Group Q5-2 features a large block of cut limestone that may have functioned as the base for a stela. The group is also notable for a small cave underneath the principal structure. Near the cave entrance was found a large shell that had been cut in half lengthwise in order to serve as a scribe's inkwell, as illustrated in Maya art. Because of this inkwell, the excavators have interpreted this group as the residence of a scribe. The group has been dated to the Late Classic.
