What was the Tertiary period known for?

What are the characteristics of life during Tertiary Period?
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.
What types of plants were in the Tertiary period?
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?
The Tertiary Period began abruptly when a meteorite slammed into the earth, leading to a mass extinction that wiped out about 75 percent of all species on Earth, ending the reptile-dominant Cretaceous Period and Mesozoic Era. The Tertiary began hot and humid and ended in an ice age.
What makes the Tertiary Period unique?

When did the tertiary period start and end?
What are Tertiary deposits?

When was the Tertiary period of the Cenozoic era?
In geologic time , the Tertiary Period (also sometimes referred to in terms of a Paleogene Period and a Neogene Period), represents the first geologic period in the Cenozoic Era . The Tertiary Period spans the time between roughly 65 million years ago (mya) and 2.6 mya.
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?
In 1828, Charles Lyell incorporated a Tertiary Period into his own, far more detailed system of classification. He subdivided the Tertiary Period into four epochs according to the percentage of fossil mollusks resembling modern species found in those strata.
