Traditional accounts of animals in Mesolithic Northwest Europe have ultimately been economic in character, with a particular focus of the larger ungulate species that formed the dietary mainstay. Smaller mammalian species, regularly grouped as ‘fur-bearing’ species, also play a role in such accounts, as the source of important non-nutritional materials, namely their fur. However, how has placing these species in this broad category impacted archaeology's interpretation of their remains in the Mesolithic? This paper argues economic categorization of these species has led to an automatic interpretation of their remains, which may overlook evidence for other uses and treatments. This research proposes that the remains of ‘fur-bearing’ species were not just waste products from fur extraction, but were also wrapped up in complex and meaningful human-nonhuman relationships, which impacted how these remains were treated, and ultimately shaped the archaeological record.
