The Campo Viejo platform and a monolithic sculpture found at the site have been dated to the Early Classic period, between A.D. 200 and 600.
Notes on verification
Multiple independent outlets (AFP-sourced reports, The Debrief, La Brujula Verde) corroborate the dating of the Campo Viejo platform and monolith to the Early Classic period, consistent with original INAH findings.
