The organisms in the Cretaceous period and Permian Period are now extinct.
The emergence and demise of specific living forms are represented by time periods on the geologic time scale that span hundreds of millions of years. A mass extinction is a period of geologic time when a large number of plant and animal species go extinct, sometimes within a few thousand to a few million years.
Life has recovered after each of the five significant mass extinctions that have taken place during the past 500 million years. Because it led to the extinction of the dinosaurs, the mass extinction at the end of the Cretaceous Period is the most well-known. However, the Permian Period's end saw the most extreme one in terms of the number of species destroyed.
