Dear colleagues,

Does anyone know of any early sources in which the survivorship for animals is calculated by the percent of fused epiphyses for different age classes? (For example, if group A (px. radius and ds. scapula) has 3 fused, 1 unfused remains, then the percent fused = 75%, and the survivorship of animals past group A is thus 75%).

The earliest source I can find for this is Flannery's 1969 chapter in the Prehistory and Human Ecology of the Deh Luran Plain.

Thanks in advance,
