Unmodified and modified animal remains and animal representations significantly contribute to the content of Mesolithic and, in some cases, Early Neolithic hunter-gatherer burial assemblages in Northern Europe. Though these finds have received noteworthy attention, predominant archaeological narratives focus on their economic, aesthetic, or symbolic values in relation to humans. This contribution explores ways of looking at these assemblages beyond seeing them primarily as signifiers of human identities and human symbolic and/or economic choices. Drawing on insights from Russian ethnographic literature about near-recent East Siberian hunting and gathering communities, this paper explores paths for understanding unmodified and modified animal remains and animal representations from Mesolithic and Neolithic hunter-gatherer graves as animate objects and investigates ways of recognising their personhood. The paper outlines what could be considered as the material consequences of communicative actions and performative acts in relation to artefacts and animal remains that might have been perceived as having the qualities of a person, such as their placement and arrangement within the burial and treatment prior to deposition.
