1. Holwerda mentions that an oval discolouration was visible, surrounded by a burnt line, as if a wooden fence were burnt there. He does not specifically mention that charcoal was present, though this was probably the case.
2. The Dienst Specialistische Recherche Toepassingen of the Korps Landelijke Politiediensten (KLPD).
3. The exact location of the barrow is unknown, Holwerda did not provide a map with his article. The ROB in 1984 reconstructed several barrows at Niersen from old spoil-heaps of the excavation. The barrow they identified as G4 is located at x: 191108 and y: 478789 in the Dutch co-ordinate system. There is however no direct evidence that this was indeed barrow G4.

5. Louwe Kooijmans (1974, p.311, note 246) already observed that Holwerda made a mistake in the drawing of his excavation plan. The crouched inhumation should be at the south side of the pit with the disarticulated deposition at its back at the north side. This can be clearly seen in photograph Pl.I, 3 showing the bones in situ and can also be inferred from the skeletal remains in the museum. The skeletons are mirrored in the small plan of the barrow, but they are each mirrored individually and not the grave as a whole.
6. The measurements are on the basis of the length of the crouched inhumation, which from the top of the skull to the bottom of the pelvis is approximately 1m long. The scale obtained this way is in agreement with the 10 m diameter of the palisaded ditch encircling the barrow.
7. Generally dated between 2900 and 2000 cal.BC (van den Broeke et al. 2005, 28)
