NEUES BUCH Ich freue mich, die bevorstehende Veröffentlichung meines ersten Buches „Die Welt der Plesiosaurier – Paläontologische Abenteuer“ anzukündigen, das ich gemeinsam mit Achim Schwermann geschrieben habe und das Joschua Knüppe (@joschuaknuppe.bsky.social) eindrucksvoll illustriert hat. 1/4

Result from the Agate Fossil Beds #paleostream! This early Miocene lagerstätte from Nebraska (USA) is a fantastic window into our understanding of the transition from forest communities to grassland biomes...

Next Tuesday evening I'm giving an online seminar on Spicomellus for our funders, the British Institute of Libyan and Northern African Studies. It's free and anyone can come! Sign up here if you're interested us02web.zoom.us/webinar/regi...

This final version of this work is now available as a PDF. On behalf of my co-authors, I'd like to thank the editors and reviewers for their expertise and handling of the manuscript. www.ameghiniana.org.ar/index.php/am...

This year was one of my personal worst - however, I don’t want to lose hope. Not when I still can do stuff that I love, not when I find sometimes good. Anyways, some highlights of my 2025, with a lot of appreciation for the people that I met and opened their arms. Here is a short thread with images

Merry Christmas 🎄✨

Merry Christmas, to one and all!

🎉 Congratulations to Scripps Oceanography master’s student Rhowan Ho who has been selected for the 2026 Museum of Science, Boston Digital Science Communication Fellowship that supports emerging scientific leaders in mastering digital storytelling, strategic communication and public engagement!

Super cool stuff!! Tess has put a massive amount of work into this project, and the end result is really incredible. Certainly worth a read, and major congrats to @tessasaurus.bsky.social and the rest of the team!

9 December 1833: In Lyme Regis Elizabeth Philpot writes to Mary Buckland in Oxford to tell her that Mary Anning was almost killed by a cart on the narrow bridge over the River Lym as she was heading for the beach before dawn. This was one of at least 6 occasions when Mary narrowly escaped death.

I went today to a very small museum in Niederweningen as they found several wooly mammoths while building the small city in #Switzerland. Lovely staff, cute exhibition and a nice example how your own home can add something wonderful to a big picture. #museums #paleontology

Very excited to share that our latest paper is out in Science! We show that the type specimen of Nanotyrannus—an isolated skull—is fully grown, showing that it is not a juvenile Tyrannosaurus rex but a distinct species (1/12) www.science.org/doi/10.1126/...

The final, formatted version of the Zanno & @jgn-paleo.bsky.social Nanotyrannus paper is out: Zanno, L.E., Napoli, J.G. Nanotyrannus and Tyrannosaurus coexisted at the close of the Cretaceous. Nature (2025). doi.org/10.1038/s415...

Yes, there was a deliberate push to get rid of all scientific names; of course, I think this is a massive mistake. And, indeed, no roaring for sabretooths, their hyoid anatomy indicates that they couldn't do it :) #PrehistoricPlanetIceAge

Observations on #PrehistoricPlanetIceAge: wonderful, of course. But a strange reluctance in narration to a) state where in the world a scene takes place and b) use genus names. Odd, since no such reluctance in the Mesozoic series.

#PrehistoricPlanetIceAge >Showcasing large caves >Having cavehyena debut >Having the best cave lion design >showing peaceful carnivores >Lion gets eaten anyways because Disney villain (huh?) >no elaboration on the absurd cave complexes in the Pleistocene (Need a cave lion version of that meme)

You vs. the big cgi cat in the snow they told you not to worry about #PrehistoricPlanetIceAge

Years of work involving an amazing team at BBCSstudios Framestore AppleTV, our series #PrehistoricPlanetIceAge is out now on #AppleTV. Huge thanks to everyone involved. All 5 eps have been released!

I just watched #PrehistoricPlanetIceAge completely and would love to share some thoughts. Overall - @tetzoo.bsky.social and team, as always, amazing work! I generally loved the show and that it actually differs from earlier seasons. As I enter spoiler territory, I will add the next thoughts below:

The holotype of #Stenokranio boldi at the Geoskop Urweltmuseum #fossilfriday

Congratulations to @jeremywyman.bsky.social et al 2025 for the publication of their Oxroadia paper! And thanks for bringing me onboard to do some restorations of this relative of Lepidodendron and Isoëtes from the Carboniferous of Scotland. academic.oup.com/aob/advance-... #FossilFriday #paleobotany

Have learnt from Andrea Cau that French palaeontologist Philippe Taquet died yesterday, aged 85. Taquet published a substantial amount on north African and French #dinosaurs, including Ouranosaurus, spinosaurids, the dromaeosaurid Pyroraptor and much more.

