Piedras Negras Ruler C
Piedras Negras Ruler C was a king of the Maya city-state of Piedras Negras. He was the successor of Turtle Tooth, who could be his father.
He is depicted on Panel 12. In the figural scene, Ruler C stands over three kneeling captives, one of whom is Knot-eye Jaguar I of Yaxchilan, who had captured a vassal of Turtle Tooth around 508. Another of the Panel 12 captives is from Santa Elena.
His successor was K'inich [Yo'nal Ahk I]. It is unknown if he was a son of Ruler C.
