Archaeologists in Mexico have been showing off discoveries unearthed during their aquatic expeditions into the world’s largest underwater cave.
Researchers from the Gran Acuifero Maya (GAM) exploration and preservation group presented ancient relics recovered from the site on Monday, including fossils of a type of ancient elephant, giant sloths and a shrine to a Mayan god. It’s believed that desperate animals ventured into the caves in search of water at times of severe drought, some of which then became trapped.
