As demonstrated above, the graptolitic succession of the Lower to Middle Ordovician is relatively incomplete in the Trail Creek Summit section. A more complete grap-tolitic succession (Fig. 3) can be pieced together from the faunal record of the region as documented by Carter and Churkin (1977), Dover et al. (1980), Ross and Berry

Faunal succession is the principle that different kinds of fossils characterize different intervals of time. This is because evolution and extinction are facts of nature. The principle of faunal succession was developed by an English surveyor named William "Strata" Smith (1769-1839).

The fossil content of rocks together with the law of superposition helps to determine the time sequence in which sedimentary rocks were laid down.Faunal succession was documented by Smith in England during the first decade of the 19th century, and concurrently in France by Cuvier (with the assistance of the mineralogist Alexandre Brongniart).

Smith’s principle of faunal sequence was another way of saying that there are discontinuities in the sequences of fossilized plants and animals. 2008-05-08 · Faunal Succession’s Legacy.

law of faunal succession The principle, first recognized at the beginning of the 19th century by William Smith, that different strata each contain particular assemblages of fossils by which the rocks may be identified and correlated over long distances; and that these fossil forms succeed one another in a definite and habitual order.

This concept is called the Law of Faunal Succession. Some fossils are particularly useful in telling time, these are called Index Fossils .

Figuring out when things happened during the long expanse of the Earth's history became a lot easier when William Smith (1769-1839) discovered the law of faunal succession. The concept grew of out his work on the science of stratigraphy (which he pretty much invented).

Faunal succession is the fundamental tool of stratigraphy and comprises the basis for the geologic time scale.
