That's a neat article however,

Most widely-supported explanations (Dinosaur mass extinctions)

- Sea-level falls: 12, of which 7 were associated with significant extinctions.<sup id="wp-_ref-ii_1" class="reference">[19]</sup>
- Asteroid impacts producing craters over 100km wide: 1, associated with 1 mass extinction.
- Asteroid impacts producing craters less than 100km wide: over 50, the great majority not associated with significant extinctions.

We can't say for sure what happened, but to claim with such certainty that they were wiped out by only one of the theories theory is a bit unprofessional. (and dare I say....unscientific!)
Other then that It's a neat article.
