How do you know a mass extinction actually did occur?
No evidence of the extinct lifeforms appears in the stratigraphic record immediately following the extinction event.
What does KT mass extinction mean?
The mass extinction that is believed to have eliminated larger dinosaurs 65 million years ago. Smaller dinosours survived, their descendants are today's reptiles. The mass extinction is believed to have been caused by an asteroid that collided with Earth.

Why do you think most extinction's occur as background extinctions?
Most extinctions occur as background extinctions because they are longer time periods unlike the shorter mass extinctions which there were only two in the Paleozoic era, the Ordovician mass extinction, and the Permian/Triassic extinction in which 95% of all marine animals became extinct
When did the mass extinction that killed dinosaurs occur?
In the Late Cretaceous (65 million years ago).

What evidence of the KT boundary in Colorado has been discovered by researchers?
Researchers have found evidence of the KT boundary in Colorado, including a layer of sediment containing high levels of iridium, shocked quartz, and microtektites. These materials are characteristic of the impact event that caused the mass extinction of the dinosaurs.
