The Silverpit crater is a crater located in the North Sea off the
coast of the United Kingdom. It was discovered in 2002 during the
analysis of seismic data collected during routine exploration for oil,
and was initially reported as the UK's first known impact crater.
However, alternative origins have subsequently been proposed. Its age
is thought to be of the order of 65 million years, making its
formation roughly coincident with the impact that created the
Chicxulub Crater (KT boundary). If Silverpit is indeed an impact
crater, this may imply that the Earth was struck at that time by
several objects, possibly in a similar event to the collision of Comet
Shoemaker-Levy 9 with Jupiter in 1994. Several other impact craters
around the world are known to date from roughly the same epoch,
lending credence to this theory.
