who may have ruled at Yoʼokop under the overlord Sky Witness from Calakmul or Dzoyola. The risers were not found in-situ. (For information on Sky Witness, see the work of Simon Martin and Nicolai Grube.) Prior to Shaw and Johnstone's project the site had been best-studied by Reginald Wilson, who published his findings during the 1970s. A brief visit to the site was also made during the 1950s by the Carnegie Institution of Washington. Scholarship Flores Colin, Alberto G., Dave Johnstone, Justine M.
