Really proud of the excellent final course presentations by our lab's undergrad students! From marine turtles to snakes of all kinds, their projects were super interesting (and the slides were amazing!). Huge congrats Jorge, Gabriela and Sofia!

Lastly, it was great to see so many old friends after a long time and also meeting some folks for the first time in person! Thank you so much for the organising committee (@cpeg-cpb25.bsky.social) for delivering such an amazing talk! It was a blast!

Our postdoc Thayara Carrasco did not manage to attend in-person, but made herself present with a pre-recorded talk. I also had the pleasure to represent @mnritter.bsky.social during the poster session and to help organising a @palaeoverse.bsky.social workshop.

Proud supervisor moment! 🥹🤩
So incredible to watch our undergrad students from the lab shine in front of such a knowledgeable audience at @cpeg-cpb25.bsky.social. They absolutely crushed it and I couldn’t be prouder!

Super proud of our lab students for their final course presentations: Luan Estevão defended his MSc on elasmarian ornithischians; Kamila Lima presented a poster on her undergrad research in conservation paleobiology of freshwater turtles; and @fernandalandim.bsky.social and Pedro Kenji+

The 3D models and morphofunctional analyses also helped us inferring hunt strategies. We suggest some sort of niche partitioning between the two Speothos species, with the extant S. venaticus more restricted to smaller preys, in contrast to the more generalist S. pacivorus.

Multiple approaches were used, including traditional comparative morphology, but also geometric morphometrics and finite elements analysis (FEA). The results support S. pacivorus as a valid species, significantly different from other Cerdocyonina (including other extinct species)

The paper was led by Juan Ruiz (now a postdoc), as part of his PhD finished last year. The idea was to examine the fossils of S. pacivorus (housed in Denmark), compare to closely related taxa (such as the extant bush dog, S. venaticus) and reassess its validity.

Yes! Another AMAZING paleoart by Júlia d'Oliveira just dropped!
It showcases the Pleistocene bush dog (Speothos pacivorus) from Brazil, in association with our new paper published in JVP (link below 👇).

And to finish the paleontological tour in Villa de Leyva, look at this wall made of Early Cretaceous ammonites in the middle of the town! Truly incredible!

And today we also went to another nearby museum (Museo Comunitario El Fosil), in which they keep this amazing pliosaur specimen: Monquirasaurus boyacensis. It's skull is 2.7 meters long!

Super happy to have visited this amazing museum and research center (Centro de Investigaciones Paleontológicas) in Villa de Leyva, Colombia. The fossils are l impressive, as well as the exhibition itself! Hope to come back, at some point. 🇨🇴🦖🦴

Phylogenetically, we recovered Barreirosuchus within Itasuchidae, together with Itasuchus, Pepesuchus and others. It's worth mentioning that we followed the recently published phylogenetic nomenclature for Notosuchia, by Leardi et al. (2024).

Thiago did a fantastic job redescribing the material, comparing it with many other notosuchians. The CT scan also allowed us to reconstruct the endocast, providing valuable information for croc paleoneurology.

Barreirosuchus was collected some time ago, in rocks of the famous Adamantina Formation. A few years later, Iori & Garcia (2012) described the cranial and postcranial elements known for this taxon. In our new study, we focus on the cranial material, also using CT-scan data.

New croc paper alert! 🐊🚨
In this new study led by my friend and colleague Thiago Fachini, we reassessed the cranial morphology and phylogenetic position of Barreirosuchus franciscoi, a peirosaurian from the Late Cretaceous of Brazil.

Super proud of my very first student that presented today the results of her undergrad project. It was an absolute success (after a lot of hard work)! Congrats, Ana! 🐊

This is also interesting if we consider the geographical distribution of caimanines across the Cenozoic, which became more restricted to tropical regions as the planet cooled down after the Eocene.

This is also interesting if we consider the geographical distribution of caimanines across the Cenozoic, which became more restricted to tropical regions as the planet cooled down after the Eocene.
However, perhaps the most important result emerged when we separated species in large (> 3m) and small-sized (< 3m) categories, which showed that large caimanines are restricted to places with higher mean temperatures and low seasonal variation.

Our results show significant correlations between caimanine body size and the climatic variables (especially mean annual temperature and seasonal variation in temperature), although the relationships are too strong.

We then teamed up with a group of paleoclimate experts from the University of Bristol, allowing us to estimate climatic variables for the localities of most known caimanine species using a General Circulation Model. We also estimated body size for many more species.

The real size of these giants has always been subject of debate. Because of that, a previous paper also led by Ana Laura estimated the body size and mass of large-sized caimanines from the Miocene. Check more in the paper:
