Ancient rock paintings, believed to be between 2,000 and 3,000 years old, have been discovered in a cave in Brazil's Itatiaia National Park. Experts are studying the paintings to determine their age, origin, and cultural significance. The site has been fenced off and public access is temporarily prohibited to protect the archaeological discovery. The paintings feature geometric and animal designs and may be related to other archaeological sites in the region. The discovery of these paintings is unprecedented in the state of Rio de Janeiro and may become a tourist attraction in the future.
