Known as Lady Snake Lord to her pals and Kaloomte, or "supreme warrior" to her subjects, Lady K'abel ruled the Wak kingdom in present day Guatemala between AD 672 and 692.
Archaeologists from the Washington University in Missouri have found what they believe to be her burial site inside the main pyramid temple of the ancient city of El Peru-Waka.
Other items found in the ruins include ceramic jars, jewellery made from Jade and red spiny oyster "girdle ornaments".
