The K-T extinction occurred at the boundary between the Cretaceous and Paleogene periods, marking the end of the Mesozoic Era and the beginning of the Cenozoic Era. Therefore, it occurred at the end of the Cretaceous period and before 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.
During the Tertiary period, the geography included the separation of continents, the uplift of the Himalayas and the Alps, and the formation of the Atlantic Ocean. Climate was generally warmer, with forests expanding and new plant and animal species evolving. The Tertiary period lasted from about 65 million years ago to 2.6 million years ago.
Miocene
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.
All mammals present today are example of tertiary period mammals as we are living in tertiary period .
During the Tertiary period, Earth's continents were continuing to drift apart due to plate tectonics. This movement led to the formation of new mountain ranges and the reshaping of landmasses. The configuration of the continents during this time was closer to their current positions compared to earlier periods.
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.

pleiocene
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 K-T extinction occurred at the boundary between the Cretaceous and Paleogene periods, marking the end of the Mesozoic Era and the beginning of the Cenozoic Era. Therefore, it occurred at the end of the Cretaceous period and before the Tertiary period.
The Tertiary Period (including the Pliocene, Miocene, Oligocene, Eocene, and Paleocene Epochs) lasted from about 65 million years ago to 1.8 million years ago. It is part of the Cenozoic Era, along with the Quarternary Period.
