Fig. 6: Examples of non-masticatory labial striations [photos, Alicona Infinite Focus (AIF) 3D reconstruction, and 3D profiles].
From: Non-masticatory striations on human teeth from the British Upper Palaeolithic to the Neolithic
(a) Labial striations on an upper first incisor from Gough’s Cave (NHMUK PV M 54132) with [a1] showing an AIF 3D reconstruction (objective: 20x) and [a2] showing a reconstructed 3D profile used for measurements. (b) Labial striations on a lower second incisor from Abingdon (NHMUK PA SK 1788), with [b1] showing an AIF 3D reconstruction (objective: 50x) and [b2] showing a reconstructed 3D profile used for measurements. Thick red lines show the locations of measured profiles. Photo © Longleat Estate and Trustees of the Natural History Museum.
