"Pithecanthropus Erectus" by Charles Mingus YouTube video by MegaAlexandroid

Join me in celebrating the first #FossilFriday of #JazzAppreciationMonth with this masterpiece of paleo-themed post-bop by the great Charles Mingus.

A display from the Field Museum showing plant fossils from Oregon and Washington that appear more similar to those of modern Appalachia than the Northwest.

A mural by Larry Felder showing the John Day Basin in the Eocene Epoch, featuring a thick liana (vine) in front of a lake reflecting dense, tropical rainforest-like vegetation.

A mural by Larry Felder showing the John Day Basin at the boundary of the Eocene and Oligocene Epochs, featuring vegetation in fall color and appearing similar to what you might encounter today in the Appalachians or parts of China.

A display at Seattle's Burke Museum that uses plant fossils from around the Northwest to track changing climate during the Eocene, Oligocene, and Miocene Epochs.

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).

A head-on view of the impressively robust skull of a cave bear in Frankfurt's Senckenberg Museum.

A diorama of a cave bare in the Natuurhistorisches Museum Basel, showing a bear in front of a cave mouth with Swiss scenery in the background.

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.

A couple of notes: my understanding is that the modern Irish name for Megaloceros would be fia mór, but any Irish speakers should correct me!
If you're interested in the Westropp study I mentioned, it's freely available from @clarelibraries.bsky.social and is a folkloric and linguistic gold mine!

Two Irish giant deer skeletons in the atrium of the opulent Museum Building of Trinity College.

T.J. Westropp (an alumnus of @tcddublin.bsky.social, home of these skeletons) found that the peat diggers of County Clare uncovered Megaloceros skulls so often that they had a Gaelic name for them: fiadh mór. Meaning 'great deer,' it's the best name I've heard for these magnificent animals! (3/3)

Three huge skeletons of Irish giant deer (two antlered bucks and one doe), with even more Megaloceros skulls on the wall in the background.

This deer, Megaloceros giganteus, has become an Ice Age icon. It ranged across Eurasia, but remains best known from Éire, as attested to by these fossils in the @nmireland.bsky.social, hence its poetic, evocative, and, sadly, geographically and taxonomically imprecise common name 'Irish elk.' (2/3)

The huge skull of an Irish giant deer in the rafters of Cahir Castle

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)!

I neglected to mention that I will be co-chairing this session with @tegnikus.bsky.social. Please reach out to either or both of us if you have any questions or would like more information.

The monolith of Sheep Rock, the most dramatic outcrop of Oregon's John Day Formation, whose rocks and fossils may have a lot to say about the timing of amphicyonid ("bear-dog") migration between Eurasia and North America.

Skeleton (and fossilized trackway) of the giant "bear-dog" Amphicyon, a genus whose range encompassed both Europe and North America (seen here in the Raymond Alf Museum, Claremont, California).

While I'm promoting conferences this #FossilFriday, the @eavpalaeo.bsky.social early registration window is closing soon. It'll my first EAVP and I'd love to see as many of my 🇪🇺 colleagues as possible in 🇱🇹 to share my work on the migration of giant amphicyonids between Europe and North America.

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.

The Nye Formation near Newport, Oregon, unexpected site of a warm-water sea cow in the cold North Pacific.

An extinct Steller's sea cow (a not-too-distant relative of the Oregon sirenian) and an African manatee (a much more distant relation) in the skeletal menagerie of the Muséum national d'histoire naturelle, Paris).

West Indian manatees, the most familiar living sirenians to those of us in North America, Crystal River, Florida.

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 Paleontological Society statement on recent events.

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).

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!

#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!

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!

The John Day River flowing past the monolith of Sheep Rock

The monumental wall of badlands at Foree

The green and red badlands of the John Day Formation

The Clarno Palisades, towers formed by erosion of Eocene volcanic mudflows

The scenery outside is none too shabby either!

The fanged jaws of the cat-like sabertooth Pogonodon

Skulls of oreodonts, vaguely sheep-like animals that are superabundant in the John Day fossil record

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.
