Balkaya et al. (2023:411–413) identified a discontinuity in the form of a fissure described as "a 5–6 cm wide fissure with 15–18 cm of vertical motion along the south block". Three radiocarbon samples were taken from the infill within the fissure, the unit covering the infill, and the unit cut by the fissure. These were modeled in OxCal and produced an age estimate for the event of 3400–3340 BCE, which the authors approximated to "around 3400 BCE".
