Stratification: how fast can it go?
That is the big question. Slow forming of strata (on average) is essential for the monophylic model because time seems to be essential for the large changes from simple one celled life forms to the great diversity of complex multicellular life forms we see now. Usually an average speed of 20 cms per 5000 years is supposed. Fast forming of strata supports the idea of polyphyly. Catastrophies will cause a fast forming of strata as the aftermath of the eruption of Mount St Helens in 1980 shows (picture to the right: 4 meters formed in a matter of hours). The experiments of Berthault (embedded video) show that horizontal strata are not necesseraly formed by superposition: lateral forming and horizontal setting can go together. This can have great implications, especially for the relative dating of fossils: F4 being younger than F1 in the drawing below.
Forming of fossils
Fossils can be formed in a number of ways:
Geological column, index fossils and dating
All strata put into one thick pack of layers produces a geological column which appears in many textbooks - but it is a construction and cannot be found as such. Index fossils (only found in certain strata) are used to identify and date many strata because radiometric dating can only be used for a few types of rock.
Radiometric dating is questioned by some because of its assumptions: the clock at zero when the strata where formed, running with a known speed and no leaks involved. The speed of radio-active decay also depends on other factors like the speed of light. If the speed of light was higher in the past, the same is true of the speed of radio-active decay.
Proposing a flood model
Many observations support the idea of a global flood being reponsible for most strata (see workbook p 38/39). It is not easy to know how this happened - the scale is so much larger than what we are familiar with. Maybe something like the following happened:
Dragons and dinosaurs
Very interesting are the stories on dragons - up to pretty recent times - and the soft tissue that has been found in dinosaur fossils. Link nr 12-14 supply more information about that and the video "Dragons or Dinosaurs" discusses the evidence.
