Who killed the small mammals of Ittenheim? An integrative approach and new taphonomic data for investigating bone assemblages accumulated by small carnivores.

Résumé En

Small carnivores are susceptible to regularly accumulating small- to medium-sized mammal remains in both natural and archaeological sites. However, compared to nocturnal birds of prey, these accumulations are still poorly documented and are generally based on a limited number of samples, including those of relatively small size. Here, we present an analysis of European hamster remains from Ittenheim, which were recovered from an infilled burrow, 3m below the current surface. The remains are well preserved and exhibit large proportions of tooth marks. Comparisons with a new and existing reference collection combined with an analysis of all recovered faunal remains suggest the accumulation reflects the action of young red foxes. This is supported by the fact that, although these young individuals leave teeth mark, they do not necessarily consume all parts of medium-sized prey species, including the European hamster. Conversely, the remains of smaller rodents, such as microtine, show distinct patterns of digestion and tooth marks. Carnivore bone accumulations from scats are generally poorly preserved; however, our results demonstrate prey size plays a major role, both qualitatively and quantitatively, in skeletal representation, bone preservation, and bone surface modifications. The present paper underlines the need for more diversified taphonomic reference collections based on an integrative approach designed to evaluate multi-taxa accumulations.
