Several Estonian burial places with cremations were investigated in the period 1997 to 2011. During the research, various descriptive and metric data on cremated bone materials was observed. The present paper is an attempt to systematise and interpret the data collected, in order to provide some generalisations on Estonian cremations. A comparative study of graves on the basis of the minimum number of buried individuals and the number of determined bone finds in graves, as well as bone fragmentation, is presented. Radiocarbon dating (AMS method) of burnt human bones from six investigated graves was conducted in order to specify the usage time of the graves. Some conclusions on possible temporal changes and cultural differences in burial practices are made on the basis of these characteristics.
