What is Reevaluation of Spiral Coprolites about?
The document discusses spiral coprolites, which are fossilized feces found coiled in a spiral shape. It was previously thought that these spiral fossils found in Permian rock formations in Kansas were fossilized intestines called enterospirae. However, the author reevaluates this and provides evidence that the spiral fossils are actually fossilized feces, or coprolites, based on comparisons to the spiral feces produced in the intestines of modern dogfish sharks.
