Fossils are amazing how they are formed. The process is fossilization. I was surprised to discover that a series of mistakes must happen in order for a fossil to be created. First some living creatures must die and must some how escape the scavengers that have a roll in the food chain. The once living has to then become entombed in mud and sand. The shroud must lie undisturbed for years so that mineralization can take place in which the tissue or cast gets filled in with sediment. Then this body turns to stone. The scientists that study these relics are called paleontologist.
Dates in paleontology are usually revised backward in time, since a new find may revise an event earlier the
Another method of dating is called molecular clock examine for genes which are descended from a common ancestral gene. Although very new this method sometimes clashes with conventional methods because its not well calibrated.
Volcanic ash can be used for dating. Ash known as mazama, with an age of 6,720 radiocarbon years, and Glacier Peak B ash located in glacier peak Washington with an age of 11,250 radio carbon years.
