Saving the Sabretooth
The Bug House
Brachiosaurus made their first appearance in the opening then in the third episode of Prehistoric Park, along with Microraptor. Despite not being anticipated arrivals, the Titanosaurs turned up as one of the more major creatures in the Prehistoric Park series. Not long after their capture in Episode 3 the Brachiosaurus and Diplodocus broke out of their paddock and continued to roam freely around the park. The Brachiosaurus and Diplodocus were quite a large problem to the park because of their large appetite and their destruction in their areas of the park. Some of the problems were that the herd knocked down trees and delayed the construction of The Bug House. During the next episode of Prehistoric Park a frightened Brachiosaurus rampaged through the park, resulting in the Mass Break-Out.
Nigel caught 20 Microraptors and puts them in cages and Nigel catches another Microraptor, but the volcano eruppts and a Brachiosaurus becomes panicked and almost crushed the captured microraptor and Nigel rescues it, but its wing is injured. Nigel and his crew carry the Microraptors and head to the beach and see a herd of Brachiosaurus and Diplodocus. The carbon dioxide gets higher. The dinosaurs start to rampage towards Nigel. Nigel and his crew wore gas masks and opened the portal. They carry the Microraptors and the Brachiosaurus family follow Nigel and his crew. Everyone made it to the 21st century and the Brachiosaurus caused the 1st damage in the 21st century. Bob puts them in pens, but they all the Brachiosaurs break through and then these creature will cause alot of trouble.
In episode 5, Nigel ties the jeep rope on a Brachiosaur's tail and brings the jeep with the 3 giant invertebrates. And Bob rewards the Brachiosaurus and Diplodocus a rock, just the way to say "ROOOOOOOAAAAAAAR!!!" In the next episode, Bob borrows the Jeep to clean up after Nigel brought back the Deinosuchus, and went near 10000 Diplodocus and Brachiosaurus, who were feeding. However, Rascal the Troodon became a stowaway and attacks Bob and the jeep scares a Titanosaur. Bob and the Troodon got out of the jeep after the Titanosaur panicked. The Titanosaur realased the Ornithomimus flock, frees the Terror Bird, frees the Woolly Rhino, and unleashes Big Al the Allosaurus.
Aside from being continually identified as titanosaur sauropods, the exact species of the dinosaurs was never revealed in the series. Fan speculation has put forth several identifications for the Diplodocus and Brachiosaurus, namely Borealosaurus, Daxiatitan, and Ruyangosaurus. Out of them all, Borealosaurus is probably the most likely candidate, as it lived at the right time period and its fossils have been found in Liaoning Province, where Episodes 123456 was set.
