A carbon and nitrogen isotopic investigation of a case of probable infantile scurvy (6th–4th centuries BC, Slovenia)

•Combined osteological and high resolution isotope data has been used to interpret an individual's life history.•The infant presented skeletal lesions consistent with chronic malnutrition, probably scurvy.•High δ13C and δ15N values that do not support a simple dietary interpretation.•Isotopic data is complex and should not be interpreted in isolation.
