Extinction event The most recent and debatably best-known, the Cretaceous–Paleogene extinction event, which occurred approximately 66 million years ago (Ma), was a large-scale mass extinction of animal and plant species in a geologically short period of time.

Phanerozoic Paleogene [edit]. The Paleogene spans from the extinction of the dinosaurs, some 66 million years ago, to the dawn of the Neogene twenty three million years ago. It features three epochs: the Paleocene, Eocene and Oligocene.

- A major extinction, the Kellwasser event, occurred at the boundary that marks the beginning of the last phase of the Devonian period, the Famennian faunal stage (the Frasnian–Famennian boundary), about 375–360 million years ago.[1][2] Overall, 19% of all families and 50% of all genera became extinct.[3] A second, distinct mass extinction, the ...

- One of the five greatest mass extinction events in Earth's history occurred at the end of the Triassic, c. 200 million years ago. This event ultimately eliminated conodonts and nearly annihilated corals, sphinctozoan sponges and ammonoids. Other strongly affected marine taxa include brachiopods, bivalves, gastropods and foraminifers.

Timeline of the evolutionary history of life The five largest extinction events in earth's history since are these: 1  End of the Ordovician: 440 million years ago, 86% of all species lost, including graptolites. 2  Late Devonian: 375 million years ago, 75% of species lost, including trilobites.

The Mesozoic Era: Facts, Events & Timeline THE MESOZOIC ERA. The Mesozoic era is commonly subdivided into three geologic periods: Triassic (252 to 201.3 million years ago). Jurassic (201.3 to 145 million years ago). Cretaceous (145 to 66 million years ago). The Mesozoic era begins in the wake of the largest extinction in Earth's history. This extinction took place 252 million years ago and resulted in 96% of marine life and 70% of terrestrial life dying out.

- There have been five mass extinction events throughout Earth's history: The first great mass extinction event took place at the end of the Ordovician, when according to the fossil record, 60% of all genera of both terrestrial and marine life worldwide were exterminated.

- Scientists generally agree that the reason for any mass extinction can be traced to a variety of environmental factors that may have resulted from a triggering event. The extinction that occurred at the end of the Permian period, 250 million years ago, was probably the most severe in Earth's history.

Permian Main article: Permian–Triassic extinction event. The Permian ended with the most extensive extinction event recorded in paleontology: the Permian-Triassic extinction event. 90% to 95% of marine species became extinct, as well as 70% of all land organisms. It is also the only known mass extinction of insects.

Timeline of the evolutionary history of life The first known mass extinction in earth's history was the Great Oxygenation Event 2.4 billion years ago. The event led to the loss of most of the planet's obligate anaerobes. The five largest extinction events in earth's history since are these: 1  End of the Ordovician: 440 million years ago, 86% of all species lost, including graptolites.  Late Devonian: 375 million years ago, 75% of species lost, including trilobites.

Microbes May Have Caused Earth's Biggest Extinction View full size image. A microbial feeding frenzy may have fueled the biggest mass extinction in Earth's history, new research suggests. The findings suggest that bacteria, with a little help from massive volcanism, produced large quantities of methane, thereby killing 90 percent of life on the planet. Mass extinction.

Cretaceous Period: Animals, Plants & Extinction Event The Cretaceous Period was the last and longest segment of the Mesozoic Era. It lasted approximately 79 million years, from the minor extinction event that closed the Jurassic Period about 145.5 million years ago to the Cretaceous-Paleogene (K-Pg) extinction event dated at 65.5 million years ago.

Lack of oxygen led to first mass extinction This was what happened during the first mass extinction of animal life on the Earth, 440 million years ago. (Photo: Colourbox). With its warm climate and plenty of food, the Earth was a good place to live for the many animals with shells, legs and teeth. Animal life had just conquered the oceans 440 million years ago.

Finally confirmed: An asteroid wiped out the dinosaurs The Cretaceous–Paleogene extinction was the last great extinction event to occur on Earth, and is most notable for causing the diversification of mammals that eventually resulted in Homo sapiens. 66 million years ago an asteroid roughly 15 kilometers (9 miles) wide hurtled into Chicxulub, Mexico.

Mass Extinctions As new species evolve to fit ever changing ecological niches, older species fade away. But the rate of extinction is far from constant. At least a handful of times in the last 500 million years, 50 to more than 90 percent of all species on Earth have disappeared in a geological blink of the eye.Though these mass extinctions are deadly events, they open up the planet for new life-forms to emerge.Dinosaurs appeared after one of the biggest mass extinction events on Earth, the Permian-Triassic extinction about 250 million years ago.s new species evolve to fit ever changing ecological niches, older species fade away.

The circles correspond to the five major mass extinctions: (1) Late Ordovician; (2) Late Devonian; (3) Late Permian; (4) Late Triassic; and (5) end-Cretaceous.

Paleozoic The Paleozoic Era ended with the largest mass extinction in Earth's history, the Permian–Triassic extinction event. The effects of this catastrophe were so devastating that it took life on land 30 million years into the Mesozoic Era to recover. Recovery of life in the sea may have been much faster.
