A random fact that I love is...
Did you know that the K-T extinction event is named after the boundary between the Cretaceous and Tertiary periods in the geologic timescale? This boundary is marked by a thin layer of sediment that contains high levels of the element iridium, which is rare in the Earth's crust but common in asteroids and comets. This evidence supports the theory that an asteroid impact caused the extinction of the dinosaurs.
