In the Tertiary period, which epoch comes after the Miocene?

Paleocene
Pliocene
Eocene
Oligocene

The correct answer is: Pliocene

The Tertiary period is divided into several epochs that sequentially represent important geological and evolutionary developments. Following the Miocene epoch, which is known for significant changes in flora and fauna and the rise of mammals and birds, the next epoch is the Pliocene. The Pliocene epoch is characterized by considerable shifts in climate and geography, leading to the further evolution of the modern flora and fauna we are familiar with today. This epoch is marked by the continuing development of the Earth's landscapes and the adaptation of species to changing environmental conditions. The other epochs, such as the Paleocene, Eocene, and Oligocene, occurred before the Miocene in chronological order. They represent earlier stages of mammalian evolution and biodiversity development, making them incorrect choices in this context. The sequence of the epochs within the Tertiary period illustrates a timeline of evolutionary progress, with the Pliocene being the direct successor to the Miocene.
