The Tertiary period is the beginning of the Cenozoic Era. It began 65 million years ago and ended 1.8 million years ago.
The Cenozoic era is divided into the Tertiary and Quaternary periods. The Tertiary period is from 65 million years ago until 2 million years ago and the Quaternary period is from 2 million years ago to the present.
The Tertiary is a term for a geologic period 65 million to 2.588 million years ago.
The k-t extinction was ~65million years ago and marks the transition from the Cretaceous to the Tertiary period.
65 million to 1.8 million years ago.
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 Miocene Epoch, 23.8 to 5.3 million years ago. = =
The Tertiary lasted from 65.5 million years ago until 1.8 million years ago. Saber toothed cats evolved about 28 million years ago and died out 10,000 years ago. Therefor, saber toothed cats did live in the Tertiary.
The answer is 63.2 million years. Since the Tertiary Period began 65 million years ago and then stoped 1.8 million years ago you have to subtract the 1.8 million from 65 million to get the actual lenght of time.
The Oligocene Epoch is in the Paleogene Period, coming before the Eocene Epoch. (previously considered as the Tertiary Period, which overlapped the Neogene and Paleogene) It was about 34 to 23 million years ago.
there was 5 epoch in the tertiary period
