I wrote a piece for @theconversation.com about the top dinosaur discoveries of 2025, featuring Zavacephale, Istiorachis, Spicomellus, Nanotyrannus and Huayracursor. Research from @tweetisaurus.bsky.social @valdosaurus.bsky.social, Lindsay Zanno and more: theconversation.com/the-best-din...

Our first follow up from the Science paper: New paper on tooth morphology in the Grippia Bonebed - the oldest and most diverse Mesozoic marine tetrapod ecosystem. Paper open access here: njg.geologi.no/publications...

Then we have the Triassic symposium in the room with the massive screen... @elsa-panciroli.bsky.social, @stephanspiekman.bsky.social, and @davfoff.bsky.social shown here..

I’ve released a tool to sketch and edit phylogenetic trees! yawak.jp/PhyloWeaver/ Load a Newick file and intuitively add/remove/resize branches. Useful for quick conceptual trees, extracting subtrees, or turning ideas into Newick.

An Edinburgh family photo at the @societyofvertpaleo.bsky.social meeting. Soon after we lost my PhD advisor Mark Norell, it was special to be surrounded by the students and postdocs I’ve supervised!

Check out this #CORDIScovery podcast on how we study extinct animals, ecosystem and evolution in deep time. I greatly enjoyed learning and discussing our EU funded projects: #ECODIV, #DINODAWN, #MAPAS with @johnrhutchinson.bsky.social and Sara Varela!

#CORDIScovery podcast about my #DAWNDINOS Triassic-Jurassic archosaur locomotor biomechanics project, @davfoff.bsky.social's #ECODIV mass extinction/diversity/ecosystems project, Prof. Sara Varela's #MAPAS climate/biogeography/macroevolution project. Nice synergy! cordis.europa.eu/article/id/4...

Pre-SVP Exploring the Jurassic Coast field trip with amazing group of people led by @kirstymedgar.bsky.social & @davfoff.bsky.social. We explored classic fossil, geological and historical sights, fossil hunting and had a full British culinary and weather experience! #SVP2025 #2025SVP

The first #SVP2025 #2025SVP field trip has left, with @kirstymedgar.bsky.social & @davfoff.bsky.social leading a group to the Jurassic Coast of Dorset! I guess it’s too late to have second thoughts about hosting this conference now…

New @nhm-london.bsky.social 5-day course on integrative biodiversity discovery! Learn how to collect specimens, obtain genomic data, and interpret biodiversity using cutting edge phylogenomic analysis. It's free, and aimed at early career researchers: www.nhm.ac.uk/our-science/...

We've lost Dugie Ross, truly one of the best people I have ever known. He reported the first Scottish dinosaurs, made the Isle of Skye into Scotland's Dinosaur Island, welcomed so many of us onto his island, into his home and family.

We have lost the pillar of Scottish vertebrate palaeontology, Dugie Ross. The man that found & named Dearc. He made the science resonate locally, in his native language, on his native soil, while allowing it to grow globally. He embodied the best of science. Immeasurable loss.

A fascinating article by BBC News about the Dewars Farm Quarry dinosaur trackway excavation by scientists from across the UK and Oxford University Museum of Natural History, including some fabulous computer generated animation. Great stuff! www.bbc.co.uk/news/resourc...

A phenomenal paleontologist and a pleasure to talk to at SVP conferences. Mark will be missed.

#Fossil Files podcast fans!! Today sees the release of Fossil Fails II: The tiny dinosaur with the massive flaw... Get our take on that whole Oculudentavis thing - available now on libsyn and wherever you get your podcasts! @thefossilfiles.bsky.social fossils.libsyn.com/fossil-fails...

If you attend or work at a university in the UK, chances are you know someone who is on Indefinite Leave to Remain. Please consider what the recent attacks on ILR from both Reform and Labour are doing to those people you probably know.

If this plan is implemented, it will cripple British universities and health care, and tear apart families. All 'skilled' immigrants will require £60k salary & cannot use NHS. Permanent residence will be scrapped entirely. Citizenship made insanely hard. www.theguardian.com/politics/202...

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...

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...

I absolutely love this story by @jamesashway.bsky.social on he background about how we found Spicomellus

Hi all, me, @richardjbutler.bsky.social and the amazing UK-US-Moroccan team are delighted to announce that.. we have a new specimen of Spicomellus AND IT'S WAY WEIRDER AND WAY COOLER THAN WE EVER IMAGINED!!

It’s finally out! Our work addressing the origins of reptiles is published in PCJ! peercommunityjournal.org/articles/10.... We use novel info gleaned from the scan data of dozens of stem reptiles to substantially revise our understanding of early reptile evolution #paleontology #herpetology

Out today in Nature is the most exciting dinosaur paper I've ever been involved in - led by @tweetisaurus.bsky.social we describe a partial skeleton of the UTTERLY BIZARRE Spicomellus from the Middle Jurassic of Morocco, the oldest known ankylosaur. (1/x) www.nature.com/articles/s41...

I'm so excited to share my latest paper out now! How did the ancestors of mammals make the switch from sprawling to upright, taking over the world in the process? Spoiler alert; it's complicated! journals.plos.org/plosbiology/...

Nice article on our new little dino, Enigmacursor mollyborthwickae, named today by @tweetisaurus.bsky.social and me, and to be unveiled in a new permanent display @nhm-london.bsky.social tomorrow: www.bbc.co.uk/news/article...

New paper led by Tash Prescott - we applied equations for speed, etc that are commonly used on #dinosaur tracks to tracks made by living birds we could watch and time. TLDR: equations aren't even nearly close. Animals moving freely on compliant substrates very different to steady-state lab data

Richard Bambach will always be remembered as a champion of functional-ecological way of thinking in macroevolution. Way before the modern trend in analyzing functional diversity. onlinelibrary.wiley.com/doi/full/10.... 🧪 ⚒️ #Paleobio #Geology #EvoBio
