Out today in @commsearth.nature.com from some of my newest colleagues at UMMP: evidence that the extinction of dinosaurs led to fundamental shifts in terrestrial environments, and that this signal is recorded in facies shifts tied to the K-Pg boundary: www.nature.com/articles/s43...

Incredibly proud and also very emotional to see this new paper published in @systbiol.bsky.social. The study was lead by Pierre Cockx, who sadly passed away in July. academic.oup.com/sysbio/advan...

Please share widely! The Natural History Museum Denmark @nhmdk.bsky.social is offering a PhD fellowship in collection-based Natural History Research, focused on dark taxa & unknown species, pref. including representatives of Danish flora, fauna or geology. candidate.hr-manager.net/ApplicationI...

Incredibly proud to see this project hit the light of day! Begun in the 1980s as the M.S. research of D. Govoni, I've led the charge with Dave the past few years to revise and expand his unpublished thesis and ensure that this diverse gastropod fauna received the formal description it deserved. 🧵

oooo! Serrated oral spines around the mouth on this lovely cidaroid urchin! Feeding on corals perhaps? #echinoday

Another video of our feeding experiment using fluorescent beads and bryozoan colonies (Membraniopora sp.). 💫

1 To predict the behaviour of a primate, would you rather base your guess on a closely related species or one with a similar brain shape? We looked at brains & behaviours of 70 species, you’ll be surprised! 🧵Thread on our new preprint with @r3rt0.bsky.social , doi.org/10.1101/2025...

Just wow 😵‍💫 #MolluscMonday

Do you like cichlids? Fossils? Fossil cichlids? Would you like to study them as part of a graduate degree at the University of Michigan, joining an NSF-funded project? Get in touch.

This #FossilFriday I have a sneaky surprise to share!! You might THINK this is a funky clam but ....

Postcards from the last #fossilfriday in the field 🦖🏜️⚒️

Shannon's H, Simpson's D, and Pielou's J are useless in ecology. Fitting data with a compound abundance distribution based on the geometric series is a better way to quantify variation – and to estimate species richness. New paper in Ecology Letters. onlinelibrary.wiley.com/doi/10.1111/...

LOVE papers about gut contents! Vampyromorph coleoid predation by an ichthyosaurian from the Early Jurassic Lagerstätte of Bascharage, #Luxembourg Valentin Fischer et al peerj.com/articles/197... (Seen thanks to @arctomet.bsky.social!)

When I was 10, I wrote to Mark with my ideas about dinosaur digestion. His response was encouraging, gracious, and part of what kept my interest in paleontology alive, and likely led in part to my path into education with high schoolers. Thank you, Mark. 2/2

You can examine a photogrammetric model of this specimen in our UMORF repository: umorf.ummp.lsa.umich.edu/wp/specimen-...

If you know anyone interested in starting a Master's project working on ammonoid phylogenetics (or the phylogenetics of a mollusc group spanning the OAE2 event in the Late Cretaceous), then ask them to get in touch with me. The situation is a little tricky, as it would be funded by the remainder…

Here is our newest paper just published in Scientific Reports TODAY about the biology of Early Triassic ichthyosaurs from Spitsbergen www.nature.com/articles/s41...

For this #FossilFriday the beautiful Gigantoconia princeps (Stoppani, 1860) with color preservation, from the Ladinian Esino Formation in Italy. ⚒️

New paper in which we evaluate how we can use information on past extinction events to better contextualise the ongoing anthropogenic extinction, led by @anthropocenebio.bsky.social (with @bethanyjallen.bsky.social, @inesismartins.bsky.social, & others): onlinelibrary.wiley.com/doi/10.1111/...

For #ThinSectionThursday, a bryozoan grainstone/rudstone from the Permian of Western Australia.

Huge thanks to @palaeopercs.bsky.social for inviting and hosting me! If you missed my talk on Tuesday, you can now catch up via their YouTube channel 👇 www.youtube.com/watch?v=x19X...

Did you know we are one of two journals produced by the Natural History Museum London. We champion the importance of collections-based systematics and our papers cover fossil species from across the tree of life, substantially contributing to the systematics of extinct taxa. So, why publish with us?

