Question

In 2020, Borry et al. developed an “ID” method for determining this substance’s source. Population trends in ancient settlements can be determined by comparing the amount of a certain 27-carbon stanol with its “epi” derivative in this substance. They’re not bog bodies, but “paleo” examples of this substance form protective outer shells thanks to the Maillard reaction. An extremely large example of this substance belonging to a Viking is named for Lloyd’s Bank. The presence of this substance in the Paisley Caves is some of the earliest evidence of (*) human habitation in North America. Mary Anning discovered the first coprolites, which (10[1])are fossilized (10[1])examples of (10[1])this non-hair substance that can be analyzed (10[1])to determine parasitic infections or diet. For 10 points, name this substance that, when used as fertilizer, is called manure. ■END■

ANSWER: feces [or dung or turd or scat or poop or excrement or shit; accept manure; accept other synonyms; accept paleofeces; accept coprolites until read; accept coproID] (CoproID is particularly useful in separating human feces from dog feces; coprostanol is used as a fecal biomarker in archaeology.)
