Trampling can produce linear marks that superficially resemble cut marks, but they tend to be randomly oriented rather than associated in parallel groups, and their cross-sectional profile often shows mechanical damage patterns different from those of intentional cuts.

Root etching occurs when plant roots grow across bone surfaces and produce chemical dissolution along their path.

Root marks are typically branching and sinuous in pattern, following the dendritic structure of root systems, and their texture is chemically etched rather than mechanically cut.

Distinguishing among these different types of modifications requires careful examination under magnification — typically using a scanning electron microscope or a high-powered optical microscope — and the application of specific criteria that have been developed through experimental work in which archaeologists have produced controlled modifications under known conditions and examined the results.

The development of these taphonomic methods over the past several decades has been one of the most important methodological advances in prehistoric archaeology, enabling much more reliable attribution of bone modifications to specific causes.
