Happy #MosasaurMonday from Eustace, the holotype skull of Jormungandr walhallensis discovered in North Dakota by the NDGS.
We were tasked with taking this not-quite-complete skull (right) and digitally restoring it for display at the NDGS as well as a library just a few miles from the dig site 🧪

#DAWNDINOS paper! We built a 3D musculoskeletal model of ~1 kg Triassic pseudosuchian archosaur Gracilisuchus. Forelimbs were a challenge. Nice articulations of ribs, vertebrae & osteoderms made a good torso & neck. Probably quadrupedal, plantigrade & not fully erect limbs. doi.org/10.1111/joa....

Diplodocid bones galore and aplenty at the Oertijdmuseum. Here some photos from a while ago of the construction of Aurora (a composite of two specimens). The skeleton was on display elsewhere for a month and is now being mounted in the Oertijdmuseum. Photos of that coming soon.

Of course the big paper on Azhdarchoid phylogeny comes out while I'm at a museum on a research visit (looking at Azhdarchoid cervicals, obviously) but now I'm back at the hotel so it's time to write a proper thread! 1/28

Our controversial paper is finally out in @cp-iscience.bsky.social !
As part of my PhD dissertation at @qubelfastofficial.bsky.social in 2021, the last chapter was dedicated to a specific pathological pattern in hadrosaurid tails!

CLUMSY MALE DINOSAURS INJURED FEMALES DURING MATING: Our new paper (Filippo Bertozzo et al. 2025), shows that a common tail injury seen in duckbilled dinosaurs was probably caused by heavy male dinosaurs clumsily crushing the spines of females during mating.

Nanotyrannus is real.
For years I’ve considered many mid-sized gracile tyrannosaurs to be juvenile T. rex.
But I was wrong. This stunning new skeleton of a mature long-armed small tyrannosaur is clearly a different species.
Isn’t science fun?!
