The End-Ordovician Extinction was the first of the so-called ‘Big Five’ mass extinctions in the history of life on Earth - more than 80% of species in the oceans died out. But could you ...

But the first major mass extinction was way before that – about 443 million years ago. It’s called the Late Ordovician mass extinction. Back then, most living things were in the ocean.

Instead, the team hypothesized a stellar explosion may have been a potential factor in the Late Devonian extinction event 372 million years ago and one at the end of the Late Ordovician 445 ...

Get Instant Summarized Text (GIST) At least two mass extinction events in Earth's history, the late Devonian and Ordovician, may have been caused by nearby supernova explosions.

Sharks showed up just in time for the end of the world, appearing just 10 million years before the End-Ordovician extinction. Those earliest sharks were probably toothless and wouldn’t ...
