One animal is the Eohippus.
All mammals present today are example of tertiary period mammals as we are living in tertiary period .
Earth's geography changed dramatically between the beginning and the end of the Tertiary. I could give you a long winded description, but I think you would prefer maps. Under "Related Links" there will be a map for the early Tertiary (called the Paleogene), and one for the later Tertiary (Neogene). P.S. The Tertiary began 65.5 million years ago and ended 2.6 million years ago.
The "tertiary period" is not a place you can go to. It is a time period - in the remote past of Earth. Since it is in the past, you can't go there.
The k-t extinction was ~65million years ago and marks the transition from the Cretaceous to the Tertiary period.

the Apocalypse
During the Tertiary Period, the surface of the earth looked much like it does today. It was quite warm with periods of cold much like today.
The Tertiary Period (65.5 to 2.588Ma) is the informal name for the geological period that followed the K-T extinction event. So the K-T event happened before the Tertiary. In fact "K-T" is actually short for Cretaceous-Tertiary as it marked the end of the Cretaceous and the start of the Tertiary.The lower tertiary is more formally known as the Paleogene Period(65.5 - 23.03 Ma) and the upper Tertiary is more formally known as the Neogene Period(23.03 - 2.588Ma).
