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.
