The boys go back in time to the Cretaceous period of the Mesozoic era and get a Quetzalcoatlus (Harold calls it "Crackers", but George states there's no time to call it a name).
Each episode contains several missions that allows the player to either hunt or trap eight dinosaur species and one pterosaur:(Tyrannosaurus, Utahraptor, Troodon, Gastonia, Triceratops, Styracosaurus, Iguanodon, Lambeosaurus and Quetzalcoatlus).
Along the way, he uses a Quetzalcoatlus to evict the Sleg from the jungle and destroy their air ship.
The clade Chaoyangopteridae was first defined in 2008 by Lü Junchang and David Unwin as: "Chaoyangopterus, Shenzhoupterus, their most recent common ancestor and all taxa more closely related to this clade than to Tapejara, Tupuxuara or Quetzalcoatlus".
