Global warming caused by volcanoes triggered mass extinction and wiped out 85% of the marine species

Global warming caused by volcanoes triggered a mass extinction that wiped out 85% of all marine species on Earth 450 million years ago, scientists say Scientists have proposed a new explanation for the late Ordovician extinction Researchers say they have heated stones that come from a stream in southern Scotland The rocks release large amounts of mercury, which indicates volcanic …

The world’s most mysterious mass extinction may have had an ozone depletion component

Throughout history, Earth has experienced at least five major mass extinctions that have wiped out most of the life around the world. Most of these events coincided fairly clearly with disasters such as asteroid strikes, geological activities and volcanic eruptions. However, an event is more of a mystery – the extinction of the late Devonian 360 million years ago. We …

Mass extinction 360 m years ago due to ozone layer erosion

A mass extinction 360 million years ago, in which many plants and freshwater animals on earth were killed, was caused by the depletion of the ozone layer. Scientists at the University of Southampton found evidence that high UV radiation was destroying the old forest ecosystem. This newly discovered extinguishing mechanism was caused by changes in Earth’s temperatures and climate cycle …

The study shows the erosion of the ozone layer, which is responsible for the mass extinction

Normal and malformed spores from East Greenland. Photo credit: John Marshall Researchers at the University of Southampton have shown that an extinction 360 million years ago in which a large part of the world’s plant and freshwater organisms was killed was caused by a brief depletion of the ozone layer, which protects the earth from harmful ultraviolet (UV) radiation . …

The latest discovery from the Florida Aquarium could help save the continental United States’ only coral reef from extinction

The Florida Aquarium celebrated Earth Day this year by announcing a historic feat that could help save the United States’ only living coral barrier reef from extinction. For the first time, scientists at the Aquarium Center for Conservation reproduced fluted cactus corals in human care. According to a press release, researchers made the “multi-night” breakthrough earlier this month. It is …

During the mass extinction events, volcanoes released approximately the same amount of CO2 as they do today

200 million years ago, a mass extinction wiped out about 76% of all species on earth – both terrestrial and marine. This event was called end-Triassic extinction or Jurassic-Triassic (J-T) extinction. At that time, the world was experiencing many of the same things Earth is now facing, including a warming climate and ocean acidification. A new paper shows that impulses …

The evolutionary adaptation helped cave bears hibernate, but could have led to extinction

The well-developed sinus system of the now extinct cave bear (top left) is associated with uneven mechanical stress distributions in bite simulations performed at UB (bottom left). The much less developed sinus system in living bears, for example the sun or the honey bear (top right), enables an even distribution of the mechanical stress over the forehead area, as can …

The newly discovered feathered dinosaur was one of the last birds of prey before extinction

This artist’s illustration of Dineobellator notohesperus shows her in an open landscape across what is now New Mexico, along with Ojoceratops and Alamosaurus in the background. Ikaria wariootia was a worm-like creature that lived 555 million years ago. It is the oldest ancestor in the family tree for most animals. This is the 3.67 million year old “Little Foot” skull. …