@tetzoo.bsky.social for my mental health - does the brave kitty from #PrehistoricPlanetIceAge survive the conflict with the evolutionary middle finger of an otter?

Liebe dt. Wissenschaft, von mir verlangst Du seit Jahren vollstes Commitment. Von Dir bekomme ich im Gegenzug nichts als maximale Unverbindlichkeit. So kann es mit uns nicht weitergehen. Deshalb schreibe ich Dir diesen Brief — nachzulesen heute in meinem Newsletter #ArbeitInDerWiss! #IchBinHanna

Correlation is not causation.

I would like to use this morning to share a crowdfunding that my colleagues established for a project that is close to my heart experiment.com/projects/rea... I quickly summarize the goal and idea in the answers with a thread

With great pleasure I would like to introduce you to the first ornithomimosaur from Germany! The fossils of this charming bugger are from Balve, a locality that preserves early Cretaceous fossils in a Devonian reef that had karstified already back then, giving us: cave dinosaurs

Very excited to present the first ornithomimosaurs from Early Cretaceous of Germany. Artwork by @joschuaknuppe.bsky.social and the paper is OA: www.app.pan.pl/article/item... Enjoy! More is to be described from this place

I was yesterday in a small dinosaur park in western Germany and they randomly have models and exhibition stuff for "the future is wild". WHAT

Some nostalgy hit me and one of the coolest paleoart moment I had was having @joschuaknuppe.bsky.social making a #spinosaurus on request, printing it out for a small exhibtion and realizing what the art actually can look like. (Note: The zebra stripes were not my idea)

A little addendum to #Tameryraptor, with this info-graphic, showing the superficial differences between it and the neotype of Carcharodontosaurus.

Was Habeck sagt: Musk ist nicht dumm. Trump ist nicht dumm. Rechte sind allgemein nicht dumm. Sie wissen genau was sie tun. Sie arbeiten jeden Tag daran die Grenze des sagbaren zu verschieben. Wer das als dumm bezeichnet verharmlost das Problem und ist damit Teil desselben.

This cervical vertebra of a diplodocid at the Naturkundemuseum Reutlingen is my pick for this #fossilfriday - a fun connection to a lot of what I want to do and what I already learned More about it hopefully in the future

Mamenchisaurus is best known for its extraordinary long neck, however it also has a surprisingly slender head. With most artwork focusing on the neck the oddity of the skull is somewhat lost. But when you change perspective... #paleoart #sciart #paleostream

From the smallest to the largest new dinosaur in our museum – here is the tale of H.Q. 1, the largest of the Siber Collection dinosaurs making the new Natural History Museum UZH its home in this 2nd part of the #NMZChronicles 1/n (📸 Lukas Keller)

My #2024, thankfully got some #museum and some #paleontology - May 2025 evolve into something better

Welp.. no big Christmas miracle on the horizon, being jobless at the beginning of next year and all that 2024 threw at me.. I finally learned again to appreciate the small things. Time is a gift and curse, but used it!

Studies of the elephants for which we actually know what the size and morphology of external ear looks like. From left to right woolly mammoth, asian elephant, savannah elephant, forest elephant. Scaled to around same head size

Diplodocoids, #sauropods that are fun. #dinosaurs

Bell Burnell's male colleagues received the Nobel Prize for her discovery of pulsars. Perfect time to remember the ‘Matilda effect’, a term coined by Margaret W. Rossiter to describe the bias against recognising the achievements of women scientists.

Despite my voice turning into an old car engine, I had a blast in Zurich this year! I hope my path leads again to the amazing people and museums that welcomed me so kindly. (Whether as a guest or something more..☺️)

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

This is me the next days at two museums with paleontological collections - and I love it

If there is anything that excites me as much as diplodocid to study, it probably would be a big cat or machairodontid. And using a quote by a TV host to answer about other mammals ''This is brilliant! But i like this.'' Hope to see more cats in different exhibitions (and maybe outside of museums)
