The “Time-Traveling Room” takes you to a time-travel in ancient world of Kitakyushu. Going up the slope in the cave, you will find the Early Cretaceous lake, where fishes restored by CG are swimming. Further steps make you find an Iganadon nest and its eggs and many insects living in the forest. At the end of the long cave slope, you reach to the large diorama hall surrounded by dinosaurs like a huge Mamenchisaurus and Dilong, plants and small animals of the Cretaceous Kitakyushu. A short drama shows a day from evening to dawn or extinction by eruptions.

Recreation of a Cretaceous Lake	Limestone Formations	Insect Trapped in Amber	Iguanodon Nest

These are computer-generated images of fish that swam in a giant lake in the Kitakyushu area during the Early Cretaceous Era (about 120 million years ago). Fishes, computer graphics >>	Before the Cretaceous Era, the rock mounds of Hiraodai Plateau are thought to have been sharp-edged, like the pillars of Akiyoshidai Plateau. Metamorphism by granite magma transformed the rock mounds into the limestones making their current shapes, which are said to resemble flocking sheep.	Amber, fossilized “resin”, sometimes hold insects and other small animals. Such specimens are very well preserved and show a great deal of detail. The insect trapped in this piece of Baltic amber is a fungus gnat (Mycetophilidae), and is about 40 million years old.	Dinosaurs lay eggs. Iguanodons warm eggs by the heat of decaying fern leaves.

Mamenchisaurus	Velociraptor	Dilong	Dictyozamites

The long neck of Mamenchisaurus is very useful for reaching distant plants for browsing.	Velociraptor is a small carnivorous dinosaur. It attacks other dinosaurs quickly.	Dilong id feathered dinosaur and belongs to basal Tyrannosauroidea.	Similar to cycads, Dictyozamites were gymnospermae that grew in the Mesozoic Era. Herbivorous dinosaurs probably ate this plant.
