> The theropod clade Carcharodontosauridae is a broadly distributed
> group of large allosauroid theropods. The carcharodontosaurids
> recorded in the Albian–Cenomanian of Gondwana are the youngest and
> most derived members of this clade. Tyrannotitan chubutensis, from the
> Cerro Castaño Member of Cerro Barcino Formation (Albian; Chubut
> Group), Central Patagonia, Argentina, is of prime interest among
> Gondwanan carcharodontosaurids as it represents the oldest record of
> the group. Here we offer a detailed osteological comparative
> description of the holotype and paratype of Tyrannotitan chubutensis
> together with a new diagnosis of the species. The new information
> results in a better understanding of this taxon and
> Carcharodontosauridae. Furthermore, a comparative study of the anatomy
> of the pectoral girdle of Giganotosaurus is reinterpreted as very
> similar to that of Tyrannotitan and Mapusaurus. We also present a
> phylogenetic analysis of Carcharodontosauridae that recovers
> Tyrannotitan as a derived carcharodontosaurid, being the sister group
> of the clade formed by Giganotosaurus and Mapusaurus, all nested in
> the clade Giganotosaurini.
