Took me a few minutes to figure out what I was looking at. The hand of the new alvarezsaur Manipulonyx, dropping two days before Christmas.

One of the all-time weirdest bits of dinosaur anatomy I've ever seen!

Il n'y a pas d'épisode significatif de froid en France depuis près de 5 ans.
➡️Il n'avait jamais fait aussi chaud pour un 8, 9 et 10 décembre depuis le début des mesures. La moyenne nationale française a d'ailleurs dépassé 17 fois son record journalier en 2025 (0 fois pour le froid).

Some days ago I made a thread on Pleistocene crocs in honor of Prehistoric Planet: Ice Age, and now I'm bringing it here too.
Let me prefice this by saying that I of course understand their absence, obviously more unique fauna takes priority and I don't begrudge the team their choice

GOOD NEWS for all Orthodox Jedi (reformed) practitioners: MIDICHLORIANS have been discovered!

Now the BAD NEWS: they've been discovered in Ixodes ticks.

"Candidatus Midichloria" are a real bacteria found in the ovaries of certain hard-bodied ticks & they DO have some unusual properties.

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)

On retrouve des très nombreuses dates qui sont également bien plus froides que ce que nous vivons comme en novembre 1968 ou 1985.

Bref, pour le moment, nous vivons un épisode totalement... banal.

Un ressenti ne fait pas le climat. Vous avez froid ? En réalité, d’un point de vue statistique… ce froid ne signifie absolument rien. Aucun record, même pas proche : on reste largement dans la zone normale de variabilité (la fameuse zone grise du graphique).

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.

Qu’est-ce que c’est, une machine à sous ?

Non, c’est une calculatrice à manivelle (type Odhner) fabriquée par Walther dans les années 60.

J’ai eu le plaisir — ponctué de frustrations — de la démonter et de l'entretenir cette semaine, ça m’a pris environ 25h.

Someone claimed ancient volcanoes emitted more CO₂ than humans ever could. The data says otherwise.

Siberian Traps (252 million years ago): 0.02–0.13 gigatons of CO₂ per year, over ~300,000–500,000 years
Humans today: ~36 gigatons per year
