It is subdivided into the Palaeocene, Eocene, Oligocene, Miocene, and Pliocene epochs in ascending order. The Tertiary period was characterized by the rise of the modern mammals and the development of shrubs, grasses, and other flowering plants.

The Paleocene epoch marks the beginning of the Cenozoic era and the Tertiary period. Dense forests grow in the warm, damp, and temperate climate. Ferns, horsetails, and shrubby flowering plants make up the underbrush, while sequoias, pines, and palms grow tall, some to towering heights.
What is unique about the Tertiary period?

What kind of animals lived in the Tertiary period?
In the first epoch of the Tertiary, the Paleocene (65-55 million years ago), mammals still consisted of survivors from the Cretaceous, including the monotremes , primitive egg-laying mammals. Condylarths, the ancestors of the ungulates , or hoofed animals, were widely present in the Paleocene.
How did Charles Lyell classify the Tertiary period?
