a Results of the 2D microwear analysis and (b) 3D microwear analysis (DMTA). In the case of the latter the PCA diagram based on the following variables: Asfc (complexity), epLsar (anisotropy), HAsfc (heterogeneity of area-scale fractal complexity), Smc (scale of maximum complexity). c Biplot showing anisotropy (epLsar) and complexity (Asfc). d results of the 2D microwear analysis based on placodonts and extant marine mammals
