Sue Black is a forensic anthropologist and anatomist who studies human remains to determine a person’s identification and cause of death. Written in Bone works its way down the human skeleton, starting at the skull, detailing the kinds of information our bones contain—approximate age, sex, height, weight—even when that’s all that’s left. She includes anecdotes from her work in the field, relaying confounding cases where her knowledge of human development was vital. Did you know babies are born with, like, a zillion bones that fuse together to form a proper skeleton as they age? SO. COOL.
