Challenges of Human Skeletal Remains
The study and care of human skeletal remains continues to provide challenges to archaeologists and conservators, as the cultural implications of the remains often supersede their scientific implications. Many of the cultural and legal aspects of working with skeletal remains, however, can be mitigated if archaeologists and conservators remain vigilant about treating the remains of the individuals and their potential ancestors with the proper respect. While certain laws, such as the Native American Graves Protection and Repatriation Act (NAGPRA), exist to prevent the study of remains in deference to religious and cultural beliefs, they do not broadly hinder the study of human remains, as there continue to be many other remains to be examined. Conservators working with human remains should both be knowledgeable about conservation of bones and be concerned with the remains as a person.
Though the conservation of skeletal remains often lies outside of the scope of study of conservators, they are regularly called upon to assist in the best care of such remains (McGowan and LaRoche 1996). Considering the regularity with which conservators are asked to assist in the care of skeletal remains, it is prudent that dissemination of information on proper care practices for bones be provided through educational courses and publication of studies. “The treatment of human remains is an evolving topic, subject to updated and revised philosophies” (McGowan and LaRoche 1996:112), of which publication would help conservators keep abreast of the most current care practices. Though it is as true as with any other material, no one practice would prove best for all situations, knowledge of the variety of treatments and storage available would provide conservators with the greatest ability to continue the preservation of the remains.
In handling skeletal remains, their dual scientific and cultural value must be remembered at all times. Archaeologists and conservators must remember not to separate themselves from the remains they are handling; they must always remember that those remains were once, too, a whole person, an individual, with a personality and a life story. The cultural background of the individual should also be remembered, as it can provide a basis for the treatment and storage options that are most culturally acceptable; sometimes reburial may even be best practice. Care for individuals whose identity and therefore cultural background is unknown, though case dependent, should often include reburial in a condition relatively unaltered from first recovery (Ubelaker and Grant 1989).
Proper storage is likely to be the primary concern of conservators working with skeletal remains, as many conservation techniques used elsewhere may prevent further study of the remains. This study is often fraught with complications, as well, since they can damage the physical characteristics of the bone, though new, less invasive methods are being developed (Bolnick et al. 2012). Too often, bones are improperly stored at the excavation site, which then becomes long-term storage. Sound conservation practices should ensure that skeletal remains are properly stored in acid-free materials with environmental controls and correct cataloging of the remains. “The proper storage and treatment of human remains serve the interests of both an engaged descendant community and the scientific community” (McGowan and LaRoche 1996:116).
Working with human remains can be a sensitive subject, as it highlights many spiritual and philosophical belief systems. Concern for the proper scientific analyses and conservation practices of skeletal remains can communicate the respect shown for the individuals and help allay the concerns of descendant cultures.
