* Tracks: Tracks, also known as trace fossils, are definitely considered fossils. They preserve evidence of the activity of an organism, like walking, feeding, or burrowing.

* Dung: Dung, or coprolites, can also be classified as fossils. They are fossilized feces, which provide valuable information about the diet and behavior of ancient animals.

So, while both tracks and dung are fossils, they are not traditional "body fossils" like bones or shells. They are instead trace fossils that offer a glimpse into the lives and actions of ancient organisms.
