A new baurusuchid crocodyliform (Archosauria) from the Late Cretaceous of Patagonia (Argentina)

A new species of Baurusuchus (Crocodyliformes, Mesoeucrocodylia) from the Upper Cretaceous of Brazil, with the first complete postcranial skeleton described for the family Baurusuchidae

“…) in which Pabwehshi appears deeply nested within the Baurusuchidae. Two additional Upper Cretaceous South American terrestrial crocodiles, Cynodontosuchus rothi (Woodward, 1896) and Wargosuchus australis (Martinelli & Pais, 2008), were tentatively allocated in the Baurusuchidae by most authors (Price, 1959;Gasparini, 1981;Martinelli & Pais, 2008). However, their very fragmentary nature does not allow a more accurate evaluation of their phylogenetic position within the notosuchian radiation of South American mesoeucrocodylians.…”

First report of a derived abelisaurid theropod from the Bajo de la Carpa Formation (Late Cretaceous), Patagonia, Argentina

“…Among the diverse tetrapod fauna of this sedimentary unit, which includes abundant notosuchian mesoeucrocodylians and snakes (Woodward 1896(Woodward , 1901Martinelli 2003;Pol 2005;Martinelli & Pais 2008), five different small-sized theropod taxa have been described: the abelisauroid Velocisaurus unicus (Bonaparte 1991b), the alvarezsaurids Alvarezsaurus calvoi (Bonaparte 1991b) and Achillesaurus manazzonei (Martinelli & Vera 2007), the enantiornithean Neuquenornis volans (Chiappe & Calvo 1994), and the basal ornithuromorph Patagopteryx deferrariisi (Alvarenga & Bonaparte 1992). Nevertheless, it was not until recently that a medium-sized tetanuran theropod was reported from the Bajo de la Capra Formation, in beds corresponding to the Neuquén Province (Porfiri et al 2008).…”

Revisão da família Baurusuchidae e seu posicionamento filogenético dentro do clado Mesoeucrocodylia

“…Stratiotosuchus (Campos et al, 2001), Campinasuchus (Carvalho et al, 2011), Pissarrachampsa (Montefeltro et al, 2011) e Gondwanasuchus ; e o quinto gênero é argentino: Wargosuchus (Martinelli & Pais, 2008). Cada um destes táxons será descrito em detalhe nas sessões subsequentes do presente trabalho.…”
