When did the giganotosaurus live?

Giganotosaurus lived 97 million years ago in what is now Argentina. At the time the area had braided river system, and the local plants would have included conifers, cycads, ferns, horsetails, ginkgoes, and a few very primitive flowering plants. Other dinosaurs that shared this habitat include the sauropods (giant, long necked herbivores) Limaysaurus, Nopcsaspondylus, and Andesaurus, and these may have been prey animals for Giganotosaurus. There were also iguanodonts, relatives of Iguanodon, that definitely would have been prey for the Giganotosaurus. Other predatory dinosaurs that lived here include Ekrixinatosaurus, a 33 to 36 foot long abelisaur, Buitreraptor, a rooster sized dromaeosaur, Bicentenaria, an 8 to 10 foot long carnivore, and Alnashetri.
