Cretaceous–Tertiary_extinction_event
The Cretaceous–Tertiary extinction event, which occurred approximately (Ma), was a large-scale mass extinction of animal and plant species in a geologically short period of time. Widely known as the K–T extinction event, it is associated with a geological signature known as the K–T boundary, usually a thin band of sedimentation found in various parts of the world.
