Which of the following terms describes animal bones with archaeological significance?

The term that best describes animal bones with archaeological significance is ecofacts. Ecofacts are organic remains that provide information about past human-environment interactions, such as animal bones, plant remains, and pollen. They are important in understanding the diet, subsistence practices, and environments of past human populations.

In archaeological contexts, ecofacts complement artifacts, which are human-made objects, by indicating the natural resources available to and used by people. Features refer to non-portable structures or activities, like hearths or postholes, and stratigraphy is a method of studying layers of soil and the ordering of archaeological deposits, rather than specific objects or remains. Thus, identifying animal bones as ecofacts highlights their role in reconstructing past ecological and cultural dynamics.
