Through this immersive room, the visitor can enter a cave where the formation of Mexican territory over 165 million years ago is explained, with a particular focus on life that existed underwater in the Yucatán Peninsula, its transformation, and the paleoenvironment until the Ice Age (from 40,000 to 10,000 years ago). Highlights include life-size representations of Pleistocene fauna, such as mammoth tusks, the skull of a saber-toothed tiger, and the skeleton of a sloth—three of the thirteen species discovered in the Hoyo Negro cave in Tulum, Quintana Roo. The history narrated by Naia, the oldest woman in America, immerses visitors in the prehistoric world now submerged.
