Faunal Succession
Faunal succession
The principle you are referring to is known as the Law of Superposition in geology, which states that in undisturbed layers of rock, the oldest rocks are at the bottom and the youngest are at the top. This principle helps geologists to determine the relative ages of rocks and fossils.
The principle of Fossil succession states that fossil organisms succeed one another in a definite and determinable order. Therefore, any time period can be recognized by its fossil content.
The Law of Fossil Succession states that fossil organisms originate, coexist, and disappear from the geologic record in a definite sequential order.
This concept is known as the principle of faunal succession, which states that fossil organisms succeed one another in a definite and recognizable order. By studying the fossil assemblages found in rock layers (strata), geologists can determine the relative ages of those layers based on the organisms they contain. This principle is fundamental in stratigraphy and biostratigraphy for interpreting Earth's history.
No, "supersede" and "succeed" have different meanings. "Supersede" means to take the place of or replace something, while "succeed" means to achieve a desired outcome or to follow in sequence.
succeed one another in a definite order
A sequence of steps that must be taken, or activities that must be performed well, for a strategy to succeed.

will succeed
