What does the principle of faunal succession state?

Different species of flora and fauna are found in a specific order in the sedimentary rock strata in regard to the geological time they lived in.

Explanation:

The principle or law of faunal succession, proposed by English geologist William Smith, states that different species of both flora and fauna are found in a specific order in the sedimentary rock strata in regard to the geological time they lived in. These fossils follow a succession, that is, they succeed each other vertically.

For example, two organisms that lived during different geological periods, let's say one from the Triassic and the other from the Ordovician, will never be found in the same stratum because they are separated by thousands to millions of years.

This pattern is crucial for paleontologists because it allows them to determine which species inhabited a certain ecosystem during the same geological era or period.

imparadis't in one anothers arms  

the happier eden, shall enjoy their fill  

of bliss on bliss, while i to hell am thrust,  

where neither joy nor love, but fierce desire,  

among our other torments not the least,  

still unfulfill'd with pain of longing pines;  

yet let me not forget what i have gain'd  

from their own mouths; all is not theirs it seems:  

one fatal tree there stands of knowledge call'd,  

forbidden them to taste: knowledge forbidd'n?  

suspicious, reasonless. why should their lord  

envie them that? can it be sin to know,
