Roughly 250 million years have passed since Earth experienced an extinction so profound, it's become colloquially known as the Great Dying.

Detection by mass spectrometry. A mass spectrum of an organic compound will usually contain a small peak of one mass unit greater than the apparent molecular ion peak (M) of the whole molecule. This is known as the M+1 peak and comes from the few molecules that contain a 13 C atom in place of a 12 C. A molecule containing one carbon atom will be …The Permo-Triassic Extinction. The end of the Permian period 252 million years ago saw the greatest mass extinction in the geological record.
