Van, and this article was written by an AI machine too. That use of “archaic” is completely out of context for the tone of this article.
He took me awhile to figure out who discovered what in this poorly written article. The term “sleuthing” threw me off, as if they posted the photo online to see if anyone knew what it was.
All that said, pretty fitting that the parents of a dentist have a home with a human mandible in their flooring.
