The 5 Major Mass Extinctions

Big 5 Mass Extinctions Poster By Budcharles On Deviantart The five mass extinctions. there have been five mass extinction events in earth’s history, at least since 500 million years ago. we know very little about extinction events in the precambrian and early cambrian earlier, which predate this.4 these are called the "big five" for obvious reasons. in the chart, we see the timing of events in earth. The third major mass extinction was during the last period of the paleozoic era, called the permian period. this is the largest of all known mass extinctions with a massive 96% of all species on earth completely lost. it is no wonder, therefore, that this major mass extinction has been dubbed “the great dying.”.

Mass Extinctions National Geographic Society The 5 mass extinctions . ordovician silurian extinction: ~ 440 million years ago. species made extinct: 85%. by the end of the ordovician period the seafloor was teeming with shelled creatures. 2. end devonian: the long road to oblivion. the placoderm lineage of ferocious looking armored fish, such as dinichthys herzeri, ended during the end devonian mass extinction, a long downward spiral in biodiversity. (credit: science history images alamy stock photo) when: 359 million to 380 million years ago. Cretaceous paleogene extinction. perhaps the most famous of the major mass extinctions is the cretaceous paleogene, or k–pg, extinction, which occurred some 66 million years ago. it marked the end of about 67 percent of all species living immediately beforehand, including the non avian dinosaurs. as a result, mammals and birds (avian. 5. ordovician–silurian extinction (o s) the ordovician–silurian extinction actually consists of two consecutive mass extinctions. when combined together, o s is widely considered to be the second most catastrophic extinction event in history. about 450–440 million years ago, 60% to 70% of all species were vanquished.

Since the cambrian explosion, five further major mass extinctions have significantly exceeded the background extinction rate. the most recent and best known, the cretaceous–paleogene extinction event , which occurred approximately 66 ma (million years ago), was a large scale mass extinction of animal and plant species in a geologically short. Mass extinction events. there’s a scientific consensus that the planet has undergone five major mass extinction events within the last 450 million years, with each destroying 70 95% of the species of plants, animals and microorganisms that existed previously.
