Max Length =  maximum bone length in cms; underlined superscripts a and b indicate significantly higher %DA in Iron Age females relative to the Bronze Age (a: p<0.034; b: p<0.038); underlined superscript c indicates significantly higher %DA in Iron Age males relative to Neolithic (p<0.006) and Bronze Age (p<0.004) males; bold indicates significant sexual dimorphism (TA and J: p<0.001 for both; max length: Neolithic p<0.011; Bronze Age p<0.001).
