During the Cenozoic era, mammals diversified significantly, evolving into a wide range of forms and sizes. This period saw the emergence of many modern mammal groups, including primates, cetaceans (whales and dolphins), and large herbivores like elephants and rhinos. Additionally, birds also diversified during this era, adapting to various ecological niches. The Cenozoic is often referred to as the "Age of Mammals" due to this remarkable diversification.
