This study presents pathologies and abnormalities identified on the skeletal sample discovered in 2014, in the Aroneanu Monastery Necropolis of Iași (Iași County, Romania). According to the archaeological information, the necropolis was used during the 16th-19th centuries. The analyzed sample includes a total of 79 skeletons (originated from inhumation tombs and reburials), out of which 17 belonged to children (aged 0-14 years: 21.52%), two to adolescents (14-20 years: 2.53%), nine to adults (20-30 years: 11.39%), 47 to matures (30-60 years: 59.49%) and only four to elderly (60-x years: 5.06%). The preservation status of the skeletons is unsatisfactory. The distribution by sex indicates a higher male frequency (42 men and 20 women – with a masculinity index of 2.10). The average life span, both for the entire series (0-x years - 36.61 years), and by sex (20-x years – 47.38 years in the male group and 41.97 years in the female group) has similar values to those estimated for the late medieval populations who inhabited the Central Moldavian Plateau. The pathologies, abnormalities features were evaluated both separately by sex and for the entire sample. In the cranial segment (for the entire sample), wormian bones recorded the highest frequency, followed by the supragingival dental calculus, dental caries, radicular remains and metopic suture. Other pathologies and abnormalities (i.e. granuloma, edentia, hypodontia, cribra orbitalia and cranial trauma) were sporadic. In the postcranial segment, the most frequent pathology is the osteoarthritis, and as abnormalities we mention extra facets of the tibia, spina bifida occulta and sacralization. In the male series, the frequency of pathologies and abnormalities is higher compared to the female series. There are no pathologies and anomalies on the skeletons of children and adolescents.
