The roughly 2,000-year-old tomb was found underneath another, 1,300-year-old tomb filled with treasures such as jade gorgets - normally used to protect the throat - beads, and ceremonial knives.
The upper tomb's corpse had been badly destroyed by rodents within the last few centuries, but the body was clearly that of another Maya ruler - perhaps another female, based on the small size of a ring found in that tomb.
The royal burials are the first discovered in Nakum, once a densely packed Maya center. Study co-author Wiesław Koszkul and colleagues have been investigating Nakum's surroundings, known as the Cultural Triangle, for decades. (Explore an interactive map of key Maya sites.)

A woman ruler's skeleton—her head mysteriously placed between two bowls—is one of two royal burials recently found at the Maya ruins of Nakum in Guatemala.
The Maya royal-tomb discoveries are described in the September issue of the journal Antiquity.
