or 909, probably the latter.Stela 62 was unfinished. It was carved to mark the K'atun-ending ceremony of 751 and bears the damaged name of Ruler Z.Stela 76 and Stela 78 are a pair of monuments dated to AD 633. They are badly eroded but should date to the reign of king Yuknoom Head.Stela 84 is one of the last monuments erected at Calakmul and bears an inscription that is an illiterate imitation of writing. It probably dates to the early 10th century AD.Stela 88 may have been paired with Stela 62. The monument has the image of a queen but her name is unknown. B'olon K'awiil also appears to be mentioned on the stela. It dates to around 751 and stands on the stairway of Structure 13. Stela 91 is another very late monument probably dating to the early 10th century. Like Stela 84, it bears an inscription that is a meaningless imitation of hieroglyphic writing.Stela 114 dates to AD 435, in the Early Classic. It was moved in antiquity to be reset into the base of Structure 2. The stela has a long hieroglyphic text that has resisted translation but probably commemorates a royal enthronement in 411.Stela 115 and Stela 116 date to the reign of Yuknoom Yich'aak K'ak'. They were broken and buried in Structure 2 and may be associated with the royal burial in Tomb 4. Royal burialTomb 4''' was set into the floor of Structure 2B in the 8th century AD and is the richest burial known from Calakmul. The tomb contained a male skeleton wrapped in textiles and jaguar pelts that were partially preserved with resin. The tomb contained rich offerings that included jade ear ornaments handed down from the Early Classic, a jade mosaic mask, shell and bone beads, spiny oyster shells, eccentric obsidian blades, fine ceramics and the remains of wooden objects. One of the ceramics was a plate with a hieroglyphic text that specifically named king Yuknoom Yich'aak K'ak' as its owner. The remains and the offering were placed in an arched wooden bier carved with elaborate decoration and hieroglyphs that was painted in a variety of colours. The bier has almost completely decayed but left an impression in the mud packed around it. Due to the plate and the possible association of Stelae 115 and 116 with the burial the tomb is believed to be that of the late 7th-century king
