The Day the Mesozoic Died

In the video I watch, they talked about many things. One thing they talked about was that if an asteroid that was 10 kilometers deep landed on a sea or an island, it would displace incredible amounts of rock and water, that can cause tsunamis. The scientists took rock examples to use in the lab that showed all the signs of a high energy impact. This made everyone believe that there was a big crater buried on the peninsula. Later they named the crater the Chicxulub crater. 

When you crack open rocks you can see the leaves on plants and can tell what insects ate them. Fossils fill the whole place, which describes uniformitarianism which says that things in the past also happen today, which fossils do. Scientists found a boundary they named the KT boundary, which can tell the age of fossils. This boundary helped determine where many things lived because they can tell where in comparison they were from the boundary.

Smoke from fires later filled the air, as long as sulfur that exploded in the air, the Mesozoic era, the life of dinosaurs was over.  This wrecked over 60 percent of plant life. The asteroids were very bad within life back then. Many disasters occurred and many things died down.
