Osteohistology of Aucasaurus garridoi (Dinosauria, Theropoda, Abelisauridae): inferences on lifestyle and growth strategy
(Taylor & Francis, 2022-04)
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 ...

Traços de mordidas em osso de dinossauro da Formação São José do Rio Preto, Bacia Bauru, Cretáceo Superior, Brasil
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERNCâmpus São Carlos, 2022-05-24)
By studying fossil bite traces, we can reconstruct the behaviour of extinct organisms
and better understand past communities, ecology, and ecosystems. Herein we analyse
bite traces on a fragmented sauropod rib from the ...
Modelización con Elementos Finitos de un Diente Referido al Género Giganotosaurus (Theropoda: Carcharodontosauridae)Finite element modelling of a tooth refrerred to the genus giganotosaurus coria and salgado, 1995 (Theropoda: Carcharodontosauridae)
(Asociación Paleontológica Argentina, 2004-12)
Se estudió cuantitativamente y por vez primera el diseño biomecánico del diente de un dinosaurio. Para ello se generó mediante tomografía computarizada una serie de imágenes transaxiales (separadas a intervalos de 1,5 mm) ...

Archaeopteryx, paravian phylogenetic analyses, and the use of probability-based methods for palaeontological datasets
(Taylor & Francis, 2013-05)
Archaeopteryx, which has often been considered the earliest avialan, is an iconic species, central to our understanding of bird origins. However, a recent parsimony-based phylogenetic study shifted its position from within ...
Bird embryos uncover homology and evolution of the dinosaur ankle
(Nature, 2015)
The anklebone (astragalus) of dinosaurs presents a characteristic upward projection, the 'ascending process' (ASC). The ASC is present in modern birds, but develops a separate ossification centre, and projects from the ...
Gondwanan perspectives: Theropod dinosaurs from western gondwana. A brief historical overview on the research of mesozoic theropods in Gondwana
(Asociacion Paleontologica Argentina, 2017-11)
THE study of Gondwanan non-avian theropods has beenoutstandingly prolific in the last three decades and hasshown that the taxonomic and morphological diversity ofthe group is comparable to that of Laurasia. The MesozoicGondwanan ...
New carnivorous dinosaur from the Late Cretaceous of NW Patagonia and the evolution of abelisaurid theropods
(Springer, 2009-03)
A nearly complete skeleton of the new abelisaurid Skorpiovenator bustingorryi is reported here. The holotype was found in Late Cenomanian-Early Turonian outcrops of NW Patagonia, Argentina. This new taxon is deeply nested ...
