Today I presented my half-time seminar, showcasing the first two chapters of my PhD project and the work that has been completed so far on chapters 3 and 4. A big thank you to everyone that has helped me get this far; I hope to share even more with you soon 🙂 .

Spawn season

I’ll start to regularly post photos of Lebanese fossils alongside links to charities supporting the thousands displaced in this war. Even the smallest donations can save lives Fossils on display at Memory of Time, Jbeil, and you can donate here: gofund.me/24a3cee49

Osteichthyans--the bony fishes--are by far the most diverse group of living jawed vertebrates. Two papers out today in @nature.com feature remarkable new Chinese fossils that paint a picture of substantial morphological diversity among stem osteichthyans.

The second reports a tiny (~3 cm) articulated fish from the early Silurian. The material is challenging, but it is unquestionably a bony fish. Fittingly named Eosteus, it co-occurs with the oldest articulated jawed fishes and cements the antiquity of osteichthyans. www.nature.com/articles/s41...

Last night I was down a rabbit hole of why fish can't exist deeper than around 8000 meters and I realized that the deepest a fish has ever gone in the ocean and survived was in a submersible. The fish were people. All vertebrates are fish. I hope this helps with ~~the horrors~~

We will be updating this page with news and further details, so please follow us to stay in the loop. Until then; Välkommen, och vi ses alla nästa år! #ISELV #ISELV19 #ISELVUppsala

This February, the Uppsala team attended and presented at the 18th ISELV in Berrechid, Morocco, sharing our research with the global early vertebrate community #ISELV18 @iselv18.bsky.social

Following on from our post yesterday, we are honoured to announce that we will be hosting the 19th International Symposium on Early and Lower Vertebrates (ISELV) meeting here in Uppsala in 2027! #ISELV #ISELV19 #ISELVUppsala #fossilfriday

“awful people don’t deserve to be killed, but they don’t deserve to be praised, either” is apparently a thought too complex for the pundit mind

A team from our lab recently joined fieldwork organised by the University of Latvia, helping to excavate fossils from the Devonian, including armoured fish (Placoderms) and early tetrapods in western Latvia. #fossilfriday #paleontology

Subject close to my heart - finding an ammonite on the Isle of Wight as a 6 year old started my love of geology / earth history. The Island has an incredible fossil wealth and really deserves world class facilities to display and project on the world stage! chng.it/kQKV2mLQdZ

Fossil(and more?) Friday. The Staruni Woolly Rhino was incredibly preserved with its skin in a condition good enough to be taxidermied. Her horns, hooves, hair, and guts were all that was lost, but you can see the individual follicles in her skin. #fossilfriday #EAVP2025 #MuzeumPrzyrodnicze

As part of our Faculty Inaugural Lecture Series—showcasing the work of our recently promoted Professors—Professor Clive Trueman delivered an engaging lecture, Using Chemistry to Unveil the Hidden Lives of Fishes. @clivetrue.bsky.social Watch here 👇 youtu.be/LujaS7cpHxc

When it comes to understanding when animals first walked on land, finding footprints of animals that literally pressed their feet into the ground absolutely holds the key. Congratulations to all authors including my former supervisor: @perahlberg.bsky.social www.nature.com/articles/s41...

Out Now in Nature! Amniote tracks from Australia push the timeline for terrestiality back 35 to 40 million years, with implications for our understanding of tetrapod evolution. www.nature.com/articles/s41...

One minute you’re king of the gods, the next you’re sending out spam for predatory journals.

The Biology PhD school asked me to write a blog post about my research, now it’s up and I can go back to staring at fish www.uu.se/en/departmen...

We are pleased to announce the opening of our new Tomography Support Center, now available for all @uu.se employees and students. We welcome collaborations with anyone interested in using microCT and synchrotron scanning. Learn more here: www.uu.se/institution/...

PeerJ Congratulates Elsa Leflaëc & Victor López Rojas - Award winners at The 5th Palaeontological Virtual Congress Learn more about their research on the PeerJ blog bit.ly/42EHFPA #5thPVC #Palaeontology @palaeovc.bsky.social

Interesting new find, presumably washed in from the Wealden….

A new paper for the new year 📰 How can we visualize changes in chemical composition of fossil teeth and scales? @matthewbc.bsky.social and colleagues discuss in: peerj.com/articles/187... #Palaeontology #biogeochemistry

Looking to read more this year? Why not start with my new article published today in @Peerj on how we can tell if original minerals are preserved in fossils. #paleontology #biogeochemistry peerj.com/articles/187...

The current cover of Nature spotlights the new paper on reconstructing food webs and the rise of dinosaurs through coprolites, by Qvarnstrom et al (ft. @grzegorzniedz.bsky.social and @perahlberg.bsky.social). Read more at: www.nature.com/articles/s41...

The new paper from our lab has dropped! 🧪 www.nature.com/articles/s41...

The early evolution of Tetrapods and the transition from water to land is a core focus of our research. Learn more about our ERC-funded project "Tracking our ancestors across the Devonian world" at our website: www.uu.se/en/departmen...

🚨Paper alert!🚨 A major paper from our lab, on which I had a very minor role, is dropping on Wednesday. Can't say more for now, but here's a teaser:
