The Cenozoic era happened 65 million years ago. This is the third of the Earth's time period. The climate during this time is still warmer than it is today, but things have been thrown off a little by human ways. The continents started pulling apart creating bigger areas for the ocean. Many of the mountains we see today were formed during this time period. Soon the climate started cooling down and the huge forrest were decreasing. The species that died during this period are the Champsosaurs which were crocodile like animals and K-T.
