INAH scientists discovered the object carved in stone containing the text of a grapheme measuring just over 11 square meters, in the archaeological zone of Coba, in Quintana Roo, also known as Nohoch Mul.

INAH director Diego Prieto explained that the tablet consisted of 123 L-shaped hieroglyphic cartouches belonging to the Keh Witz Nal people.

Prieto stated that with these studies, they recognized the name of a sovereign, K’awiil Ch’ak Cheen, identified for the first time, thus managing to fill a gap in the dynastic sequence of Coba.
