It has a skull but no spinevelvet smooth skin, and a terrifying pit of a mouth that's lined with rows of razor-sharp teeth. Now researchers could accurately calculate the age of any object made of organic materials by observing how much of a certain form of carbon remained, and then calculating backwards to determine when the plant or animal that the material came from had died. By measuring the rate of production and of decay both eminently quantifiablescientists were able to estimate that carbon in the atmosphere would go from zero to equilibrium in 30, — 50, years.
