Giganotosaurus

Giganotosaurus (meaning "giant southern lizard") is an extinct genus of Carcharodontosaurid theropod dinosaurs that lived in the Cenomanian of Argentina 99.6 - 97 mya. The holotype was discovered in the Candeleros Formation of Patagonia in 1993, and is about 70% complete. The animal was named Giganotosaurus carolinii in 1995; the genus name translates as "giant southern lizard" and the specific name honors the discoverer, Rubén D. Carolini. A dentary bone, a tooth and some tracks, discovered before the holotype, were later assigned to this animal. The genus attracted much interest and became part of a scientific debate about the maximum sizes of theropod dinosaurs.
