The researchers discovered evidence of G. duodenalis under stone toilet seats previously found at two large sites that were likely elite residences dating to the seventh to sixth centuries B.C. The stone blocks had a curved surface for sitting, a large central hole for defecating, and a smaller hole that was possibly for urination, and were situated above a cesspit. Because the ancient toilets were still in their original locations, a unique opportunity arose for specialists to identify microorganisms in the old poop.I was not familiar with the "house of Ahiel" toilet, but you can read more about it here. I noted the discovery of intestinal parasites in the fecal matter from the toilet excavated at Armon Hanatziv here. Follow the links from there, plus here for more ancient Latrine News.
