The Cenozoic Era

The Cenozoic Era

What was the world like?

Major event

During the paleogene period the weather was warm with tropical conditions, during the neogene period the weather was still cool, grasslands were expanding and the seasonal changes were more noticable. The quaternary period fluctuates with glaciation and interglacial periods due to inconsistent weather patterns with global warming. There were many more mammals during this era with primates, early mammals, large herbivores, birds, and marine life was florishing with whales, dolphins, and marine biodiversity.

At the end of the Pleistocene Epoch there was a mass extinction that marked the end of the last ice age. This caused for many mam mals like wooly mamoths, sabertoothed tigers, and giant sloths to become extinct. Following this was the evolution of mammals and birds. After dinosaures became extinct, mammals diversified into many different forms like primates, whales and herbivores.
