In this study, we present the results of archaeomagnetic dating analysis of a burned floor from the fifth and last construction stage of the Ocomo Palace archaeological site, Jalisco, Mexico. The lack of a date for the age of the abandonment of the site motivated us to apply archaeomagnetism, an alternative method of dating, independent of the traditional procedures. The results indicate that the most likely date for the last exposure to fire of the analyzed floor is the interval of 759–915 cal AD (95% probability), which is quite consistent with the available archaeological evidence for the Ocomo Palace site, and which restricts the wide chronology of this site to the Epiclassic period.
