Video: Difference Between Ediacaran Extinction And Cambrian Explosion
The key difference between Ediacaran extinction and Cambrian explosion is that Ediacaran extinction is the first know mass extinction of macroscopic eukaryotic life while Cambrian explosion is the sudden appearance in the fossil record of complex animals with mineralized skeletal remains.
Ediacaran extinction and Cambrian explosion are two events that are most important in the history of life on Earth. Ediacaran extinction immediately precedes the Cambrian explosion. Ediacaran extinction refers to the mass extinction of macroscopic animals. It is followed by Cambrian explosion or the rapid appearance of mineralized skeletons and complex trace fossils of complex animals. Ediacaran extinction occurred 542 million years ago while Cambrian explosion occurred 541 million years ago.
