K–T extinction, abbreviation of Cretaceous–Tertiary extinction, also called K–Pg extinction or Cretaceous–Paleogene extinction, a global extinction event responsible for eliminating approximately 80 percent of all species of animals at or very close to the boundary between the Cretaceous and Paleogene periods, about 66 million years ago.
KP Extinction Layer Sample. Great for dinosaur enthusiasts! The Cretaceous-Paleogene (K-Pg) extinction event, also known as the Cretaceous-Tertiary (K-T) extinction , was a sudden mass extinction of three-quarters of the plant and animal species on Earth, approximately 66 million years ago.
Topic 2: Case study, the K/T extinction K/P Extinction is also known as the Cretaceous/Tertiary Extinction (K/T) Describe the character of extinctions at the K/T boundary At the end of the Cretaceous, many creatures, including the dinosaurs, went into extinction . o In this unit we will examine the nature of and possible causes of this K/P, The End of the Dinosaurs: The K-T extinction Almost all the large vertebrates on Earth, on land, at sea, and in the air (all dinosaurs, plesiosaurs, mosasaurs, and pterosaurs) suddenly became extinct about 65 Ma, at the end of the Cretaceous Period.
