Iowa archaeology, ossuary, Late Archaic, paleopathology
This Late Archaic ossuary, approximately 2800 years old, was discovered near Council Bluffs, Iowa in 1975 during earth moving operations that partially destroyed it. The fragile skeletal remains of 25 individuals ranging from childhood to old age were recovered from the undisturbed portion. Slight to moderate arthritic changes were observed in 4 of the 18 adult skeletons and one example of spondylolysis was encountered. There was no unequivocal evidence of dental caries. Abrasion of the teeth was severe, starting soon after the teeth erupted, and progressing to serious dental complications in one-third of the adults over 20 years of age. A similar number of adults were afflicted with periodontal disease. Two teeth of a child between 1 and 2 years of age showed pigmentation suggestive of erythroblastosis fetalis.
