Animal food evidence in the coprolites includes small rodent bones, fish scales and bones, and the occasional larger mammal hair or bone fragment.

This evidence is consistent with a broad-spectrum diet — the exploitation of a wide range of animal food sources rather than specialization in a single prey type — that is characteristic of effective hunter-gatherer subsistence in environments where any single prey type can be unreliable.

The combination of plant and animal evidence in the Paisley coprolites documents a human population that was not dependent on megafauna hunting alone.

The Pleistocene megafauna — mammoths, horses, and the other large animals of the late Pleistocene — appear to have been part of the subsistence landscape of the earliest Americans, and some early sites document unambiguous evidence of megafauna hunting or processing.
