4 Mesozoic Hall

The Paleozoic era is followed by 200 million years of the Mesozoic era, which is characterized by relatively mild climate. Dinosaurs saw their climax, and died out.

Angiosperms and early mammals in the late Mesozoic, are closely related to their modern species.

Visitors in this hall would first meet the full-scale skeletal replicas of a carnivorous dinosaur, Allosaurus, a herbivorous dinosaur, Yuanmousaurus and Stegosaurus and a sea-living large reptile, Dolichorhynchops. Various fossils and the diorama would help further understanding of the era.

5 Edmontosaurus Hall

With courtesy of the Denver Museum of Natural History, the city of Toyohashi acquired a full-scale skeleton fossil of Edmontosaurus annectens. Beside this 90%-genuine model, a touchable replica of its skull, and a video show of its excavation give further information on this dinosaur.

6 Cenozoic Hall

It was 65 million years ago when dinosaurs and ammonites became extinct. In the following Cenozoic era, mammalia evolved. A diversity of mammals dominated the earth in the late Cenozoic era, when the cold and warm climates recurred.

The Cenozoic Hall offers the dioramas of the Paleoparadoxia at the seashore and the elephant hunting in the Quaternary. The skeletal replicas here include the one of a Naumann's elephant, Palaeoloxodon naumanni, an ancient deer, Sinomegaceros yabei, and an ancient reptile, Toyotamaphimeia machikanensis. All the three were excavated in Japan. There are also a full-size skeletal fossil of an ancient bear, Ursus spelaeus and of a sea-living Minke whale, Balaenoptera acutorostrata. The replicas of molar tooth of ancient elephant, and of skull and forefoot of an ancient horse, and reconstruction models and replicas of human skulls focus on the evolution of individual species.
