The cretaceous period and the aftermath
The Cretaceous Period and the Aftermath
Imagine a great, thickly muscled dinosaur. Got it? See those serrated teeth? And the great yellow eye that is pondering whether you are food or foe? Now, imagine something that can kill this beast and all of its kind. This “something” is called the Cretaceous Tertiary Extinction event, and it occurred 65.5 million years ago, and killed all the dinosaurs, and affected the process of evolution forever afterward.
The Cretaceous Tertiary Extinction Event was actually a geologically short period of time. It is known as the K-T extinction event. It’s associated with the geological signature known as the K-T boundary. The K-T boundary is a thin band of sedimentation found in various parts of the world.
The thin band of sedimentation marking the K-T boundary line Did you know that the K stands for Cretaceous period? Guess someone didn’t know how to spell! The T stands for Tertiary period. This boundary marks the end of the Mesozoic Era, and it marks the beginning of the Cenozoic era. This was a large scaled mass extinction event. It may have been caused by one or more catastrophes.
On March 4, 2010, a panel of 41 scientists agreed that the Chicxulub asteroid triggered the mass extinction. Although, several impact craters such as in the Deccan Traps may have caused it. With such a catastrophic

Evolution occurred once organisms were formed. Our understanding of evolution does not depend on our non-understanding of how it began. Right now the scientists believe that complex life cam from simple chemical reactions. It is unclear how this happened, and scientists don’t understand how it happened. Not much is clear about the structure of the first living things and life. Also, there is no scientific consensus on how evolution began. But what we do
