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

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?!

If you like #dinosaur behavior, I think you’ll go CRAZY with my new upcoming paper.
The biggest and last chapter of my PhD.
Hint: Olorotitan.
I think MANY people will talk about this…

For those curious about the 3d model, it's the humerus of Pteranodon sp., FHSM VP 2183. Since this is already a fairly well described genus, I'm not gatekeeping the 3d model until publication, since this is just comparative data. Download it here: www.morphosource.org/concern/medi...

Spiny friends!
Stegosaurs bore a fantastical variety of bony plates, spines and osteoderms, probably a mix between ornamental, defensive and offensive.

Edmontosaurus annectens is in the news, and it made me remember of this oldie (2016) work. Something unusual tried here that got more or less confirmed from the new mummies is how a midline crest starts at the neck, and near the hips starts to transition to spikes that cover the tail!
