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.

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.

This is the condition for the tails we could check, we also have many other vertebrae in the dataset

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!

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!

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.

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

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

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

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
