My Scandinavian research saga continued this week with a visit to the collections at the Naturhistoriska riksmuseet in Stockholm. I was here for the Palaeogene carnivores from Quercy, France, but also very much appreciated the monumental architecture and Linnaeus paraphernalia!

After a month catching my breath in the UK, the second round of my sabbatical research tour is underway in Copenhagen 🇩🇰! Thanks so much to the staff of the @nhmdk.bsky.social for being so welcoming during my quick trip to look at some of their Cenozoic mammal fossils.

I’m in Poland 🇵🇱 for research this week and it’s simultaneously #MuseumMonday, #MammalMonday, and #MegafaunaMonday. In honor of all that, I wanted to share the fantastic Ice Age exhibits at each of Warsaw’s lovely geology museums, starting with the brand-new display in the Muzeum Ziemi.

This #FossilFriday is a two-fer! The double-horned Eocene mammal Arsinoitherium (seen here in the @nhm-london.bsky.social ) is the 2nd in my series of salutes to the Egyptian fossil record in honor of #TeamEgypt making the @gonzagauniversity.bsky.social campus their home during the World Cup.

I’m in Seattle this #FossilFriday, where I’m always happy to see how the modern plants in the @burkemuseum.bsky.social garden are growing in around the slab of Chuckanut Formation palm fossils, relics and evidence of a much warmer climate in the Eocene of western Washington.

I don’t normally do selfies, but when the passing of the @gonzagauniversity.bsky.social grade deadline and the beginning of your sabbatical coincide with a ferry trip through the Gulf Islands, it feels like a moment worth commemorating.

Today we had the chance to celebrate all the Biology majors about to graduate from @gonzagauniversity.bsky.social, including lab members Ella and Kevin. I'm proud of the great work they did over their four years here and am excited to see what's next for them!

Spring has sprung in the Great Northwest this #FossilFriday! With leaves starting to bud it's worth reflecting on our region's incredible plant fossil record and the story it tells of deep time environmental change (Photos from the Field Museum, John Day Fossil Beds, and @burkemuseum.bsky.social).

Happy #WorldBearDay! Alongside our 6 living bear species, ursids are also extremely well-represented in the fossil record. The most famous is the massive Ursus spelaeus, or cave bear (Höhlenbär in German, seen here in skeletal from at @sgn.one and in dioramic glory in Basel), of Ice Age Europe.

Happy St. Patrick's Day from the MEAT Lab! For centuries, the Irish have been finding gigantic deer skulls preserved in peat bogs across Éire. So common and well-preserved were they that some were displayed in Medieval halls like trophies, such as the skull in the rafters of Cahir Castle. (1/3)

Last year, lab member Peyton was awarded a student research grant by @geosociety.bsky.social for her research on the paleoenvironments of Miocene marine mammals from the Oregon Coast. This #FossilFriday, we're excited to see her work featured in the most recent issue of GSA Today (on Page 15)!

It's #FossilFriday & @ipc7.bsky.social registration & abstract submissions are open! I'll be there co-chairing a session on afrotheres & talking about the ecology of an out-of-place sea cow from Oregon. I hope you can join us to share your work on elephants, aardvarks, sengis, tenrecs, hyraxes, etc.

The Afrotheria: Origins & Evolution of Africa’s Iconic Mammals
Despite comprising fewer than 100 extant species, few mammalian lineages contain as high a degree of morphological and ecological disparity as do Afrotheria. So great is the disparity between extant
aardvarks, sengis, golden moles, tenrecs, otter shrews, hyraxes, sirenians, and elephants that they were not recognized as a monophyletic clade until the advent of molecular phylogenetics less than 30 years ago. The rich afrotherian fossil record includes not only members of extant families, but stem taxa and extinct orders
such as embrithopods. This incredible diversity has inspired a corresponding variety of palaeontological and evolutionary questions. This symposium will showcase the diversity of research and researchers
working on Afrotherians in areas that may include, but are not limited to the origin of the group, phylogenetics, systematics, major transitions, functional morphology, biomechanics, palaeoecology,
biogeography, biostratigraphy, ichnology, and conservation palaeobiology.

Chúc mừng năm mới 새해복많이받으세요 恭喜发财 Whichever language you say it in, happy lunar new year! Equids loom large in the study of paleontology and evolution, so we in the MEAT Lab are excited to celebrate the Year of the Horse! (See picture alt text for details and photo credits).

Miohippus was one of the first genera to move out of the forests and onto the savannas of Oligocene North America (mural from John Day Fossil Beds National Monument, Oregon, painted by Roger Witter).

While not nearly as diverse as they used to be, equids are very much still with us today, not only in the form of domestic horses and donkeys, but as wild horses, asses, and zebras on the plains of Asia and Africa (photo from South Luangwa National Park, Zambia).

Eurohippus from the Eocene Messel lagerstätte was, like most early horses, a small forest-dweller that lived alongside closely related hoofed mammals that would give rise to rhinos and tapirs (photo from the Senckenberg Museum, Frankfurt, Germany).

Over the last 25 million years, horses have been part of an evolutionary dance with grasslands, which shaped and were shaped by increasingly large, fast, and grass-eating equids like Merychippus (back right), Equus simplicidens (Idaho's Hagerman horse, middle), and Equus occidentalis (front left; photo from Carnegie Museum of Natural History, Pittsburgh, Pennsylvania).

#SICB2026 is a wrap! Thanks to @sicb.bsky.social for hosting a great conference (as always), to all the speakers and workshop organizers for sharing your inspiring work to move biology forward, and especially to everyone who came by our poster and gave my student excellent feedback!

Took the scenic route to #sicb2026 today. If you’re in Portland too, come say hi, and make sure to catch my student’s poster on Tuesday to learn about our work on desmostylian shoulders!

So excited to be a part of this symposium at next year’s @ipc7.bsky.social! If you work on elephants, sea cows, aardvarks, tenrecs, hyraxes, or any of their relatives, I hope you can join us in Cape Town!

Our undergrad researchers have been doing some great work in the field, museum, and lab on the paleoenvironments of Oligocene marine mammals from the Northwest Coast. And now it's confirmed that they'll be presenting that work at the @geosociety.bsky.social meeting in October!

As of this #FossilFriday, I'm officially hosting a symposium on Afrotheria at next year's IPC in Cape Town! There's still a lot to work out, but if you work on elephants, sea cows, aardvarks or any of their relatives (and can make it to South Africa) please consider being a part of this session!

One of the perks of doing research at John Day Fossil Beds National Monument is getting to stroll through the exhibits afterwards. Besides telling a great story about climate change and evolution, they are a textbook example of how great paleoart can elevate a paleontology display.

The lab is working on describing some carnivores from Oregon's John Day Fossil Beds National Monument, so I had an excuse to run down to one of our planet's more dramatic fossiliferous landscapes (and my old stomping grounds) over our Spring Break.

Hello from the Morphology & Ecology Across Time Lab at @gonzagauniversity.bsky.social! We use the fossil record to explore the evolution of mammals and the forces that drive it. Follow us for research updates, news, and fossil photos (like this one of the rhino Teleoceras in the Carnegie Museum)!
