Lesson Description

The Cretaceous–Paleogene (K–Pg) extinction event, which occurred 66 mya, caused the mass extinction of nearly 75% of the plant and animal species on Earth. This event is marked by a thin layer of sediment which can be found throughout the world in marine and terrestrial rocks. The boundary clay shows high levels of iridium, which is rare on Earth but abundant in asteroids.

Central Question: What evidence exists for the extinction of the dinosaurs and 75% of all animal and plant species at the end of the Cretaceous Period?

Instructional Objective: Coming Soon!
