Antarctic Fossils Suggest That Mass Extinction Event in Polar Regions as Rapid and Severe as Elsewhere in the World
A new study of more than 6,000 marine fossils from Antarctica reveals that the mass extinction event, which killed dinosaurs, was sudden and just as deadly to life in the polar regions.

A new study, published in the journal Nature Communications revealed that animals living in the Polar Regions suffered from the sudden and deadly effect of the mass extinction event just like elsewhere in the world.

Previously, scientists believe that animals in the Polar Regions are far enough away from the cause of the extinction to be badly affected. They also proposed that organisms living in the poles would have been more resilient to global climatic changes associated with an asteroid impact due to their high adaptability in the environment that were always strongly seasonal.

However, a new study involving a six-year process of identifying more than 6,000 marine fossils ranging in age from 69- to 65-million-years-old suggests otherwise.

“Our research essentially shows that one day everything was fine – the Antarctic had a thriving and diverse marine community – and the next, it wasn’t. Clearly, a very sudden and catastrophic event had occurred on Earth,” said James Witts, a PhD student in the University of Leed’s School of Earth and Environment and lead author of the study, in a press release.
