The chapter discusses the comparison of the Acsádi-Nemeskéri and Suchey-Brooks methods for determining skeletal age based on the pubic bone. The authors, S. Brooks from the University of Nevada, Las Vegas, and J.M. Suchey from California State University, Fullerton, review various systems of age determination and focus on an extensive autopsy sample (n=1225) of pubic bones from modern individuals with documented age at death. The Suchey-Brooks method, derived from this sample, is described, while the Acsádi-Nemeskéri system is evaluated for its limitations, particularly in capturing intermediate stages of pubic bone development. The Suchey-Brooks method is then discussed as a more reliable alternative. The introduction provides historical context, highlighting key contributions from anatomists like Todd, Cobb, Brooks, and others, and the challenges in linking age changes with chronological age. The collection and preparation of the Suchey-Brooks sample are detailed, emphasizing the conservative approach to ensure the quality of the specimens.The chapter discusses the comparison of the Acsádi-Nemeskéri and Suchey-Brooks methods for determining skeletal age based on the pubic bone.
