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).

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 are mass extinction and background extinction different?
Mass extinction - More than 50% of the population went extinct in a short period of time.Background extinction - An average rate of extinction occurred during a given time period.
Fossil of dinosaurs are found in Cretaceous rock but not in tertiary rock?
All dinosaurs went extinct before the tertiary period.
What period did the dinosaurs become extinct?
Around the end of the Cretaceous Period.Dinosaurs became extinct at the end of the Mesozoic Era 65 million years ago. Their extinction also marked the beginning of the Cenozoic Era.Dinosaurs disappeared near the end of the cretaceous period.Most people believe it was at the end of the Cretaceous however the truth is that it ended in the Tertiary PERIOD not era so be careful that was why the event was called the K-T event because c had been taken in a mass extinction in the oceans.All non avian dinosaurs lived in the Mesozoic Era (251 - 65Ma). The mass extinction 65 million years ago of all non avian dinosaurs along with many other types of animals and plants marks the boundary between the Mesozoic and the Cenozoic Eras.
Is the Cenozoic era before or after dinosaur extinction?
Yes, the Cambrian Period was before the Mesozoic Era
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.

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.

During which period the dinosaurs disappeared on the Earth?
The Cretaceous / Tertiary boundary (KT) occurred 65 million years ago and extinctions of most dinosaurs was probably due to a meteorite impact in the Yucutan peninsular of Mexico known as the Chixulub crater.
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 .
Is the Cenozoic era before or after dinosaur extinction?
Yes, the Cambrian Period was before the Mesozoic Era
