Marquis impactor (The British Ain't Coming)

The English impactor, or more speculatively known as the English asteroid, was an asteroid or comet at least 6 miles (10 km) in diameter which created the English Crater. It impacted on a landmass in the North Atlantic Ocean, which was destroyed as a result of the collision. It is speculated that had the impactor missed the landmass, a series of isles would have developed north of present-day Normandy, France, dubbed the "English Isles" by scientists. The time of the impact is believed to be at the end of the cretaceous period, causing a mass extinction that led to the extinction of most dinosaurs.
