En particular, existen excelentes afloramientos en el Área Natural Protegida “Paso Córdoba”, 15 Km al suroeste de General Roca (Rí...
Article
The Lohan Cura Formation (Albian) at the Cerro de los Leones locality (Neuquén Province, Patagonia, Argentina) yielded several fossil materials, especially sauropod specimens. Among these, Agustinia ligabuei includes postcranial elements of a single individual, with widely debated taxonomy and phylogeny. Here, we provide an extended osteological de...
Article
Skorpiovenator bustingorryi is a derived abelisaurid theropod represented by a fairly complete skeleton from the Late Cretaceous sedimentary beds of north-western Patagonia. Although some features were described in the original paper, mainly related to the skull, the appendicular anatomy remains undescribed. The aim of the present contribution is t...
Conference Paper
Non-avian theropod dinosaurs were pivotal components of Mesozoic ecosystems, spanning a wide array of trophic niches that lead to the diversification of tooth shape and dental morphologies (Torices et al., 2018; Hendrickx et al., 2019). In Europe, the Upper Cretaceous theropod fossil record mainly consists of isolated teeth and fragmentary bone rem...
Article
Abelisaurids are medium–large-sized theropod dinosaurs that were predominant in the carnivorous fauna during the Late Cretaceous of Gondwana. These predators are abundant in the Cretaceous fossil strata of Patagonia, which yield the best record for this group. In the Late Cretaceous, abelisaurids appear in almost all regions of Gondwana and in all...

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...
Conference Paper
Full-text available
Abelisaurids were dinosaurs that diversified specially in Gondwana during the Cretaceous. They were medium to large sized theropods, with reduced forelimbs, highly modified cervical vertebrae and sometimes had horned skulls. Their fossil record is abundant and well-represented making possible to assess the evolution of craniocervical musculature in...
Article
Although osteohistology has proven to be useful to discern several palaeobiological traits and systematics in non-avian dinosaurs, the bone microstructure of several groups (e.g., abelisaurid theropods) is still poorly documented. Here, we provide a microstructural description of different bones (a cervical epipophysis, three dorsal ribs, three gra...
Article
Osteological knowledge of the sauropod dinosaur Ligabuesaurus leanzai is increased by the description of new postcranial elements assigned to the holotype MCF-PVPH-233. Furthermore, a newly referred specimen, MCF-PVPH-228, is recognized after a detailed revision of the abundant sauropod material collected from the Lohan Cura Formation outcrops in t...
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...
Article
Aerotitan sudamericanus, from the Upper Cretaceous of the Neuquén Basin (Patagonia, Argentina), is known from a partial jaw fragment which has been interpreted as either an azhdarchid upper jaw, azhdarchid lower jaw, or thalassodromine upper jaw (as the sister-group of Alanqa). Here, we compare it in detail to upper and lower jaws of taxa belonging...
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...
Conference Paper
Full-text available
The complete and well-preserved osteological fossil record of the craniocervical region in some large theropod dinosaurs has made it possible to assess different feeding styles. We have reconstructed the cranio-cervical myology and range of motion of the abelisaurid Carnotaurus sastrei from virtual vertebrae scanned via photogrammetry. The results...
Article
The discovery of theropod shed teeth associated with sauropod remains is relatively common in Cretaceous deposits of Patagonia. However, only a handful of studies have thoroughly explored the phylogenetic affinities of the theropod dental material. Here, we describe and identify twelve theropod shed teeth associated with a partially complete skelet...
Article
Abelisauridae is a theropod clade with a wide distribution in the Late Cretaceous of Gondwana. Some of the best preserved abelisaurid specimens were recovered from Patagonia (Argentina) such as Skorpiovenator, Ilokelesia, Carnotaurus and Aucasaurus. Here we describe a dorsal part of a neural spine; a middle caudal vertebra; a distal part of a left...

Xenotarsosaurus bonapartei was the third abelisaurid theropod dinosaur to be named from Argentina. The holotype comprises two partial anterior dorsal vertebrae and a complete right hind limb from the Upper Cretaceous (lower Cenomanian–upper Turonian) Bajo Barreal Formation, central Patagonia, Argentina. The materials display morphological features...
Article
Dicraeosauridae is a family of small body-sized sauropod dinosaurs that diversified from the Middle Jurassic to the Lower Cretaceous, whose distinctive feature is a long dorsally projected, bifid neural spines in most of the presacral vertebrae. The dicraeosaurid fossil record is limited to few taxa, therefore each new finding, however fragmentary,...
Article
A new ceratosaurian theropod dinosaur, Huinculsaurus montesi gen. et sp. nov., is described here. This taxon is based on the last three dorsal vertebrae and the first and second sacral vertebrae found in association at Aguada Grande, Neuquén Province, Argentina. Although fragmentary, Huinculsaurus shows a unique mix of features which differentiates...

Alvarezsauridae is a group of small-sized coelurosaurian theropods, known from Upper Cretaceous deposits of North America, Asia and South America. Although many new alvarezsaurid species have been recently discovered, and the knowledge of their anatomy has largely improved over the last decade, the phylogenetic relationships of Alvarezsauridae are...
Conference Paper
Full-text available
The Megaraptora is an intriguing taxon of medium-sized theropod dinosaurs with disputed phylogenetic relationships. Depending on the chosen characters to be scored, megaraptorans can be understood either as the sister group of Carcharodontosauridae, or the sibling taxon of Tyrannosauroidea. Despite this unresolved phylogenetic scenario, the number...
Conference Paper
Full-text available
From the pioneering work of Currie and collaborators at the beginning of the 90's, a large number of qualitative and quantitative parameters began to be established and systematized, with the aim of achieving a more precise classification of isolated theropod teeth. Due to exposure of these materials to taphonomic processes, the missing data are re...

Luxuriant, bushy antlers, bizarre crests, and huge, twisting horns and tusks are conventionally understood as products of sexual selection. This view stems from both direct observation and from the empirical finding that the size of these structures grows faster than body size (i.e., ornament size shows positive allometry).We contend that the famil...
