. Gigantosaurus: -

Isn’t the name gigantic in itself? It also meant the “giant southern lizard”. Discovered by an amateur fossil hunter namely, Ruben Dario Carolini, on 25th of July 1993 in deposits of Patagonia, this giant monster is argued to have resided in Argentina during the late cretaceous period. Belonging from the genus of carcharodontosaurid dinosaurs. This big boy had a length of skull almost comparable to that of a T-REX. They were carnivores by nature. In size, it was bigger than the Carcharodontosaurus but not as large as spinosautus.
