Cretaceous

The Cretaceous was a period in Earth's history. This period is notable as non-avian dinosaurs went extinct at its end. During the Cretaceous, reptiles and dinosaurs occupied the highest ecological niches on the land, sea and skies.

T-Rex Returns
On his first expedition, Nigel Marven traveled to the end of the Cretaceous to rescue Tyrannosaurus rex from imminent extinction. On his journey in the Cretaceous, he brought a flock of Ornithomimus back to Prehistoric Park as well as an adolescent, male Triceratops. At the end of his journey, as the meteorite impact took place, he only just managed to save two orphaned juvenileTyrannosaurus rex from certain death.

Dinobirds
Nigel traveled to the Early Cretaceous to bring back the four-winged Microraptor. During his travels, he encountered the buck-toothed Incisivosaurus, a herd of giant titanosaurs, a flock of Microraptor, and a pack of Mei long. At the end of his expedition, as a volcano erupted, he saved the panicked herd of titanosaurs as well as several Microraptor.

Supercroc
On his penultimate expedition, Nigel traveled to the Late Cretaceous (75 mya) to try to save the 50-foot Deinosuchus from extinction. On his expedition, he encountered a herd of Parasaurolophus, the early cousin of Tyrannosaurus rex - Albertosaurus, a flock of Nyctosaurus and the cunning Troodon. At the end of the expedition in the Cretaceous, Nigel brought back a female Deinosuchus and a Troodon unintentionally.
