Did the K-T extinction occur before or during the Tertiary period?
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 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.
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 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)
What is the KT boundary 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.
What is the K-T boundary?
The KT Boundary (also called the Cretaceous-Paleogene, or K-Pg boundary) is a boundary marking the Cretaceous-Tertiary extinction (KT extinction) event. It is usually seen as a thin band, caused by an asteroid impact that wiped out much of life at the time.
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.
Element traced to the extinction of the dinosaurs?
The KT boundary has a spike in Iridium concentrations.
