Every state in the US contains fossils from ancient seas. The Smithsonian exhibit "From These Lands" highlights a few of them, an invitation to consider our connections to prehistoric waters. My latest for @smithsonianmag.bsky.social 🧪

The Sam Noble Museum is hiring a Collection Manager for the Fish Collection! Come work with me in Oklahoma! Please share widely! #TeamFish #MuseumJobs jobs.ou.edu/jobs/curator...

New paper out in JSP! Skeletal morphology and phylogenetics relationships of the Late Cretaceous freshwater ray Myledaphus bipartitus (Chondrichthyes; Batomorphii) by Türtscher 𝙚𝙩 𝙖𝙡., clarifying the evolutionary relationships of batomorph lineages: buff.ly/gDhmnXZ #PaleoSky #FossilFriday

Michigan plant lovers rejoice! The Michigan Flora app has been released! news.umich.edu/new-plant-id...

Happy #JMIH26! 🥳 Excited to be in New Orleans presenting some of my dissertation work! Stop by Grand Chenier tomorrow at 3:45pm to learn about the impacts of intermittent damming on steelhead cranial morphology 🐟

Away from Ann Arbor, so no UMMP collections for me. So here are some lovely Early Devonian echinoderms from the Hunsrück Slate of western Germany on display at PRI's Museum of the Earth.

Impressive new systematic treatment of fossil and living clupeomoeph fishes by Marramà and Carnevale: sciencepress.mnhn.fr/en/periodiqu...

Nice view, a few time zones east.

We will have a 23 month research associate role opening to support our work on mammal fossils from the Isle of Skye. Open to candidates with substantial CT-segmentation experience with Masters or PhD qualifications. Advert should be out next week - will post soon but do get in touch if of interest.

🧵 1/11New paper alert! One of two out today from #NearLab Ever heard of the Holiday Darter? These beautiful freshwater fish are hiding a big biodiversity secret in the rivers of Georgia, Alabama, & Tennessee and new genomic data is revealing it. A thread 👇

On the road, but a quick spin through a trio of recent papers with implications for acanthomorph evolution. First off, Allison Murray and colleagues describe two new spiny-rayed fishes from the freshwater late Cretaceous "Pisces Point" site in Alberta: cdnsciencepub.com/doi/10.1139/...

Hari Sridhar hs a nice bew paper on the role of natural history in ecology and evolution www.journals.uchicago.edu/doi/10.1086/...

NAPC 2028 website is now live! napc2028.sites.utk.edu

Similar vibe further east, but with more topography and older rocks. Genesee Group in Treman State Park near Ithaca, NY. Learned undergrad geology on stuff like this.

The Silurian jawless fish Americaspis americana (UMMP VP 120281) for the 4th.

Coming to you live this #FossilFriday from the Cleveland Member of the Ohio Shale Formation.

No UMMP collections today, but I did see this Egyptian relief of a couple of speared Nile tilapia from ~650 BCE.

Traveling tomorrow, so will miss my usual collections day. So here's one from the vaults: a large tooth of the brontothere Megacerops.

Nothing to see here, just a cart of skulls.

Love the random things that you find in museum storerooms, like this model of a rookery.

We are pleased to announce that the Dept of Earth & Environmental Geosciences @colgate.edu is hiring a tenure-stream asst professor in paleoclimate! For additional info regarding the position & to apply: apply.interfolio.com/188708 . Please share broadly & contact us with your questions. Thank you!

Two new 🐟 preprints! First with @cmartinez.bsky.social on diversification in a wonderfully wacky group of deep-sea fishes www.biorxiv.org/content/10.6...

Swimming into #FossilFriday

Y'all - the Smithsonian is hiring three new curators - herpetology, ichthyology, and ornithology! Notably, this is a 2nd fish curator position - i.e., not the same as the one advertised last month. So if you applied for that one apply again. www.usajobs.gov/job/873849000

Really excited to share that Chris Martinez & my paper on ecological, functional, & evolutionary diversity produced by novel jaw joints in fishes is out [email protected]! We show how modulation of these new joints can produce a wide range of functional opportunities doi.org/10.1093/evol...

Happy to share our new paper in Nat. Comm. on the evolution of planktivory in surgeonfishes and relatives 🐠🧬 Combining fossils and genomics, we find multiple independent origins of planktivory, plus convergent positive selection in key genes linked to planktivory. 👉 www.nature.com/articles/s41...

Cleveland Museum of Natural History was incredible!

🦀 see a crab, post a crab 🦀 Thursday is collections day, so enjoy this three-dimensionally preserved specimen of Avitelmessus grapsoideus from the Upper Cretaceous of Tennessee (UMMP IP 33406). Paper here: deepblue.lib.umich.edu/items/528e26...

Holy mola! Beautiful articulated Masturus from the Miocene of Korea: www.tandfonline.com/doi/full/10....

New overview of snakehead relationships based on morphology of fossil and modern species: journals.library.ualberta.ca/vamp/index.p...

New preprint on Eupercarian fishes is here! We present a new phylogeny and skull shape analysis of this massive clade! www.biorxiv.org/content/10.6...

I’m recruiting a PhD student to join our lab in the fall of 2027. If you’re excited about phylogenetics, comp bio, paleobiology, stats theory, macroevolution, etc. please get in touch! Folks at #Evol2026, you can talk to @brpetrucci.bsky.social & @sigournie.bsky.social to learn more about our lab

Inspired choice for this year's summer camp shirts at UMMNH.

Go work with Jake--he's fantastic!

Otoliths provide an important new snapshot of Philippine marine fish diversity in the Pliocene: riviste.unimi.it/index.php/RI...

Just a reminder that I'm recruiting PhD students to my new lab! Come find me at #Evol2026 to chat! #TeamFish

New paper out today! @sternarchella.bsky.social and I review how modularity and integration influence adaptive radiations and diversification. Read it here: rdcu.be/fpcSX

New material of Enchodus petrosus from Late Cretaceous Bearpaw Fm (Alberta) sheds light on this widespread predatory fish. Four well-preserved skulls reveal novel braincase anatomy, premaxillary fang fossa, & sympatry w/E. gladiolus. Nelson et al anatomypubs.onlinelibrary.wiley.com/doi/10.1002/...

Results from the Flocking #paleostream! Palaeoloxodon, Palaeosaniwa, Rhomaleosaurus and Utaurora

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/...

Another beautiful 3D coelacanth, Aemilia, this one from the Carboniferous of USA, published today by Jorge and colleagues. Great work! sciencepress.mnhn.fr/en/periodiqu...

🧠 At long last... our paper "Ethmosphenoid #endocasts elucidate evolutionary #brain divergences and interrelationships of stem tetrapods (Sarcopterygii, #Tetrapodomorpha)" has been published, today in Papers in Palaentology @thepalass.bsky.social - onlinelibrary.wiley.com/doi/10.1002/...

Interesting dive into endocast anatomy in some of the closest 'fish' relatives of land vertebrates. Congrats to @draliceclement.bsky.social & team.

Back from the field on this #FossilFriday to see the humbling news that a gorgeous little Carboniferous fish bears a new name: Unionichthys friedmani. Thanks to Struan Henderson and @gilespalaeo.bsky.social for this honor. www.tandfonline.com/doi/full/10....

Nice view.

I'm a real paleontologist now 😅
