Survivorship profile based on percentage of fused long bones, for Polderweg Period 1 (n = 227), De Bruin Period 1 (n = 32), De Bruin Period 2 (n = 51), and De Bruin Period 4 (n = 22).
Polderweg Period 2 and 3 had too few specimens to calculate the survivorship score. Survivorship percentage calculated following Zeder et al. 2015.
