This period began 65 million years ago and ended roughly 1.8 million years ago and bore witness to some major geological, biological and climatological events. This included the current configuration of the continents, the cooling of global temperatures, and the rise of mammals as the planet's dominant vertebrates.

What events happened during 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. This event formed the Cretaceous-Tertiary, or K-T, boundary.
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 life existed during Tertiary period?
The Tertiary witnessed the dramatic evolutionary expansion of not only mammals but also flowering plants, insects, birds, corals, deep-sea organisms, marine plankton, and mollusks (especially clams and snails), among many other groups.
Which among the following mountains were formed during Tertiary period?
The correct answer will be Alpine Mountains.
What event triggered the emergence of large mammals in the Tertiary Period?
The rapid evolutionary diversification or radiation of mammals in the early Tertiary was probably mostly a response to the removal of reptilian competitors by the mass extinction event occurring at the end of the Cretaceous Period.
What is the meaning of tertiary activity?
The tertiary sector covers a wide range of activities from commerce to administration, transport, financial and real estate activities, business and personal services, education, health and social work. It is made of: ... the non-market sector (public administration, education, human health, social work activities).
Why was the Tertiary Period renamed?
He subdivided the Tertiary Period into four epochs according to the percentage of fossil mollusks resembling modern species found in those strata. ... Therefore, the use of mollusks was abandoned from the definition and the epochs were renamed and redefined.
What are tertiary landforms examples?
The tertiary landforms refer to a period that was two hundred million years ago formed by the Gondwana deposits with the extinction of dinosaurs which was an integration of period of Paleogene and Neogene also known as the Lower Tertiary and the Upper Tertiary.
How was the plant life during 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 killed the dinosaurs?
The asteroid impact led to the extinction of 75% of life, including all non-avian dinosaurs. The crater left by the asteroid that wiped out the dinosaurs is located in the Yucatán Peninsula. ... It is called Chicxulub after a nearby town.
What did the world look like during dinosaurs?
All continents during the Triassic Period were part of a single land mass called Pangaea. This meant that differences between animals or plants found in different areas were minor. The climate was relatively hot and dry, and much of the land was covered with large deserts. Unlike today, there were no polar ice caps.
What is the Cretaceous period known for?
The Cretaceous was a period with a relatively warm climate, resulting in high eustatic sea levels that created numerous shallow inland seas. These oceans and seas were populated with now-extinct marine reptiles, ammonites, and rudists, while dinosaurs continued to dominate on land.
