Clocks in the rocks radioactive dating method
They are very important index fossils for ‘dating’ and correlation of rock layers, for example, across Europe, particularly for the so-called Cretaceous and Jurassic periods of the geological time-scale, C ‘dated’ at 23,000–23,500 years BP.However, based on evolutionary and uniformitarian assumptions, the ammonite and belemnite index fossils in this rock ‘date’ it at about 189 million years. Furthermore, it is somewhat enigmatic that broken pieces of wood from land plants were buried and fossilised in a limestone alongside marine ammonite and belemnite fossils.Uniformitarians consider limestone to have been slowly deposited over countless thousands of years on a shallow ocean floor where wood from trees is not usually found.However, the radiocarbon ‘dating’ of the fossil wood has emphatically demonstrated the complete failure of the evolutionary and uniformitarian assumptions underpinning geological ‘dating’.To qualify as an index fossil, a particular fossil species must be found buried in rock layers over a very wide geographical area, preferably on several continents.On the other hand, the same fossil species must have a narrow vertical distribution, that is, only be buried in a few rock layers.A far superior explanation for this limestone and the mixture of terrestrial wood and marine shellfish fossils it contains is extremely rapid burial in a turbulent watery catastrophe that affected both the land and ocean floor, such as the recent global biblical Flood.The 23,000–23,500 year BP C ‘date’ for this fossil wood is not inconsistent with it being buried about 4,500 years ago during the Flood, the original plants having grown before the Flood.
The pen is not only for scale, but points to an end-on circular profile of a belemnite fossil sitting directly underneath the fossil wood (sampled as UK-HB-1). Both laboratories used the more sensitive accelerator mass spectrometry (AMS) technique for radiocarbon analyses, recognised as producing reliable results even on samples with minute quantities of carbon.2, of Index fossils and geologic dating, aside below). To evolutionary geologists, fossils are still crucial for dating strata, but not all fossils are equally useful.Those fossils that seem to work well for identifying and ‘dating’ rock strata are called ‘index’ fossils.Of course, uniformitarian geologists would not even test this fossil wood for radiocarbon.They don’t expect any to be in it, since they would regard it as about 189 million years old due to the ‘age’ of the index fossils.
