superposition and carbon dating
There are a few ways that single-celled organisms can move. These are by crawling on pseudopodia, using cilia, or using flagella.
In what ways are fossils useful to geologist?
Radioactive isotope dating (potassium, argon) and relative dating, comparing with fossils of the same characteristics with known dates. Particularly if they are known to be 'zone fossils'

Stratigraphy, the relative positon of fossils in a sediment bed, is a common method. Assuming the beds lie in their natural position.Dating by using radioactive decay is another method used mainly for sub-fossil material such as archaeological artifacts; or for materials of geological age.
Two ways to date fossils are relative dating, which involves determining the age of a fossil in relation to other fossils or geological layers, and absolute dating, which provides a numerical age for a fossil using techniques like radiometric dating.

People can identify fossils by their shape, size, and texture. Fossils might closely resemble the bones or shells of modern organisms, but also exhibit distinctive features that indicate they are ancient. Additionally, the location where a fossil is found can provide clues about the type of organism it belonged to.

Microorganisms multiply in a few different ways. They can multiply using binary fission, mitosis and meiosis. Different organisms use different ways.
they show us what our ancestors did or if we've evolved and we looked different then, they show us what we had back then, sometimes what happened back then, we can see how old certain items are to see when it was used etc.
