Dental Microwear Texture Analysis (DMTA) of tooth surfaces of fossil wolves from Britain

One Excel workbook reporting dental microwear texture analysis (DMTA) raw data. These are values from scale-sensitive fractal analysis (SSFA), and areal surface texture analysis (based on a suite of parameters, most of which are defined by ISO-25718-2) for dental microwear texture analysis of tooth surfaces of wolves from Britain (MIS 2, MIS 3, MIS 5a). This study examines the dietary adaptability of European grey wolves using dental microwear texture analysis (DMTA). These datasets offer new insights into the palaeoclimatic and palaeoenvironmental conditions under which grey wolves endured climate change in the past, free of anthropogenic influence. Tooth surface casts were produced using high-resolution, which is optimised for imaging purposes. Epoxy tooth replicas were scanned with a Sensofar S neox. MountainsMap Imaging Topography was utilised to quantify dental microwear texture parameters from Sensofar scans.

Statement: Epoxy tooth replicas were scanned with a Sensofar S neox. MountainsMap Imaging Topography (version V10, Digital Surf, Besançon, France) was utilised to quantify dental microwear texture parameters. Scan processing protocol: 1) levelling with least squares plane (LSPL) to correct surface inclination, 2) threshold application to eliminate the upper and lower 0.1% of data, 3) filling of non-measured point using the smooth shape calculated from neighbours function, 4) surface point retouching to manually edit dust and extraneous particles followed by filling of missing data points using the smooth shape calculated from neighbours function, 5) level again for generating SSFA parameters, 6) form removal with polynomial of degree – 2 (7) spatial filtering (robust Gaussian, order 0 (ISO 16610-71); with a cut-off value of 0.025 ?m) for generating ISO parameters.
