Detecting a fairly recent 'doomsday', destroying 63% of animals

Examining hundreds of fossils, scientists have discovered a terrifying apocalypse that once sowed death across Africa and Arabia during the Early and Early Early Ages.

According to Science Alert, it is the most recent mass extinction to occur on Earth and has not been recorded before. It occurs during the transition of the global climate from swamp to icy.

By collecting data from hundreds of fossils from five groups of mammals, a team of scientists led by Dr Dorien de Vries from the University of Salford (UK) has recorded the disappearance of 63% of animals worldwide. Africa and Arabia during that great extinction.

But unlike other mass extinctions that have occurred on the planet, many species have shown strong vitality by reappearing in the fossil record a long time later, rather than disappearing completely like species. dinosaur. That is, somehow, a small number of individuals still exist, greatly evolved to adapt and reproduce again.

"After a few million years, these groups began to reappear in the fossil record, but with a new look," Dr. Vries told Sci-News . Meanwhile, Dr. Steven Heritage from Stony Brook University and the Duke Lemur Center's Museum of Natural History (USA), co-author, said: "Clearly there was a major extinction event, then followed. It's a period of recovery."

This "doomsday" occurred about 30 million years ago, ie the beginning of the Oligocene (Tien Tan, Paleogene, or Ancient Near), but it seems to have been fragmented since the end of the Eocene (Thuy Tan) . It can be said that the "knot" Thuy Tan - Tien Tan brought catastrophic genocide, but made an evolutionary leap for Earth's creatures.

The study has just been published in the scientific journal Communication Biology.
