Professor Golden and his colleagues published their discovery in the Journal of Field Archaeology.
The paper is titled Centering the Classic Maya Kingdom of Sak Tz’i’.

“Although no complete map exists for any of the previously known capital centres of the Lacanjá River valley, the site is comparable to, and likely more expansive than, Bonampak, Lacanha, and Plan de Ayutla.”
