Mass extiction is significant decline of a certain group of fauceirs over a relatively short period of time. 
Mass extinction has to be distinguished from normal death rates in connection with faueir's normal turn-over. All evolving fauceirs face mass extinction at some level of evolution. Namely when those faucers grow so abundant that they begin to form a new master fauceir. Mass extinction is kind of a feedback process of a newly formed master fauceir to control its slaves. 
Mass extinction occurs whenever a master fauceir favors an increase in number of slave fauceirs instead of an increase in complexity. The mere quantitative growth leads to a shortage of resources. 
Examples
	- The extinction of Dinosaurs
 
	- Cretatious mass extinction
 
	- Reduction of population density by pests
 
	- Cyclic economic crises
 
	- Inflation
