“…However, unlike microfaunal components, for which we have rich fossil data 18,49 51 , which are known from more complete skeletons, are more compelling, yet fewer in number. Although Siats fills a critical gap in the biogeographic history of Early to mid-Cretaceous theropods, the poor fossil record of the group globally 11,29,34,43,44 , various possible resolutions of Megaraptora in our analyses, and long ghost lineages subtended by most megaraptoran species continue to permit both global distribution and interchange biogeographic scenarios with equal likelihood. Increased resolution of neovenatorid relationships and increased sampling of Early Cretaceous theropods around the globe will be necessary to test ancestral geographic origins for Siats and other carcharodontosaurians.…”

“…To date, carcharodontosaurians are not known to have survived past the Turonian (B92 Ma) on Laurasian landmasses 11,30 and also decline in South America over the same timeframe 34,35 (Fig. 5a).…”

“…Este Subgrupo presenta dos formaciones: Bajo de la Carpa y Anacleto (ambas definidas por Herrero Ducloux en Fossa Mancini et al, 1938), compuestas por niveles donde predominan las arenas y las arcillas, respectivamente (Cazau & Ulliana, 1973). Dichos sedimentos se encuentran expuestos en el área comprendida entre la ciudad de Neuquén y la sierra de Portezuelo (provincia de Neuquén) y en la región de los alrededores de la planicie de Rentería (provincia de Río Negro) (Leanza et al, 2004). La edad de esta secuencia es considerada Santoniana -Campaniana temprana por Leanza (1999) y Hugo & Leanza (2001a, 2001b.…”

“…Nuevas exploraciones en la región, realizadas a partir del año 2003, permitieron redescubrir los niveles fosilíferos con restos de tetrápodos, que permitieron precisar datos sistemáticos (Apesteguía, 2004) y bioestratigráficos (Leanza et al, 2004), así como también iniciar estudios tafonómicos (Pérez et al, 2006).…”

“…2 The theropod record of the Upper Cretaceous Portezuelo Formation (Late Turonian-Early Coniacian; Leanza et al, 2004) currently consists of the abelisaurid Ekrixinatosaurus novasi (Calvo et al, 2004a), the basal tetanuran Megaraptor namunhuaiquii (Novas, 1998;Calvo et al, 2004b), the maniraptoran alvarezsaurid Patagonykus puertai (Novas, 1997), two yet undescribed coelurosaurians (Coria & Currie, 2002;Porfiri et al, 2005), and the dromaeosaurid maniraptorans Unenlagia comahuensis (Novas & Puerta, 1997), U. paynemili (Calvo et al, 2005), and Neuquenraptor argentinus (Novas & Pol, 2005). Here we describe a partial humerus that constitutes the first non-abelisaurid abelisauroid recorded in the Portezuelo Formation.…”
