A new study on prehistoric big cats suggests that finicky eaters usually do not survive mass extinction events.
According to researchers, around 252 million years ago, microbes which are believed to produce methane caused a major disaster may have led to the mass extinction in earth`s history.
Researchers have said that crocodile-like amphibians and later the precursors of the known plesiosaurs and ichthyosaurs went in search of prey in the oceans soon after the end of the mass extinction.
Something wiped out nearly all life on Earth more than 250 million years ago, and whatever unleashed this mass die-off acted much faster than previously thought, scientists said Monday.

Marine animal groups like ammonoids and conodonts already peaked three or four million years earlier, namely still during the Ear-ly Triassic, researchers say.
A new discovery has challenged the widely held assumption that a period of explosive evolution quickly follows for survivors of mass extinctions.
Terrestrial biodiversity recovered much faster after mass extinction, which occurred between the Permian and Triassic periods, than previously thought.
Researchers had always assumed it took the Earth as long as five million years to recover from the species collapse.
A massive emission of methane led to an increase in atmospheric temperature around the globe 200 million years ago.
Mankind may have unleashed the sixth known mass extinction in Earth`s history, according to a paper.
A scientific analysis of millions of years of data has suggested that if the course of human history is any model, then the wheels are already turning on Earth’s sixth mass extinction.
