For alle som trenger å lese nyheter om noe morsomt innimellom alt det andre: Min dyktige kollega @feikosaur.bsky.social har studert fossile ryggvirvler fra fiskeøglebabyer for å forstå graviditet og vekst. Moro og nyttig! 🐬🍼🦖 @forskning.bsky.social www.forskning.no/evolusjon-pa...
Takk for tilliten, selv om jeg alltid føler meg på usikker grunn med uttale på norsk, jeg kan fossile knokler bedre enn språk. Jeg selv sier Diplo-DO-cus når jeg tenker meg om, men det er kanskje dårlig begrunnet. Skal sjekke, og oppdatere snl hvis det er behov!

Judith Pardo-Pérez and I are organizing a dedicated ichthyosaur symposium at @ipc7.bsky.social 🤩 Hope to see very many interesting abstracts! Get in touch if there are questions.
Very interesting study by @feikosaur.bsky.social and Erin Maxwell about ichthyosaur fetuses!

My chapter is of course about a whale skeleton, a small Lagenorhynchus/Leucopleurus from the Natural History Museum @uio.no with a story that fascinated me.🐬 This volume and the project Collecting Norden gave an opportunity to write and think about whales in new ways. OA. brill.com/display/book...
In addition to sixteen chapters on different objects from our amazing colleagues, we wrote an introduction. It is behind a paywall, so let me know if you want a pdf brill.com/display/book...
Published book🥳Janicke Kaasa, Ulrike Spring and I edited the volume Collecting the North in @degruyterbrill.bsky.social series Arctic Humanities. It examines natural and human-made objects from 18th-20th century, their relationship to Nordic countries and European Arctic. brill.com/display/titl... 🧪
Arctic plants, ichthyosaurs and more! We received funding from Nordforsk for a Nordic network for convergent evolution #NCEN! It is led by @siribirkeland.bsky.social and me, hosted at the Natural History Museum @uio.no and include researchers with amazing work🥳 www.nordforsk.org/projects/nor...

I årboka 2025 for @universitetsmuseet.bsky.social 200 år har jeg skrevet om museumssamlinger og forskning i fortid og framtid, sammen med Anders Goksøyr og Rein Aasland. // Text in yearbook for the museum in Bergen about collections and research 🐋🏛🧪 (In Norwegian) um.uib.no/3001UMB2025F...
We find no significant difference in inferences when using the humerus compared to the femur. Also, we found that mean corpuscular volume is correlated to the harmonic means of vascular canals. Both give more opportunities for what data can be used when we want to understand vertebrate physiology🫎🐬🧪
New paper from the ECHO project 🥳 Does the upper arm bone tell us the same things as the thigh bone if we look inside?💪🏼🦵🦴 Lead by Mathieu G. Faure-Brac, we investigated how we can expand the available input data to be used in paleophysiological models.

Thank you for a great conference in Birmingham #2025SVP with the Natural History Museum @uio.no team🤩 @aubronectes.bsky.social @feikosaur.bsky.social @meghalithic.bsky.social Petter Nordenhaug and Mathieu Faure-Brac
Look what my amazing colleagues did! Early Triassic bonebed at Svalbard shows recovery after mass extinction🥳 @aubronectes.bsky.social
Petter Nordenhaug, also Natural History Museum @uio.no has a great poster on mixosaurs

All from the Natural History Museum @uio.no 🤩
Myself on swimming evolution in ichthyosaurs and whales 🐬🐬🐋 Talk in Hall 4 Thursday at 0815.
Feiko on neoichthyosaurian pelvic girdle evolution 🐬🍼 Talk in Hall 4 Thursday at 0845🤩
Mathieu presents the first results from our work on ichthyosaur metabolism🐬🌡 Poster session on Thursday 🤩
We are at #2025SVP and having a great first day! From the ECHO and EXPLAC projects in our group postdocs Mathieu Faure-Brac and @feikosaur.bsky.social. Our marine tetrapod presentation times below 👇
Veldig fin tekst om evolusjon av vinger og flyving av vår student Aylin Gjøringbø i siste nummer av Biolog🤩 @feikosaur.bsky.social / Talented student Aylin Gjøringbø in our group just published a great essay about the evolution of fight (in Norwegian).
In short: As long as you remember Jurassic World is not a documentary, enjoy🍿
Jeg fikk diskutere Jurassic World Rebirth i siste utgave av @forskerforum.bsky.social. Det er bra for all biologisk forskning at folk liker dinosaurer, og så lenge man husker at det ikke er en dokumentar kan man slippe å bli surmaga. Men: marine reptiler er ikke dinosaurer, såpass forventer jeg 🐬🦖🦕
My comment: Is scale loss always part of evolving a pelagic lifestyle? Is Is always about swimming? Maybe - or maybe not. Conclusion: More fossils and research needed🤩🧪

Interesting new study about scale loss evolution in turtles, with the oldest soft tissue preserved in a sea turtle 🐢 www.sciencedirect.com/science/arti...
Special congratulations to our own MSc student Marthe who won one of the Best talk awards🥳🐍 @feikosaur.bsky.social
