Later Acheulian Marking Motifs I - Bilzingsleben, Germany / n)blzmf6
Object #4=182.32, a thin flat slice of bone, has 7 roughly parallel stroke marks at regular intervals of 3 mm., all uniform and engraved by the same tool and the first and fifth element more than twice as long as the others and composed of two lines crossing at an acute angle [Xs] (Mania and Mania 1988:fig 6; Bednarik 1995:fig. 1d). Steguweits (1999) laser analysis and microphoto rather indicate either 8 lines or 7 lines with the first unit being an X of two crossing lines; the fifth and sixth unit do not cross.
