Cleopatra's mother 'was African'
Queen Cleopatra was a descendant of Ptolemy, the Macedonian general who ruled Egypt after Alexander the Great.
But remains of the queen's sister Princess Arsinoe, found in Ephesus, Turkey, indicate that her mother had an "African" skeleton.
Experts have described the results as "a real sensation."
The discovery was made by Hilke Thuer of the Austrian Academy of Sciences.
"It is unique in the life of an archaeologist to find the tomb and the skeleton of a member of Ptolemaic dynasty," he said.
"That Arsinoe had an African mother is a real sensation which leads to a new insight on Cleopatra's family and the relationship of the sisters Cleopatra and Arsinoe."
