At the beginning of the period mammals replaced reptiles as the dominant vertebrates. Each epoch of the Tertiary was marked by striking developments in mammalian life. The earliest recognizable hominoid relatives of humans, Proconsul and Australopithecus, appeared. Modern types of birds, reptiles, amphibians, fish, and invertebrates were either already numerous at the beginning of the period or appeared early in its history. Modern families of flowering plants evolved. Marine invertebrates and non-mammal marine vertebrates experienced only modest evolution.

Continental drift was modest. Gondwana finally split completely apart, and India collided with the Eurasian plate. South America was connected to North America toward the end of the Tertiary. Antarctica -- which was already separate -- drifted to its current position over the South Pole. Widespread volcanic activity was prevalent. Climates during the Tertiary slowly cooled, starting off in the Paleocene with tropical-to-moderate worldwide temperatures and ending up with extensive glaciations at the end of the period.

The term Tertiary was first used by Giovanni Arduino in the 1700's. He classified geologic time into primitive (or primary), secondary, and tertiary periods based on observations of geology in northern Italy. Later a fourth period, the Quaternary, was applied. 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. He used Greek names: Eocene, Miocene, Older Pliocene and Newer Pliocene. Although these divisions seemed adequate for the region to which the designations were originally applied (parts of the Alps and plains of Italy), when the same system was later extended to other parts of Europe and to America it proved to be inapplicable. Therefore, later the use of mollusks was abandoned from the definition and the epochs were renamed and redefined. With current terminology, what was called the Tertiary began at the start of the Paleocene and lasted through the end of the Pliocene. Giovanni Arduino (Caprino Veronese, October 16, 1714 – Venice, March 21, 1795) was an Italian geologist who is known as the Father of Italian Geology. ...

Tertiary - Wikipedia, the free encyclopedia (444 words)
Tertiary period was previously one of the major divisions of the geologic timescale, from the end of the Cretaceous period about 65 million years ago to the start of the Quaternary period about 1.6 million years ago.
The Tertiary covers roughly the time span between the demise of the dinosaurs and beginning of the most recent ice age.
Climates during the Tertiary slowly cooled, starting off in the Paleocene with tropical-to-moderate worldwide temperatures and ending up with extensive glaciations at the end of the period.
Post-secondary education - Wikipedia, the free encyclopedia (249 words)
Post-secondary or tertiary education, also referred to as third-stage, third level education, or higher education, is the non-compulsory educational level following the completion of a school providing a secondary education, such as a high school, secondary school, or gymnasium.
Tertiary education is normally taken to include undergraduate and postgraduate education, as well as vocational education and training.
Tertiary education generally results in the receipt of certificates, diplomas,or academic degrees.
