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.
Did the K-T extinction occur before or during the Tertiary period?
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.
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.
How do you use cretaceous- tertiary extinction in a sentence?
A meteorite impacted Earth and caused the cretaceous-tertiary extinction.
What did the Cretaceous - Tertiary extinction event end?
The Tertiary Era.
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 is meaning Tertiary Boundary?
The Tertiary Boundary, also known as the K-T Boundary, marks the end of the Cretaceous Period and the beginning of the Tertiary Period in the geologic timescale. It is characterized by a mass extinction event that led to the extinction of the dinosaurs and many other species. The impact of a large asteroid is believed to have played a significant role in causing this mass extinction.
What is the KT asteroid?
It is the asteroid that hit the Earth 65 million years ago and contributed to the extinction of the dinosaurs. It impact crater is located in Chicxulub which is in the Yucatan peninsula, it is buried deep underground. KT refers to the geological transition between the Cretaceous and the Tertiary periods. (Cretaceous in German starts with a K)
How do you use tertiary in a a sentence?
A meteorite impacted Earth and caused the cretaceous-tertiary extinction.
When did the Cretaceous Tertiary extinction occur?
The Cretaceous-Paleogene extinction event, also known as the K-T extinction, occurred around 66 million years ago. This event led to the extinction of the dinosaurs and many other species, marking the end of the Cretaceous period and the beginning of the Paleogene period.
What is the K-T boundary?
The K-T boundary, also known as the Cretaceous–Paleogene boundary, is a geological boundary marking the end of the Cretaceous period and the beginning of the Paleogene period. It is marked by a mass extinction event that wiped out non-avian dinosaurs and many other species around 66 million years ago. The impact of an asteroid or comet is believed to have played a significant role in this mass extinction event.
Why did the microraptor become extinct?
The microraptor existed during the early Cretaceous period. It became extinct following the KT extinction event, which wiped out the majority of life on earth.
