 An Early Classic tomb was inserted under the main pyramid at Zaculeu ; it had been tunnelled from the volcanic ash underlying the structure . A broad stairway descended to the tomb from the main plaza . The tomb interior was painted red and the floor was scattered with the remains of more than 100 ceramic vessels . These were crushed when the roof of the tomb collapsed . Also found were the remains of 34 pyrite mirrors of a type similar to those found at Kaminaljuyu . A sizeable quantity of jade was recovered from the tomb , including beads and earplugs . Some of the jade beads had been carved to represent human and parrot faces . The tomb contained the bones of four or more individuals . The ceramic offerings included decorated tripod vessels , polychrome bowls and a polychrome cylindrical vase that had a painted band of hieroglyphs . One ceramic bowl is painted in a negative painting style that is similar to finds from Nebaj .
