Extinction Event facts

While investigating facts about Extinction Events and Extinction Events On Earth, I found out little known, but curios details like:

A creature known as a "Tardigrade" has survived all five mass extinction events.

how extinction events?

There were four mass extinction events before the one that killed the Dinosaurs. The most severe killed a staggering 97% of all species. All life on Earth today is descended from the 3% that survived.

What extinction event wiped out the dinosaurs?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what extinction event are we in. Here are 50 of the best facts about Extinction Events In History and Extinction Events Timeline I managed to collect.

what extinction event killed the dinosaurs?

  1. We are currently in Earth's sixth mass-extinction event, also known as the Holocene extinction

  2. The hoatzin is the last surviving species of a line of birds that diverged from all other birds 64 million years ago, just after the dinosaur extinction event, and that hoatzin chicks have claws on their wings

  3. Humans are killing off so many species, it's called the Holocene Extinction Event

  4. The Earths first mass extinction event was caused by the newly formed Oxygen molecule. Known as the Oxygen Holocaust, the event caused the mass extinction of cellular life all over the planet some 2.4 Billion years ago.

  5. The dinosaur extinction event is marked by a thin layer of sediment all over the world, which contains 160 times as much Iridium as normal - evidence of the global devastation caused by an asteroid impact

  6. The Horseshoe Crab Has Survived 4 Mass Extinction Events

  7. There were 5 mass extinction events on earth, with the extinction of dinosaurs not even being the largest.

  8. Humans have a relatively low level of genetic variation because we are all descendants of ~10,000 humans that survived a massive extinction event ~70,000 years ago. One tribe y'all.

What is true about extinction event?

You can easily fact check it by examining the linked well-known sources.

Archaebacteria are considered to be one of the earth's oldest forms of life. They survived the extinction events that killed off the dinosaurs.

The Tardigrade has survived all five mass extinction events, can survive in outer space, without food or water AND can be revived after 30 years of being frozen. - source

Trilobites were made extinct approximately 250 million years ago when 90 percent of all of the species on earth were wiped out. This event is referred to as the "Great Dying", or "Permian Extinction". It is not known whether it was an exploding supernova or volcanic eruption that caused the event.

During the Paleocene epoch the world was recovering from the extinction event and mammals were fairly small. It is believed that they were all smaller than 10 kilograms.

When is the next extinction event?

In the Pleistocene epoch ice ages were frequent, and a major extinction event wiped out several species including Neanderthals. Homo sapiens evolved during this epoch.

How many extinction events?

That, besides the extinction event that wiped out the dinosaurs, there has been 4 other Mass Extinction events to occur millions of years apart that would nearly wipe out all life on earth.

There is a star system called WR 104 that is expected to go supernova in a few thousand years. If its gamma ray burst hits the earth the result may be a mass extinction event.

An impact event occurs when an asteroid collides with a planet. They can be devastating enough to cause extinction events.

The super volcano at Lake Toba, which erupted 74,000 years ago and almost drove humanity to extinction; with 10,000 humans surviving the event, and only 2,000 of whom were able to reproduce

There is a bigger volcanic process than super volcanoes called Large Igneous Provinces that appear to have occurred simultaneously with extinction events.

When is the next extinction rebellion event?

They began to decline about 500 million years ago but did not die out until the big extinction event 240 million years ago.

The Earth has underwent 5 mass extinction events, one of which wiped out 90% to 96% of all species. Another may have been caused by a gamma ray burst.

Gamma Ray Bursts could possibly be the cause behind the Ordovician–Silurian extinction event, an event that left all life on Earth restricted to the oceans.

In 1995, Edward Teller (father of the H-bomb) proposed that U.S. and Russian weapons designers collaborate on designing a 1000 megaton nuclear explosive device for diverting extinction class asteroids, which would be employed in the event that one were on an impact trajectory with earth.

We are living in the 6th Extinction Event and that humans are credited with causing it.

How many extinction events have there been?

A University of Oxford conference estimated the likelihood of a human extinction event occurring by 2100 to be 19%

The first major extinction event on eart was caused by the creation of oxygen.AKA The great oxygenation event.

Major study confirms that Earth is currently witnessing the start of a mass extinction event the likes of which have not been seen for at least 65 million years. It is being precipitated by human actions over past 500 years

Although trilobites were the most famous creature at the time of the great extinction event to be wiped out entirely, a variety of insects, armored fish, sharks, various organisms, and many mammals were also killed off.

Every time in the past, for example 55, 183, 200, and 250million years ago, when levels of CO2 have risen as rapidly as they are today, there have been major extinction events, with up to 96% of all species lost.

Wilkes Land crater underneath the ice in Antarctica is the most probable cause of the Permian Extinction Event

About the Permian Triassic extinction event (~251 million years ago) that killed almost 96% of all life on earth.

The earliest form of grasses didn't exist until 60 and 55 million years ago, after the major extinction events that ended the age of dinosaurs and the Cretaceous period.

Plants and bivalves in Antarctica were little affected by the K/Pg extinction event, as they were already adapted to the cold and dark of the polar winter. This raises the possibility that other cold adapted fauna survived for longer in Antarctica, including dinosaurs.

Over the past 450 million years, life on Earth has been devastated by five mass extinction events, but some geologists think there was a sixth mass extinction.

Human activity is currently causing the Earth's sixth major extinction event; over just the last century, species have gone extinct at a 1000x faster rate than normal, all because of humans

In 1995, Edward Teller (father of the H-bomb) proposed that U.S. and Russian weapons designers collaborate on designing a 1000 megaton nuclear explosive device for diverting extinction class asteroids, which would be employed in the event that one were on an impact trajectory with earth.

Some theories suggest that the Ordovican-Silurian extinction events that occurred on earth between 447 and 443 million years ago were the result of a supernova. This is considered to be the fifth mass extinction on earth.

Cyanobacteria are responsible for the extinction of most anaerobic bacteria at the time and were a cause of the of the Great Oxidation Event

There was a mass extinction 66 million years ago which wiped out 3/4th of the existing species known as Cretaceous–Paleogene extinction event.
