A new hieroglyphic stairway has been found at El Palmar, Campeche, Mexico, during investigations by archaeologists Kenichiro Tsukamoto (University of Arizona) and Javier Lopez-Camacho (INAH). It is Late Classic in date and its text looks to be long and interesting.
More details can be found at the National Geographic news article posted on April 25.
It seems that recently excavated inscription form El Palmar mentions the same character as on Chakchoben stela: u-BAAH 13-CHAN-na KUY?-NAL PIK? SAK-o-ka 6-PIHT?-AJAW
Are the drawings available online?
Sorry to take a while to respond (I was in Yucatan). No, no drawings of El Palmar’s HS are available yet, since these things obviously take time. The El Palmar project will be publishing their images and results at some point, no doubt.
