Another paleo position open: Professor of Practice and Curator in Charge, Vertebrate Paleontology Laboratory at UT Austin apply.interfolio.com/175702

Position right next door for vert paleo! jobs.rutgers.edu/postings/260...

Folks, I am always happy to send papers through research gate...but maybe you wanna avoid the trouble when the papers are open access...just saying

Our latest paper, now how to conciliate apparently discrepant evolutionary rate patterns in squamates, but which may well apply to any study system with Stephanie Pierce and @7brumas.bsky.social #macroevolution academic.oup.com/sysbio/advan...

Today was a hard day for Ph.D. students who found out that they can no longer apply for NSF's prestigious Graduate Research Fellowship Program. "Devastating“ was how one student described it to me. #GradSchool #NSFGRFP www.science.org/content/arti...

Tenure-track Assistant Professor position in Bioinformatics in the Department of Biology at the University of San Francisco usfca.wd5.myworkdayjobs.com/en-US/USF_Fu...

Really nice paper! Taphonomic megabiases constrain phylogenetic information in the squamate fossil record www.cambridge.org/core/journal...

Happy to share the advance version of our big AREES review on squamate origin and early evolution: From Fossils to Genomes with my two amazing colleagues, Frank Burbrink and @marcanthonytollis.bsky.social www.annualreviews.org/content/jour...

Important updates on EvoPhylo (release 0.3.5)! cloud.r-project.org/web/packages... Nothing like a sleepless night to fix some bugs and add new features. Website with updated articles too: tiago-simoes.github.io/EvoPhylo/

Michigan State University is hiring a new Director of our herbarium! This is an open rank, tenure-stream faculty position, with research focus in plant or fungal systematics, ecology, and/or evolution Please consider applying and help spread the word! plantbiology.natsci.msu.edu/job-postings...

Gracias Barcelona y #eseb25 por la semana increible con debates científicos y nuevos colegas!

If you like evolutionary rates or donut-shaped trees, check out the poster bybstudent Ruby Redlich (313) today at #ESEB25 benchmarking rate inference performance

New BEAST!

Adaptive landscapes unveil the complex evolutionary path from sprawling to upright forelimb function and posture in mammals dx.plos.org/10.1371/jour...

That's a feels like of 108 for the Fareheint minded! And 82 at work even with AC at 65! I thought I left that behind when I left Rio

If universities anywhere are hiring an Evolutionary Biologist/Paleontologist please let me know! I'm on the market for Tenure Track positions!! You can find more about my research on fish evolution here: rtfigueroa.wixsite.com/my-site

Our latest Paleo paper: a neotype for Calanguban alamoi (Cretaceous lizard from the Crato Fm in Brazil) The holotype had been destroyed by fire in the National Museum of Brazil in 2018. Glad to have this species name back as a true taxonomic phoenix! www.tandfonline.com/doi/full/10....

🚨Palaeoverse Lecture Series🚨 It’s time to announce our Summer 2025 talk schedule 👀 Looking forward to hearing from @spissatella.bsky.social, @sauropodlets.bsky.social, @nmkphylo.bsky.social and @russellgarwood.co.uk! Sign up here: bit.ly/palaeoverse-lecture-series-2025

Millions of birds nest in the Arctic each year. But did you know they’ve been doing this since the Cretaceous? Can’t believe I finally get to share that our paper on the birds of the Prince Creek Formation is out in ‪@science.org (and on the cover)! 🧵 Art: Gabriel Ugueto ‪@serpenillus.bsky.social

Excited for the first day of virtual #evol2025? The workshop day is always important for our community, especially early-career members. Think you might want to organize a workshop someday? Now is your chance - The SSB standalone is coming up in January! #ssb2026

🧵🧪 With ongoing reductions in the funding in the US (NSF, NIH, NASA) there are calls for countries like Canada 🇨🇦 to step in to absorb US researchers and their work. However, that requires a significant commitment in resources. Funding for graduate students in the natural sciences in Canada

Our new preprint on apparent evolutionary rate incongruences in squamates for discrete vs GMM data across distinct methods, and what these patterns may reflect of their underlying phenotypic evolutionary processes: ecoevorxiv.org/repository/v... #evolution #squamates

I am looking for a PhD candidate to work on the morphological and functional evolution of the head shape of limbless squamates. The project will involve evolutionary biology, experimental and computational biomechanics, and a lot of scaly animals!!! More info here: adum.fr/as/ed/voirpr...

📢 Tired of choosing between fossils to incorporate into your phylogenetic analysis? Us too. 💥 Check out our new preprint on incorporating stratigraphic ranges into the FBD model, implemented in BEAST2. We explore how using ranges affects the inference of dog 🐶 and penguin 🐧 trees 🌳

Nice review of the FBD model and its application using fossil data: www.cambridge.org/core/journal...

🚨New publication alert!🚨 A big one! It might just be my *biggest* one: doi.org/10.1093/iob/... IMPORTANT THREAD! From the moment Dave Blackburn set me loose at the Florida Museum, I had a marvelous time using diffusible iodine-based contrast-enhanced CT (diceCT) to create anatomical datasets 🧪1/6

We need to stop using plastic for packaging

Yep...not a dire wolf! Only a GMO gray wolf. #notmydirewolf

It's not a dire wolf. It's a gray wolf clone with 20 dire-wolf gene edits, and with some dire wolf traits. And here's my story! Gift link: www.nytimes.com/2025/04/07/s...
