 Much of the public imagery of the site details the ruthless manner in which the city dealt with its enemies . A 16 by 4 metres ( 52 by 13 ft ) stucco sculpture rising from the fourth to fifth terraces depicts a skeletal death god carrying the severed head of a lord of Palenque in one hand . A frieze on the fifth terrace probably displayed Toniná 's most distinguished victims , dozens of fragments of this frieze were discovered in the plaza below . This frieze was carved from the local sandstone but its style is that of Palenque , suggesting that captured artists carried out the work .
