Our latest research on hadrosaurid tail injuries as possible sex indication was announced by @colbertlateshow.bsky.social , how COOL is that?????

Tomorrow I’ll be travelling to Birmingham for the meeting of SVP:
- present two posters
- meet so many friends and colleagues I haven’t seen for a long time
- planning scicomm projects with a few cool buddies
-networking a lot
I look forward to see all of you there! 🦕🦖

I want to thank all my amazing coauthors -especially my mentor Darren Tanke (who first hypothesized the mating hypothesis in 1989 -DARREN, WE DID IT!-), the many institutions that helped me, and the paleoartist Emiliano Troco for the illustrations!

there are MANY "but", "if", and biological implications.
The paper is published in OPEN ACCESS so you can read and give me your thoughts 😀

After this evaluation, we realize that the mating hypothesis was the one explaining the pathological pattern at best.
The mounting male presses on the female tail, causing the vertebral lesions on top of the spine.
November 4, 2025 at 7:28 PM
Knowing where we were going, we had to be sure. Or, at least, we had to consider EVERY OTHER SCENARIOS to explain what really looked like something related to sexual activity: predation, locomotion stress, strange and particular behavior, herd stepping... all of them were missing soemthing.
November 4, 2025 at 7:27 PM
This is the condition for the tails we could check, we also have many other vertebrae in the dataset
November 4, 2025 at 7:26 PM
After many years of work, submission, tears and swat, we can finally reveal it - hadrosaurids were likely injuring the female partner during sex.
For many years, many hadrosaur caudal vertebrae are found possessing broken neural spines, healing, and this has puzzled many researchers...

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!

For ABSOLUTELY NO REASONS AT ALL, here the two replica skeletons of the Russian lambeosaurines Olorotitan and Amurosaurus at the Institute of Narural Sciences of Brussels for #fossilfriday

… hehehehe 😏👀🦕

Just dropping here the wooden cast of the Olorotitan holotype for absolutely no effing reasons 😇

4th November 17.30 Rome time.
Less than a week.

Similar cousins, and yet so different animals!
See the skull of my new species Cariocecus bocagei -published this week- at the foot of the Iguanodon statue at @naturalsciences-be.bsky.social for #fossilfriday

However, the color pattern of Kratos was not ideal to what I had in mind. I prepared some palettes based on birds, but then I had an idea. I am a huge @criticalrole.bsky.social fan, and I wanted to tribute them. This, I applied Grog’s tones to the official reconstruction by Victor Carvalho!
September 18, 2025 at 12:47 PM
Cariocecus was the Lusitania God of War in the pre-Roman age. It was therefore instantaneous the association with the famous videogame franchise of Kratos 😁 hence, during the first days after deciding this new genus name, I had fun making this fake PS5 cover!

ah, I was forgetting: Cariocecus is named after the Lusitanian GOD OF WAR Cariocecus (before been renamed into Mars/Ares). And bocagei refers to 19th century Portuguese zoologist José Vicente Barbosa du Bocage.
Actually, I'll show u something funny in the next days on the genus name XD 13/x

Furthermore, the supraorbital membrane articulates solely with the lacrimal, and not with the prefrontal as in other ornithischians. This placed the bone ina lower level in the orbit, likely giving it a "mean" look 10/x
September 15, 2025 at 6:18 PM
However, I think the most interesting paleobio result we obtained is the reconstruction of the supraorbital membrane. This is a structure visible in birds as well, connective tissue covering the eye and achoring with supraorbital (the "eyebrow"), prefrontal, frontal, and postorbital 8/x

We used a new matrix to detect the phylogenetical position of SHN.832. Cariocecus resulted as a basal hadrosauroid together with Brightstoneus and Comptonatus. However, I am curious to see how it will change in future projects of mine (😏😏), especially adding Istiorachis and other species 7/x
September 15, 2025 at 6:12 PM
Cariocecus resulted to be indeed a new species. Crazy features are: jugal and maxilla are co-ossified, and the supraorbital articulates solely with the lacrimal! We were able tor econstruct via microCt the replacement teeth, brain and inner ear. I digitize the models, assembling them in Blender 6/x
September 15, 2025 at 6:04 PM
I visited SHN in 2019, and director Bruno Camilo )coauthor) showed me the specimen. Indeed, ti was worth a study! However, the 2020 pandemic halted the project, until 2023 when my supervisor Pascal Godefroit went to visit SHN, establishing a collaboration between the institutions 3/x
September 15, 2025 at 5:58 PM
The specimen, SHN.832, was found in 2016 by Pedro Marrecas of the Sociedade de Historia Natural in Praia do Area do Mastro, south of Lisbon. Pedro noticed a series of lined teeth in a boulder, likely felt from the cliff 1/x

Today new publication has been released in @journalsystpal.bsky.social
We are proud to present you Cariocecus bocagei, a new hadrosauroid from the Papo Seco Formation (Barremian, Early K) of Portugal.
Come with me in this post series to learn more about it! 1/x
September 15, 2025 at 5:54 PM
Tomorrow be sure to follow my accounts (here, IG, and YouTube) for my new publication!!
Here’re the spoilers I released during the past week.
The time is 11am UK time 😎🦖🦕
