Three anatomical bony landmarks- Nasion (Na), Condylon (Cy) and Gonion (Go) were selected and two anthropometric measurements (Na-Cy and Na-Go) taken with the mouth closed (in centric relation (CR) position of the temporomandibular joints) and wide open with the help of the sliding caliper and the subject sitting on the chair in relaxed state and head in the anatomical position
2) Another case was discovered during a reanalysis of human bones excavated from a megalithic tomb at Millin Bay in County Down in 1953, which consisted of an adult male mandible with clear cut marks across the right ramus and gonion (Murphy 2003).

The Jaffes also claim an unspecified ownership stake in the famed Gonion Collection of glass-plate negatives, which has drawn many competing claims.
Encontraron que todos los puntos presentan similar reproducibilidad en las dos radiografias, excepto infraorbitario, espina nasal posterior, articular, porion y basion con menor error interobservador en la imagen digital directa; en otro estudio, Sandler reporto que los puntos articular y gonion son mas reproducibles con el trazo manual.
