The Cerro Overo-La Invernada area in north Patagonia has provided a rich record of Cretaceous continental tetrapods in the last two decades, mainly from the Bajo de la Carpa Formation (Upper Cretaceous, Santonian). The dinosaur fauna from this area is diverse, including several new taxa, with abelisaurid theropods particularly abundant. Recently, a...

The diversity of the Upper Cretaceous (Cenomanian to Maastrichtian) crocodyliforms in Argentina is represented by several families of notosuchians (Notosuchidae, Comahuesuchidae, Baurusuchidae, Peirosauridae), and basal mesoeucrocodylian taxa. Most species (such as Neuquensuchus universitas, Notosuchus terrestris, Comahuesuchus brachybuccalis, Cyno...

Les fossiles des dipneustes sont principalement représentés par des plaques dentaires et des os de la mâchoire, alors que les crânes complets, ou presque complets, sont rares. Ici, nous décrivons un nouveau dipneuste du Santonien (Crétacé supérieur) de la Patagonie Argentine à l’aide de rendus tridimensionnels générés par des tomodensitogrammes. Il...

In the central Neuquén Basin, the Huincul Formation comprises thick successions of Upper Cretaceous fluvial deposits widely exposed at the south and north-west of Huincul High. The vertebrate fossil record from the Huincul Formation is very abundant, especially considering the saurischian dinosaurs, including several theropod (Mapusaurus, Taurovena...
Chapter
After the extinction of rebbachisaurids during the Cenomanian–Turonian interval, titanosaurs were the only group of sauropods to face the K–Pg event. This same global pattern also holds for the end-Cretaceous (Campanian–Maastrichtian) titanosaur record in South America, where their remains can be found from southern Argentina to Ecuador, with more...
Article
Full-text available
The Late Cretaceous theropod fauna of South America is composed of Abelisauridae, Noasauridae, Spinosauridae, Carcharodontosauridae, Megaraptora, and Coelurosauria. These groups include mostly small (Noasauridae and Coelurosauria) and medium- tolarge-sized taxa (Carcharodontosauridae, Abelisauridae, and Megaraptora). Some of these lineages are pred...
Preprint
Two new specimens of abelisaurid theropods from La Invernada fossil area (Bajo de la Carpa Formation; Santonian) are described. They correspond to an incomplete skull and several postcranial remains. MAU-Pv-LI-582 (skull) shares some morphological traits with other furileusaurs (Viavenator exxoni and Llukalkan aliocranianus) from the same area, as:...
Article
In the Neuquén Basin, the Portezuelo Formation (Turonian-Coniacian, Upper Cretaceous) is represented by extended fluvial outcrops that are well-known for yielding an abundant and diversified vertebrate fossil record. However, most of the sauropod fossil record is represented by incomplete specimens, and only two taxa are formally described for the...

Teeth with split carina is an uncommon trait recorded in archosaurs with ziphodont dentition (laterally compressed teeth bearing serrated margins). This condition has been reported in few theropod dinosaurs (Allosaurus, tyrannosaurids, dromaeosaurids and carcharodontosaurids) and in one Triassic phytosaur. Here, we report by the first time a split...
Article
Bite marks in non-avian dinosaur fossil records can constitute the best evidence of predator-prey interactions even if they are uncommon, ambiguous, or of uncertain origin. In this contribution, we present new evidence of feeding traces on an isolated sauropod element from Bajo de la Carpa Formation outcrops (Upper Cretaceous, Santonian), northern...
Article
Full-text available
Narambuenatitan palomoi is a titanosaurian sauropod from the Upper Cretaceous of North Patagonia. Considered initially as a basal titanosaur, this taxon has uncertain phylogenetic relationships within the clade. An X-ray Computed Tomography (CT) scan of the holotype braincase allowed the first reconstruction of the brain and inner ear of this taxon...

Several remains of an abelisaurid theropod including a nearly complete sacral complex articulated with both ilia, the distal boot of the pubes, the furcula, teeth, and fragments of transverse processes of caudal vertebrae was discovered in the La Invernada fossil site, northern Patagonia from the Bajo de la Carpa Formation (Santonian). The sacrum e...
Article
In the last decades, the Argentinian ornithopod record has been increased with new and diverse bone remains found along all the Upper Cretaceous. Most of them are very incomplete and represent taxa of different size. As result, the studies about the palaeobiodiversity of the Ornithopoda clade in South America are complex. In this paper, new postcra...

Dipnoi is a large group of sarcopterygians which ranges from the Early Devonian to the present. Traditionally, it was considered that their taxonomic diversity decreased at the end of Paleozoic. Dipnoans are abundant in the fossil record and their preservation state varies. The material study herein was collected in La Invernada locality, at 50 km...
Article
The type braincase of Viavenator exxoni (MAU-Pv-LI-530) was recovered complete and isolated from most of the other skull bones. Although the braincase is crossed by numerous fractures, using CT scans allowed the generation of 3D renderings of the endocranial cavity enclosing the brain, cranial nerves, and blood vessels, as well as the labyrinth of...
Conference Paper
The braincase of Viavenator Filippi et al. 2016 (MAU-Pv-LI-530) was recovered complete and isolated. Although crossed by numerous fractures, the endocranial morphology is perfectly observed using CT scans. In Argentina, abelisaurid partial endocranial morphology is only known for another two Cretaceous forms: Abelisaurus Bonaparte and Novas 1985 an...

Among the different lineages of turtles during the Cretaceous-Palaeogene, meiolaniforms (stem turtles) and pan-chelids (one of the Crown clades of Pleurodira) represent exceptional cases to perform any study because their diversity, evolutionary history, and geographic distribution. Besides, their fossil record in South America during that time is restricted to Patagonia providing an excellent base for this Project. In this Project we are performing detailed anatomical studies, inclusive phylogenetic analyses (including extant and extinct taxa) and diversity analyses through time and space to determine the patterns and processes of these clades during the Cretaceous and Paleogene. Comparisons of those results to geological proxies as well as other vertebrate groups could help to understand the impact of the K-Pg mass extinction event on those turtle clades. The results obtained in this Project will bring valuable information about the response of one of the most conspicuous clades of amniotes to mass extinction events.
Project
El proyecto iniciado en el 2012 en ésta particular área del norte neuquino, ha permitido recuperar una variada y abundante fauna de vertebrados (dinosaurios saurópodos, terópodos, ornitópodos, tortugas, cocodrilos y peces) que permitirá trabajar no solo en la sistemática y filogenia de nuevos taxones, sino en aspectos paleobiológicos, variabilidad intraespecífica y ontogenética, comparación con asociaciones faunísticas de otras áreas de la misma formación, cuestiones tafonómicas, reconstrucciones paleoecológicas, entre otras.
