Not only could Smith identify rock strata by the fossils they contained, he could also see a pattern emerging: certain fossils always appear in more ancient sediments, while others begin to be seen as the strata become more recent.
By following the fossils, Smith was able to put all the strata of England’s earth into relative temporal sequence.
About the same time, Georges Cuvier made the same discovery while studying the rocks around Paris.
Soon it was realized that this principal of faunal(animal)succession was valid not only in England or France but virtually everywhere.
It was actually a principle of floral succession as well, because plants showed the same transformation through time as did fauna. Limestone may be found in the Cambrian or—300 million years later—in the Jurassic strata, but a trilobite—the ubiquitous marine arthropod that had its birth in the Cambrian—will never be found in Jurassic strata, nor a dinosaur in the Cambrian.
Look at the four squares[

The findings of these geologists inspired others to examine the rock and fossil records in different parts of the world.
Where would the sentence best fit? [br]
