3.2 In the earliest 1800s, William Smith in England and Georges Cuvier in France used the successions of faunas in stratified rocks for mapping. This led to the development of the principle called the law of faunal succession: distinct faunas succeed one another regularly in the rocks. Why fossil faunas work this

principle of faunal succession is a stratigraphic principle where geologists use fossils in the rock to help interpret the relative ages of the rock.
Faunal Succession The layers of sedimentary rocks in any given location contain fossils in a definite sequence; the same sequence can be found in rocks elsewhere, and hence strata can be correlated between locations (William Smith). Foraminifera Single-celled marine organisms with shells.
In this paper we quantitatively evaluate planktonic foraminiferal species abundance patterns in order to measure relative rates of change in an evolving community as a whole.
Faunal succession is the principle that fossil assemblages succeed one another in a recognizable order, allowing geologists and paleontologists to correlate the ages of rock layers.
26 Οκτ 2017 · In this article we shall introduce the principle of faunal succession, and discuss how we know it is valid and why it should be so. In subsequent articles we shall discuss further how it can be applied to stratigraphy.
