Rondelles are thin, circular disc cut-outs typically made from the blade of the scapula of medium sized ungulates, such as horse or cervid. These are primarily associated with the Late Upper Palaeolithic Magdalenian and focused around northwest Europe. Rondelles are frequently perforated, with 2 mm - 3 mm diameter holes being common. There are many questions as to the production and use of rondelles. In this article, we discuss experiments on the making of both bone and slate rondelles and their usage.
