South America finally met up with North America with the completion of formation of the Central American isthmus, which was about 5 million years ago (process started roughly 7 million years ago, and finished after a while). This resulted in the cutting off of major equatorial oceanic current between the Atlantic and Pacific Oceans, resulting in a drastically cooling effect on the planet as a whole.

- The Andean-Saharan, A minor ice age occurred from 460 to 430 million years ago, during the Late Ordovician and the Silurian period.
