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).
What else can I help you with?
Did humans live during the tertiary period?
The Tertiary period happened after the extinction that took place during the Cretaceous period, so mammals saw a great diversification, the most notable of which was the movement from eating from trees to eating grass. Along with these mammals, birds also became the dominant animals in land ecosystems.
What is meaning Tertiary Boundary?
A boundary is a borderline, a separation between two things or the edge of something. Tertiary means third. In this case the 'Tertiary Boundary' has a geological meaning. It is an horizon in the Earth's rock sequence that marks the end of the 'Tertiary Period' at the end of the 'Cretaceous' and the begiining of the 'Quaternary Period' - a point in time in Earth's history some 65.5 million years ago. It is also the time when the Dinosaurs became extinct.
When did the Cretaceous Tertiary extinction occur?
About 65.5 million years ago. The Cretaceous and Tertiary are geological time periods either side of this event. The event is significant because there was a large mass extinction event at this time including the extinction of all non avian dinosaurs. Most experts agree that the cause of the extinction was a asteroid impact.
What type of rocks existed during the tertiary period?
During the Tertiary period, a variety of rocks were formed, including sandstone, shale, limestone, and volcanic rocks such as basalt and andesite. The Tertiary period was characterized by changes in climate and tectonic activity, leading to the formation of diverse rock types in different environments.
When did the tertiary period start and end?
The Tertiary Period began roughly 65 million years ago following the mass extinction event that ended the Cretaceous Period. It ended about 2.6 million years ago, marking the beginning of the Quaternary Period.
Was the k-t extinction in the Tertiary period?
The k-t extinction was ~65million years ago and marks the transition from the Cretaceous to the Tertiary period.
What is the K-T extinction?
The k-t extinction marks the transition from the cretaceous to the tertiary period in which it is hypothesized that a meteorite struck the Earth and caused a mass extinction.
Is the Jurassic period a geologic time that followed the mass extinction of dinosaurs?
No. The Jurassic was in the middle of the dinosaurs' reign on Earth. The time period after the extinction of the dinosaurs is referred to as the Paleogene or the Tertiary.
Did humans live during the tertiary period?

What did earths surface look like in the tertiary period?
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.
When did the tertiary period start and end?
The Tertiary Period began roughly 65 million years ago following the mass extinction event that ended the Cretaceous Period. It ended about 2.6 million years ago, marking the beginning of the Quaternary Period.
What were some examples of the mammals of the tertiary period?
All mammals present today are example of tertiary period mammals as we are living in tertiary period .
What are the dominant organisms or the tertiary period?
During the Tertiary Period the dominant organisms were mammals. These mammals included the many different types of dinosaurs that were roaming the earth 65 million years ago. Other organisms included bony fish such as bass and trout, flowering plants, insects, and birds.
