The Late Devonian Mass Extinction wiped out as much as 45% of all life. Corals were almost wiped out completely.Giant armored fish vanished forever, but sharks living today have hardly changed from this time. The cause of the extinction is believed to be changing sea levels or salinity in the oceans changed. During the this period fish had crawled on land to become amphibians and the first trees appeared.
