New ichnological record from the late campanian Toro Toro Formation at Toro Toro, Potosí (Bolivia): first probable dromaeosaurid tracks from South America
(Asociacion Paleontologica Argentina, 2011-12)
Dromaeosaurids have a characteristic pes with a larger central third digit, a slightly smaller fourth one, and a second one represented by a ball-shaped pad that supported a retracted, deeply curved claw that did not come ...
A bizarre Cretaceous theropod dinosaur from Patagonia and the evolution of Gondwanan dromaeosaurids
(The Royal Society, 2008-12)
Fossils of a predatory dinosaur provide novel information about the evolution of unenlagiines, a poorly known group of dromaeosaurid theropods from Gondwana. The new dinosaur is the largest dromaeosaurid yet discovered in ...
Postcranial skeletal anatomy of the holotype and referred specimens of Buitreraptor gonzalezorum Makovicky, Apesteguía and Agnolín 2005 (Theropoda, Dromaeosauridae), from the Late Cretaceous of Patagonia
(PeerJ, 2018-04)
Here we provide a detailed description of the postcranial skeleton of the holotype and referred specimens of Buitreraptor gonzalezorum. This taxon was recovered as an unenlagiine dromaeosaurid in several recent phylogenetic ...

Differential locomotor and predatory strategies of Gondwanan and derived Laurasian dromaeosaurids (Dinosauria, Theropoda, Paraves): Inferences from morphometric and comparative anatomical studies
(Wiley Blackwell Publishing, Inc, 2020-02)
Tetrapod limbs morphology is a reliable proxy of locomotor capacities. Beyond this, other aspects of life habits, such as predation abilities, can also be relevant to determine main morphofunctional appendicular properties, ...
First evidence of an unenlagiid (Dinosauria, Theropoda, Maniraptora) from the Bauru Group, Brazil
(Elsevier, 2012-04-29)
In this study, we describe a small theropod dorsal vertebra from the Late Cretaceous Bauru Group (Brazil). The specimen is referred to the maniraptoran clade Unenlagiidae based on the following combination of characters: ...
Dentes fósseis de teropodomorfos da Bacia São Luís / Grajaú, Albiano / Cenomaniano do estado do Maranhão, e prováveis associações taxonômicas
(Universidade Estadual Paulista (Unesp), 2017)
Os dinossauros, assim como outros seres extintos, despertam a curiosidade do ser humano desde que foram conhecidos. Imaginar como estes seres viviam pode ser uma tarefa difícil, uma vez que não podemos vê-los em seu habitat ...