📊 new paper! The natural phenomenon of upwelling, which normally occurs every year in the Gulf of Panama, failed for the first time on record in 2025... www.pnas.org/doi/10.1073/... [most co-authors not on bluesky except @javsdiaz.bsky.social @jonscibulski.bsky.social]...

When an organism lives inside another organism, it is called inquilinism. Modern giant clams have shrimp specially adapted to live in their gill cavity. @paleoadiel.bsky.social and colleagues described inquiline shrimp in the body cavity of giant Cretaceous inoceramid bivalves! (224)

Cool case of [probably] pliosaur biting nautiloid! 🧪 ⚒️ #Paleobio #Geology #EvoBio www.scup.com/doi/10.18261...

Yo dawg we heard you like shells...the Stimpson chimney clam is a shell in a shell. These little bivalves bore into loose shells, building little chimneys of cemented shell fragments once they grow past the thickness of their host shell. (223)

We're looking for an applied mineralogist here in Erlangen! Earth Sci folk - please share the word! 🔨 🪨 💎 www.fau.eu/people/worki...

Talking about another true #invertefest: belemnite "battlefields" or "Schlachtfelder". Despite the name, they are generally used to refer to dense accumulations of #fossil #cephalopod rostra, which can be formed under various mechanisms. Irrespectively, they are a great way to obtain large samples.

And here is the second preprint 😅 #FossilFriday

If anyone wants to check our preprint 🧐 #FossilFriday

It's fair to say that not everyone was convinced by our identification. But now we have a much more complete skeleton, excavated by our UK-Moroccan-US team. Not only does Spicomellus have spikes fused to its dorsal ribs, it has metre-long spikes extending from a cervical half ring

Have you ever heard of #Spicomellus? It’s one of the world’s strangest dinosaurs. Its rib bone has spikes fused to it - something unheard of in any other animal! But now, more of the skeleton has been uncovered - and it's even stranger than anyone imagined... (1/4) 🧵

Here is a tiny pectinid bivalve Leptochondria from the Early Triassic of Pakistan. It is just 6 mm, but fully grown adults can reach 20 mm. #MolluscMonday

On the beach, if you see a "beard" on the little bean clams hoping around the surf, that is *not* a byssus from the clam, but in fact hydroids hitching a ride on the clam! Research suggests that clams bearing hydroids are less likely to be predated by moon snails, so it is a true mutualism! (198)

🚨Palaeoverse Lecture Series🚨 🗓️28th August 2025, 15:00 UTC🗓️ Join us for next week’s talk given by @sauropodlets.bsky.social from the University of Leeds, on “Modelling ancient food webs: ecosystem changes across the Pliocene marine megafaunal extinction” 🦈 Register here: bit.ly/palaeoverse-...

The ideas on the passive and active trends in the macroevolution of traits and complexity developed by S. Stanley, S. J. Gould and D. McShea become ever more mathematically operationalized. besjournals.onlinelibrary.wiley.com/doi/full/10.... 🧪 ⚒️ #Paleobio #EvoBio

For this #MolluscMonday here are the seashells of Wales: cockles (in Swansea), razor clams and mussels (in Rhossili).

New #ScienceCommunication website blog from me. Here, I look at another recent #megalodon study - one that used zinc isotopes & found that the giant shark wasn't just a whale killer; but probably ate whatever it wanted. Give a read here: www.drjackacooper.com/writing/mega... 🦈

Yeah sure that works as a field label

I was interviewed for this article. It's pleasing that a Moroccan fossil dealer confirms what I said the law was and clarifies that it isn't 'a grey area'. It's got nothing to do with UNESCO, btw John. www.cnn.com/2025/08/15/s...

Trilobite legs are rarely preserved. A few special locations preserve soft tissues and help us understand how trilobites walked and ate. This is a Triarthrus eatoni from Beecher's Bed in New York. #FossilFriday

#FossilFriday The first of several images that missed the cut for inclusion in 'Fossils. The Essential Guide' www.nhmshop.co.uk/fossils-the-... Resembling a sinistral gastropod, this is an internal mould of the Late Cretaceous ammonite Turrilites.

Really happy to see chapter 2 of my PhD published today in @methodsinecoevol.bsky.social. DeepDiveR is an R package to assist with deep learning inference of biodiversity change through time 🤿🦊 Thanks to @bethanyjallen.bsky.social & Daniele Silvestro for the collaboration doi.org/10.1111/2041...
