Описание:
Scientists believe two major events resulted in this extinction: glaciation and falling sea levels.86% of life on Earth was wiped out.Trilobites, brachiopods, and graptolites died off in large numbers but interestingly, this did not lead to any major species changes during the next era.Добавлено на ленту времени:
