The principle of fossil succession states that fossils found in younger layers of rock tend to be more similar to current species, while fossils in older layers differ more. This is because newer fossils represent species that have evolved and survived to the present day, while older fossils may belong to species that have become extinct. This pattern helps scientists understand the evolution and biodiversity of life on Earth.

It Gave evidence and the fossil organisms on the bottom or older layers were more primitive than those in upper or newer layers.
Fossils found in deeper rock layers are generally older than those found in shallower layers, reflecting the idea that organisms in deeper layers lived earlier in Earth's history. By examining the sequence of fossils in different layers, scientists can see how species have evolved over time, with simpler organisms in older layers and more complex ones in younger layers. This helps to reconstruct the history of life on Earth and understand how species have changed and diversified over millions of years.
Superposition is the principle that states that, in undisturbed strata, newer layers will be deposited over older layers; thus, in a core sample, those samples of earth and rock nearest the surface will be newer in age than those beneath them.
The Principle of Superposition argues that rock layers towards the top are younger than those at the bottom. This was the principal technique used in the early days.Fossils have discontinuities - a group will appear, and after a time will vanish again. But very similar fossils appear around the world at the same time.This subject paleontology, has good records, and a newly found fossil can usually be identified by comparison with the paleontological record.Today of course, radiometric dating is used very widely to determine the age of both rocks themselves, and of fossils. These techniques use the half-life of radioactive elements to determine the age.

Sediments are usually found in layers because they are deposited gradually over time, with newer sediments settling on top of older ones. Different sediment types can produce distinct layers based on factors such as grain size, mineral composition, or changing environmental conditions. This layering process helps to provide a historical record of the Earth's geologic and environmental changes.
Principle stating that older rock layers are beneath younger rock layers.
Not as old as those found deeper
Due to faulting or folding.
The fossils that are further up among the layers would be newer because they were formed before the others.When fossils are further down in the ground they are older because they had been covered up longer in time.
