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

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!
Excited to announce that my second manuscript, “Fossilised Melanosomes Reveal Colour Patterning in A Sauropod Dinosaur” has been published in
@royalsociety.org !! Diplodocus scales are complex and diverse, and it turns out their color patterning was even more so. A 🧵🦕 1/26

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)

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.

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:

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.
