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'

Organisms can be preserved as fossils through several methods, including permineralization (minerals infiltrating bone or wood), natural casts (sediment filling in the shape of an organism), amber preservation (organisms trapped in tree resin), freezing (organisms preserved in ice), and desiccation (organisms dried out in arid conditions). Fossils can reveal crucial information about Earth's history, such as the types of organisms that existed at different times, evolutionary transitions, and past environmental conditions. They also provide insights into extinction events and the changes in biodiversity over geological time. By studying fossils, scientists can reconstruct ancient ecosystems and understand the Earth's climatic shifts.
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.
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.
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.
