[ tûr′shē-ĕr′ē ]

Noun

Tertiary. The first period of the Cenozoic Era, from about 65 to 2 million years ago. During this time the continents took on their present form, and the climate changed from being warmer and wetter, in the early part of the period, to being drier and cooler in the later part. Mammals replaced dinosaurs as the dominant form of terrestrial animal life, and many modern types of flowering plants, insects, mollusks, fish, amphibians, reptiles, and birds appeared. The Tertiary is subdivided into the Paleogene and the Neogene, although these terms are not as widely used as are the names of the epochs that constitute them. See Chart at geologic time.

Adjective

Relating to or having a carbon atom that is attached to three other carbon atoms in a molecule.
Relating to an organic molecule, such as an alcohol, in which the functional group is attached to a tertiary carbon.
