Definition Areas where sediment surface patterns are dominated by tracks and trails left by locomotion of mobile epifauna (e.g., snails, holothurians, crustaceans), and other fauna that are no longer present. These are common in deeper waters, and in other areas where sediments are less disturbed by physical energy. The appropriate invertebrate size modifier (e.g., Megafaunal, Macrofaunal) may be used to describe the sizes of the organisms suspected of leaving the marks being evaluated.
