Fossil record dating assumptions
The practice of using fossil beds to date these rock strata started in the 19th century as a way to more accurately date the layers worldwide.
(https://en.m.wikipedia.org/wiki/Geologic_time_scale). Evolutionists need to believe that life evolved slowly over millions of years, and that the record of all earth’s creatures is now preserved in the layers of rocks. If true, the oldest life forms would appear on the bottom of the column with successively younger things piled in the layers on top.
(Welles, Samuel Paul, “Paleontology,” In some cases darwinists have recognized circularity as a typical problem in evolutionary models and worked to avoid it.
“To test this idea, we matched earliest Cambrian records of carbon isotope variability from Siberia, Mongolia, and China with a Moroccan record constrained by five radiometric ages from interbedded volcanic ashes.
(Some of the following quotes are as cited in Morris, 1997 and Snelling, 1990).
The series of quotes begins with a vivid illustration of this circular reasoning in action.

Paleontology is the study of life in past geologic periods (fossil plants and animals), incorporating knowledge of an organism's phylogeny, relationships to existing organisms, and correlation to an established chronology of Earth History.
This time interval was from 542-520 million years ago.
This approach avoids the circularity associated with using fossils to correlate rocks, and then using those correlations to infer biological patterns…” (“Cambrian Explosion: New Timeline for Appearances of Skeletal Animals in Fossil Record,” , Nov.
In my last two articles I talked about carbon dating (for formerly living things) and general radiometric dating (for minerals) and the problems with both methods.
Now we’re going to mix the two and ask how scientists come up with dates for fossils that are supposedly much older than the maximum “age” carbon dating can measure (57,300 years).
