There're huge dinosaurs in the forest north of the Veldt. They're incredibly strong.
Dinosaur forest is a term used to describe a location in Final Fantasy VI. It is a forest located north of the Veldt in the World of Ruin, and is roughly in the shape of a dinosaur's head. The forest is well known for being the home of the Tyrannosaur and Brachiosaur, two of the best monsters in the game for leveling up.
Brachiosaurs also have Ribbons to steal and can drop Celestriads, two of the best Relics. However, the two enemies are very powerful and can easily kill the party if the player is unprepared. The enemies on the plains outside the forest also leave a lot of experience points and are easier to kill if the player is having trouble with the Tyrannosaurs.
Dinosaurs are a diverse group of animals of the clade Dinosauria. They first appeared during the Triassic period, 231.4 million years ago, and were the dominant terrestrial vertebrates for 135 million years, from the start of the Jurassic (about 200 million years ago) until the end of the Cretaceous (66 million years ago), when the Cretaceous–Paleogene extinction event led to the extinction of most dinosaur groups at the end of the Mesozoic Era.
