Dinosaur size
There were larger dinosaurs, but knowledge of them is based entirely on a small number of fragmentary fossils. Most of the largest herbivorous specimens on record were discovered in the 1970s or later, and include the massive titanosaur "Argentinosaurus huinculensis", which is the largest dinosaur known from uncontroversial evidence, estimated to have been and long. Some of the longest sauropods were those with exceptionally long, whip-like tails, such as the "Diplodocus hallorum" (formerly "Seismosaurus") and the 33- to 35-metre-long (108–115 ft) "Supersaurus". The tallest was the "Brachiosaurus".
Carcharodontosaurinae
Carcharodontosaurinae (from the Greek καρχαροδοντόσαυρος, "carcharodontósauros": "jagged-toothed lizards") was group of theropod dinosaurs known from the Aptian to the Cenomanian/Turonian of Africa and South America. The clade was first named in 2007 by Steve Brusatte and Paul Sereno. The subfamily consists of gigantic derived carcharodontosaurids, among the largest theropod dinosaurs known, comparable in size to "Tyrannosaurus". Carcharodontosaurinae is defined as the least inclusive clade containing "Carcharodontosaurus" and "Giganotosaurus". Within this subfamily is the tribe Giganotosaurini. This tribe was originally its own subfamily, Giganotosaurinae, which was erected by Rodolfo Coria and Philip J. Currie in 2006. In order to keep this clade within the subfamily Carcharodontosaurinae, Brusatte and Sereno renamed and reranked it as a tribe. Giganotosaurini is defined as all carcharodontosaurines that are closer to "Giganotosaurus" than to "Carcharodontosaurus".
