‘Looks like collagen, behaves like collagen, and it’s 68 million years old! ’ (David Martill, University of Portsmouth, UK.) Of course, this again begs the question, and leaves unsolved how protein could have survived that long.C) could not possibly be present in such ‘old’ fossils generally prevents carbon dating being attempted.
The current method paleontologists use to date dinosaur fossils is a technique called relative chronology.The method estimates a fossils age relative to the known age of deposits of sediment in which it was found.Other critics, perhaps more familiar with the data, question certain aspects of the quality of the fossil record and of its dating.These skeptics do not provide scientific evidence for their views.Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it.
The majority of the time fossils are dated using relative dating techniques.The Wheeler Formation has been previously dated to approximately 507 million year old, so we know the trilobite is also about 507 million years old.But, how can we determine how old a rock formation is, if it hasn’t previously been dated? There are two main methods determining a fossils age, relative dating and absolute dating.Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages.The Evidence Hardens, 314(5801):920, 10 November 2006).
