Charnel houses have been found in the larger villages. Black bear masks have been found in some graves, showing a possible indication of a rank. Of the average adult burials, it is not clearly understood where they might have been buried. To distinguish the characteristics between Fort Ancient and interior Monongahelan of West Virginia, Dr. McMichael writes, "A reflection of the Monongahela's greater Woodland heritage was the continued use of small stone mounds in the Monongahela drainage area, well into the Late Prehistoric." Child burials were sometimes inside the village and sometimes under the house. This contrasted with Andaste (Susquehannock) burials from 1450/1550, which were outside the palisaded village, as found east of the Allegheny Mountains.
