In this room we find representations of the daily life of humans and animal species that inhabited the Earth millions of years ago. Dioramas start in the Mesozoic era (the time of the dinosaurs) and last until prehistory, a period in the history of humankind that ranges from the origin of man to the appearance of the first written testimonies.

Representations such as a marine combat in the Jurassic period or the fight between a tyrannosaurus and a triceratops during the Cretaceous period, the dioramas include less distant scenes, such as the Magdalenian period, the last great Palaeolithic culture of Western Europe.

It is at this time that prehistoric artists were consecrated, making the richest prehistoric paintings. The most outstanding diorama is inspired by the cave paintings of the Spanish Levant, which represent the first inhabitants of the territories of the Valencian Community.
