Disinterred is one thing. There could be any number of reasons why persons remains would need to e disinterred. I don’t even have to much trouble with studying the persons remains. But displaying them has always seemed like un-needed disrespect. Most of us know what skeletal remains look like, note that human remains were found keep it private and return the remains to the most appropriate local authority. This kind of activity has made Native Americans rightfully hostile to allowing examination of remains in all cases. Which makes it harder for us (all of us) to understand that pre-history.
What happened here is very much like the display people in the Victorian era. Villages of “primitive” people displayed for entertainment and to make the viewer feel superior.
