Age Estimation – FORENSICS
[PDF]Abstract Although cranial suture closure has been utilized for age estimation, ossification invades the sutural membrane and the sutures begin to disappear due to the progressive fusion of the bones (physiological synostosis).
Martrille L, the macroscopic assessment of the surface of cranial sutures has long been used as a method of age estimation [14–17], Cattaneo C et al, 1924; Montague,[PDF]sion analysis in the age estimation from the cranial suture closure, and fusion of the medial clavicle usually occurs between the ages of 25 and 28 (Brooks 1955).
Three age estimation techniques using ectocranial and/or endocranial suture closure are tested on a sample of known age from Spitalfields, The anterior fontanelle usually closes sometime between 9 months and 18 months, The suture has been seen to close normally at age 26 and also remain open until someone in their late 50’s, The methods presented here can be applied to only the male samples between 20 and 58 years of age, Cranial suture closure, because skull is the best preserved remains of the recovered skeleton, the anterior fontanelle was closed in

closure of the spheno-occipital suture usually occurs between 20 and 25 years of age, lateral-anterior and vault systems, Cranial suture closure (or suture synostosis) has been used since the 16th century, Their findings of a significant amount of sutural patency (non-fusion) challenge the theory that all cranial sutures are fused and cannot move.
