Fossil record dating assumptions

For instance, if we find a fossil bone below the strata 3 rock level shown above, we assume that the animal most likely lived at a time before that layer was formed.However, we must be careful to note whether or not the fossil comes from the mixed strata zone of the filled in hole..The method assumes that variations in the number of different fossils at any given time are a reflection of how much rock was available.It has been used in more than 150 published research papers since it was first used in 2007.

Young-earth creation geologists have long held that most sedimentary strata resulted from waterborne deposits during Noah’s Flood.These processes result in All of these processes confuse the stratigraphic record.In many cases, however, it is possible to reconstruct the original sequence of strata so that they can be used for relative dating.Early geologists, in the 1700s and 1800s, noticed how fossils seemed to occur in sequences: certain assemblages of fossils were always found below other assemblages. Since 1859, paleontologists, or fossil experts, have searched the world for fossils.In the past 150 years they have not found any fossils that Darwin would not have expected.
