By the 1830's Adam Sedgwick and Roderick Murchison established a correlation between the various types of fossils and the rock formations in the British Isles.
It was found that certain fossils, now referred to as index fossils, were restricted to a narrow zone of strata.
(The principle of superposition was recognized as early as 1669 by Steno.) Reverend Benjamin Richardson and Reverend Joseph Townsend were a couple of early geologists involved in this work. Obviously, even Lyell was not pushing evolution at the time.One would think that the flood sediments (gathered from the four corners of the old antediluvian world) and their associated igneous rock (formed during the flood) would all register very little radiometric age.At the very least we would expect random fluctuations if the radiometric methods were totally at sea.By 1830 Lyell's famous textbook, Principles of Geology, came out. Such was the age of the great creationist geologists!The principle of faunal succession in the geologic record was established by direct observation as early as 1799 by William Smith.
