Dental tissue proportions and enamel thickness in Rangifer tarandus: testing the potential of intra-tooth measurements for identifying subspecies
The remains found in a large number of archaeological sites attest to the essential role that the reindeer (Rangifer tarandus) had in the economic system of European hunter-gatherer societies during several periods of the Palaeolithic. When examining present-day Rangifer populations, a great deal of...

The remains found in a large number of archaeological sites attest to the essential role that the reindeer (Rangifer tarandus) had in the economic system of European hunter-gatherer societies during several periods of the Palaeolithic. When examining present-day Rangifer populations, a great deal of variability between different subspecies can be observed in terms of ecology, genetics, behaviour and morphology. However, very little information is known to date about the past ecological plasticity of this species, and how its ethological traits might have influenced the hunting dynamics of prehistoric human groups.Within the framework of the DeerPal project, we have attempted to access this information by studying the internal tooth morphology. Indeed, the study of the of dental tissues proportions and enamel thickness has already provided numerous results allowing the study of taxonomy and phylogenetic relationships, and a better understanding of adaptive strategies in extinct and present-day primates. However, to our knowledge, these parameters are little or not studied in other taxa. In this work, we have, for the first time, explored the information contained within the molars of two present-day Rangifer populations, one from Canada and the other from Norway, by studying the proportions of dental tissues in two (2D) and three (3D) dimensions.
