Figure 7. A, detail of the microwear pattern on the apical wear facet of the maxillary tooth MCF-PVPH-744 of Ligabuesaurus leanzai. Most of the pits and coarse grooves are evident with a binocular microscope (α) on the dentine exposed surface, whereas the scanning electron photomicrographs (β, γ, δ and ε) show abundant fine scars in both the enamel and dentine surfaces. Abbreviations: g, coarse groove; p, pit; s, fine scar.
