The Brontosaurus (ブロントサウルス Burontosaurusu) is a dinosaur from the Jurassic period. A mother and child Brontosaurus were one of the many poacher targets in Dinosaur Expedition Born Free.


Dinosaur Expedition Born Free

When poachers decided that the animals of modern day where too boring, they went back in time to hunt real game. Amongst their many targets was a massive brontosaur. The gentle giant was too big to hide and too slow to not chase. However, with the help of the Born Free gang, the Brontosaur was able to escape all these poacher traps and raise a child who became friends with the two youngest Born Free members.


  • The stop motion puppet for the brontosaur would be a common sight in Ururu's underground palace in Dinosaur Great War Izenborg.
  • When the Great Dinosaur War broke out, the Brontosaurus wasn't given a suit. It would only gain a suit in the Dinosaur Trilogy series' ending, Koseidon.


Powers and Weapons
  • Tail: Like all sauropods, the brontosaurus can use its massive tail as a weapon.
  • Size: In the laws of nature, when you're big, you don't need special defenses. The brontosaurus is a perfect example of this.
