What is the K-T boundary?
The geographical line of Pangea that denoted dinosaur habitats.
The point in time when dinosaurs became extinct.
A popular theory that explains the extinction of dinosaurs at the K-T boundary -- the Alvarez theory -- states that an asteroid may have hit the Earth, causing massive shock waves, debris clouds and devastation. That impact, combined with geological changes and volcanic eruptions, most likely led to extinction of dinosaurs and about 50 percent of other species on Earth.
The geographical point that paleontologists use to map where dinosaur fossils are found.
