  1. The amount of collagen extracted (%Coll) and C:N ratios refer to the > 30 kDa fraction. The ages are rounded to the nearest 10 years.
  2. Elements found in 2014 are attributed to the L2B-L2Bj complex because it was not possible to directly relate the excavated area (at the same elevation but located to the West or to the East) to the layers excavated in 1970.
  3. Ages have been calibrated using OxCal 4.4 61 using the international calibration curve IntCal 20 62.
  4. AC = associated to the child (LF8), those elements come from the bag filled in 1970 with the objects founds in the layer M2 in the eastern part of square 1 (in green on Fig. 1) and from the box filled in 1973 during the excavation of the hominin remains in the western part of square 1 (in red on Fig. 1).
  5. aMay extend out of range, but this bone is located to the east of the area where LF8 was found. We cannot ascertain its provenience from the L2Bj layer that was located above the archeo-paleontological layer that contained the child.
  6. bIdentified by ZooMS as a human remain, and as a Neandertal using mitochondrial DNA.
  7. cThis bone was collected in 1970 while the area was excavated more rapidly than in 1973. Its deamidation value is different from the other elements analysed by ZooMS (Supplementary Fig. S15), indicating a potentially different post-mortem history.
