The Chinchorro mummies of Chile are the oldest ever found, the oldest being over 9000 years old. Many of them are children, but some are so small archaeologists aren't sure if they are dolls, or statuettes, or if in fact they are real mummified babies. Tiffany and Ken travel to Africa in Chile where the mummies are conserved to test whether these are real mummified. Between 1100 and 1400 AD, Armatambo was one of the most important centers of the Peruvian Ichma culture. Where the rich city once stood is now the poor district of Virgen del Morro on the outskirts of Lima. Archaeologists have dug up around 200 mummies there. Now one of them is to be "unwrapped". And in our second investigation, a 3,500-year-old cemetery was discovered in Granada, southern Spain. But are the mummies lying there that old?
