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.[1] 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.

gollark: So, *vaguely* like the Lost Cities moð?
gollark: PotatOS a virus? Nonsense.
gollark: <@!202992030685724675> If it would apparently be easy for me to, you should fix my plot's fusion reactor and stuff.
gollark: Just fix the reactory bit.
gollark: It was definitely possible, by figuring out how big each plot was and where 1;0;0 was.
