I went to the Carnegie Museums in Pittsburgh a couple of weeks ago, and they had warnings for if an exhibit had human remains in them (even if they were not visible, I.e. in a mummy).
They also had a short blurb on the ethics of displaying human remains, especially if the remains on exhibit didn't/couldn't give consent. I found it very thought provoking honestly.
To extend it, I found it interesting that there was a lot of discussion on the ethics of showing human remains (taxidermy, in alcohol solution, bones, etc.), but then they showed a lot of animal remains and there was no discussion on that, especially when I would assume that many of the animals shown in the museum were killed for the specific reason of having them on a museum or for study.
