Phys.org reports that "Scientists find proof that an asteroid hit the North Sea more than 43 million years ago." Per the article, new evidence has confirmed that the Silverpit Crater in the southern North Sea was caused by a comet or asteroid impact 43 to 46 million years ago. "The Silverpit Crater sits 700 meters below the seabed in the North Sea, about 80 miles off the coast of Yorkshire," the article relates, and is 3 km wide and surrounded by a 20 km wide zone of circular faults. I suspect that these large impacts have happened far more often than scientists suspect.
