Osteology of the unenlagiid theropod Neuquenraptor argentinus from the Late Cretaceous of Patagonia [PDF]
Acta Palaeontologica Polonica, 2017 Neuquenraptor argentinus was described as the first undoubted deinonychosaurian theropod from Gondwana. The only known specimen is represented by a fragmentary skeleton, including a nearly complete foot, coming from Late Cretaceous beds of Neuquén ...

A New Specimen ofAustroraptor cabazaiNovas, Pol, Canale, Porfiri and Calvo, 2008 (Dinosauria, Theropoda, Unenlagiidae) from the Latest Cretaceous (Maastrichtian) of Río Negro, Argentina [PDF]
Ameghiniana, 2012 There were considerable differences in Late Cretaceous faunas of the Northern and Southern Hemispheres, although the differences were breaking down during Campanian and Maastrichtian times with the appearance of hadrosaurids in Antarctica and South America, and titanosaurids in North America.

Paravian Phylogeny and the Dinosaur-Bird Transition: An Overview [PDF]
Frontiers in Earth Science, 2019 Recent years witnessed the discovery of a great diversity of early birds as well as closely related non-avian theropods, which modified previous conceptions about the origin of birds and their flight. We here present a review of the taxonomic composition

Anatomía comparada de los terópodos paravianos Unenlagiidae y sus implicancias en el origen de las aves [PDF]
, 2023 Paraves es el clado de dinosaurios que cuenta con mayor número de especies, ya que por un lado agrupa a terópodos no-avianos extintos como Troodon y Velociraptor, y por otro lado a las aves, únicos dinosaurios vivientes (Avialae: Dinosauria, Gauthier 1986), donde se cuentan más de 11.000 especies.

Unenlagiid theropods: are they members of the Dromaeosauridae (Theropoda, Maniraptora)? [PDF]
Anais da Academia Brasileira de Ciências, 2011 In the present paper we analyze the phylogenetic position of the derived Gondwanan theropod clade Unenlagiidae. Although this group has been frequently considered as deeply nested within Deinonychosauria and Dromaeosauridae, most of the features ...

A large Megaraptoridae (Theropoda: Coelurosauria) from Upper Cretaceous (Maastrichtian) of Patagonia, Argentina. [PDF]
Sci Rep, 2022 Megaraptora is a theropod clade known from former Gondwana landmasses and Asia. Most members of the clade are known from the Early to Late Cretaceous (Barremian–Santonian), with Maastrichtian megaraptorans known only from isolated and poorly informative ...
