Shoemaker-Levy 9 was a comet that hit Jupiter a few years ago. Here is a link: http://www.jpl.nasa.gov/sl9/
According to the site, there were 21 discernable pieces and the collisions lasted for about 7 days.
Relating Silverpit and Chicxulub wouldn't be a very large stretch of the imagination.
As a side note, has anyone ever heard of, or read a study on the ages of the Moon craters?
