Burial 1 was found interred under the ledge joining the first and second levels of Pyramid B1-2. The burial consisted of a lower jaw and the remains of several other bones, accompanied by ceramic fragments and some obsidian artefacts. The dispersed remains indicate that Burial 1 was a secondary burial, possibly that of a human sacrifice associated with the dedication of the final phase of the pyramid. The teeth indicate that the remains were those of a young adult; the associated ceramics date the burial to the Terminal Classic or Early Postclassic.
