Paleontology #GSA #PaleoSociety #GeologicalSocietyOfAmerica #GSAConnects2025

Howdy Paleo pals! Reminder that registration for GSA Connects 2025 is now open! Keep an eye out! 👀 Over the next few weeks we will be featuring Paleo Society endorsed sessions at GSA Connects 2025. #gsaconnects2025

New #RSOS paper: Sustained shift in the morphology of organic-walled #microfossils over the Ediacaran–Cambrian transition. Read more: royalsocietypublishing.org/doi/10.1098/... #palaeontology @kellyetingle.bsky.social‬ @rosspanderson.bsky.social @kelleypaleolab.bsky.social

Science has published a letter I helped write, as part of Advancing Queer & Trans Equity in Science (AQTES), about why it's important for universities & other institutions to protect trans and gender-nonconforming scientists, and some practical things they can do. www.science.org/doi/10.1126/...

✨ Excited to share our new paper! ✨ Sustained shift in the morphology of organic-walled microfossils over the Ediacaran–Cambrian transition doi.org/10.1098/rsos... @royalsocietypublishing.org @rosspanderson.bsky.social @kelleypaleolab.bsky.social

‪[1/n] New paper co-lead by @emmadnn.bsky.social‬ @macroecoevoale.bsky.social‬ and I: we combined fossil occurrences, biogeography and climate modelling to investigate the origins and early evolution of pterosaurs 🔗 www.nature.com/articles/s41...

🧪 New paper led by @noracc.bsky.social! We measured redox around decaying organisms. Turns out, the bigger and richer in protein you are, the more easily reducing conditions form around you after death, making you more likely to get mineralized and become a fossil (?). www.nature.com/articles/s41...

Last day of the IRATE workshop in Erlangen. See the happy faces! Looks like everybody had a good time and hopefully fruitful discussions... can't wait to see the outcomes published ^^ (no pressure at all ;))

#WeekendReading: Faulkner et al. (w/ @rowanmartindale.bsky.social; @chrislowery.bsky.social) on how the test walls of foraminifera change through the Phanerozoic and what might that have to do with ocean chemistry. 🧪⚒️🌊 royalsocietypublishing.org/doi/10.1098/...

A fantastic and productive week creating new resources for the next generation of experimental taphonomists! Thanks to @orlabe.bsky.social for driving this forward with me and @paleosynth.bsky.social for hosting us!

Consider applying for Paleo Society Student Rep! Applications close in a few days!

Algae and friends in their busy, tiny world! 🔬 these videos are from experiments I was running which grew algae in a variety of different settings to get a better understanding of how algae can trap and grow minerals. 🌱💎

Applications for the Paleontological Society Student Rep are open! ✨ It's a great opportunity to help student members by fostering community, creating opportunities, and ensuring student voices are heard. Apply here by March 15: docs.google.com/forms/d/e/1F...

Hello 👋We are Open Palaeontology, or OPal, a brand new Diamond Open Access journal for palaeontology research. Our mission is to provide a flexible platform for research that is free to authors and readers. Read more in our editorial www.openpalaeo.org/article/view... or at www.openpalaeo.org!

One more month! Apply for a place at the Analytical Paleobiology Summer School. Financial support is possible: www.paleosynthesis.nat.fau.de/index.php/sc...

Check out the official logo for Mid-Atlantic #Geobiology 2025! Featuring North America’s largest estuary—the Chesapeake Bay!

🚨 Nora's second PhD paper is out! I can't be prouder! We experimentally demonstrate that marine shrimps can be rapidly replicated by clay minerals after death, even without burial, thereby increasing the likelihood of arthropod fossilization over geological time. 🦐 🧪 www.nature.com/articles/s43...

Love this geologic timescale mural at Missou Geological Sciences!

🌟 Exciting news! OPal is live—a new Diamond Open Access journal for palaeontology! 🦐 We welcome traditional formats, hypotheticals, preregistered protocols & multimedia articles. 🦖Together we build a platform for impactful and responsible research! 👀 Visit: www.openpalaeo.org/article/view...

Add another exciting #LifeAndPlanet meeting to your calendars!
