Where was North America during the tertiary Period?

Tertiary exposures are also bundant in Western Mexico and the Yucatan, as well as in several western Canadian provinces.
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.
Which is called tertiary sector?
The tertiary sector of the economy, generally known as the service sector, is the third of the three economic sectors of the three-sector theory, (also known as the economic cycle). Services (also known as “intangible goods”) include attention, advice, access, experience, and affective labor.
