Interesting preprint suggesting that recently described fossils from Brazil described as a new ctenochasmatine pterosaur, Bakiribu, preserved within a regurgitalite, instead represent the gill arch apparatus of an actinopterygian fish:

The "caudofemoralis longus" is a muscle that leaves obvious evidence of its existence on the bones of dinosaurs. This muscle that retracted the leg during locomotion was anchored to the thigh bone at the 4th trochanter (see pic, labeled "d" where the bone is deformed by musc stresses) & to the tail.

There were so many big paleo publications made this year, especially in the last few months. First sauropod with gut content, nanotyrannus X2, new hadrosaur mummies, new pterosaur in vomit. You think any more big things will come before the year ends????

Re‐evaluation of a soft crested Edmontosaurin, with implications for hadrosaurid life appearance and diversity
Hadrosaurid dinosaurs are generally regarded as “crested” or “non-crested” depending on the presence or absence of a bony cranial crest. At least one supposedly “non-crested” hadrosaur is known to ha...

What might be my favourite fossil has been just published by Kiat et al. 2025. Years ago I saw a pic of this Anchiornis specimen in nat geo article and I audibly gasped.preserving not only the feathers but also the original patterns as well. I made this drawing on the spot. Maybe its time to do v2.0

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.

it seems that hadrosaurs were getting a little freaky with it 🤔 bertozzo et al. propose that the prevalence of tail pathologies in hadrosaurs suggests that these injuries were incurred during procreation

The problem with Nanotyrannus is that the remains people argue over aren't mature animals, leading many researchers to conclude they're just young T.rex (even if that idea also presented some sticky problems.) To finally settle it, folks said, you'd need to find a Nanotyrannus adult.
They did.

The abelisaurid line of carnivorous #dinosaurs likely had a wide range of skin patterns on their head - as noted and mapped by Delcourt (2018). His conclusion: some areas were likely adapted for social behaviours like intraspecies combat. Increasingly armoured heads seem to be a derived trait.
