Kʼan Ahk I,[1] also known as Ruler A was a king of the Mayan city of Piedras Nigras. He is also known as Turtleshell.[2]
He reigned c. 460. It seems that he was captured.[3]
His name combines the distinctive knotted headdress of God N with that aged earth deity's turtle shell and kʼan ("yellow/precious") marking; altogether it is probably read as itzamkʼanahk.[4]
