Prehistoric Mammals provides a multifaceted introduction to mammals that lived in Japan approximately 10,000 to 120 million years ago, now extinct and therefore no longer observable.
Mammalian evolution and extinction is a cycle that has been going on for more than 100 million years. In addition to adaptation and evolution in the animals themselves, geographical changes and global changes in climate are also thought to have had a major impact on that history.
Prehistoric Mammals portrays such changes in the natural environment and provides an easily understood introduction to mammalian evolution and extinction based on major fossil specimens of prehistoric mammals discovered in Japan.
This special exhibit includes approximately 170 valuable specimens, such as the three fully reconstructed Palaeoloxodon naumanni skeletons presented as a “family” of male, female and child, and a Paleoparadoxia fossil discovered in Japan and now world famous.
Never before has an exhibition of such scale and depth featuring Japan’s prehistoric mammals been presented anywhere in the world.
