While the Tertiary began with a biosphere in
ruins
, it recovered. Mammals became dominant and humanity evolved to the genus of modern humans. The Tertiary began hot and humid and ended in an ice age. The current International Geological Timescale

What mammals lived during the Tertiary period?
These North American invaders included
dogs and wolves, raccoons, cats, horses, tapirs, llamas, peccaries, and mastodons
.
What were 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 lived in the Tertiary period?
During the tertiary period, mammals diversified rapidly. Some examples were bears,
hyenas
, insectivores, whales, dolphins, walruses, rabbits, monkeys, apes, lemurs, hippopotamus, hoofed mammals, early mastodons, seals, horses, rhinoceros, rodents, oreodonts, and humans ( Australopithecus).
What major event happened in 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. This event formed the Cretaceous-Tertiary, or K-T, boundary.
How many years did the Tertiary period last?
Tertiary Period, former official interval of geologic time lasting from
approximately 66 million to 2.6 million years ago
.
What dangers are in the tertiary period?
The cooling of global temperatures
. The rise of mammals as the planet’s dominant vertebrate. Many earthquakes and volcanic eruptions. Ends with the Ice Age.
What era is the Quaternary period in?
The Quaternary Period is
the third and last of the three periods of the Cenozoic Era
. You and I are living in this period, which began only 2.58 million years ago. This is less than 0.1% of all of geologic time! A thin layer of sediments deposited during the Quaternary covers much of the Earth’s land surface.
What time period is today?
We live in
the Holocene Epoch
, of the Quaternary Period, in the Cenozoic Era (of the Phanerozoic Eon).
What happened during the Oligocene period?
The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included
a global expansion of grasslands, and a regression of tropical broad leaf forests to the equatorial belt
.
What is unique about the Tertiary period?
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.
