Hum,
Here is a strewnfield of craters around Lake Chiemsee, in south-east Bavaria, that
may have been caused by fragments of a huge comet that broke up in the Earth’s atmosphere.
Evidence from ancient tree rings and Roman reports of “stones falling from the sky”, has led researchers to conclude that the impact happened in about 200BC.

47.8° to 48.4° N and 12.3° to 13.0° EThe crater field was uncovered after amateur archaeologists working in the area found pieces of metal containing unusual minerals.
More than 80 craters were found in an elliptical area 36 miles long and 17 wide, ranging in size from 10 to 1,215 feet across. The largest, filled with water, now formed Lake Tuttensee.
Around the site the team found clues that suggested an impact from space, including rock heated into glass and minerals associated with meteorites.
The most likely cause was a low-density comet, 1.1 kilometres wide, that broke up at an altitude of 43 miles and fell in pieces to Earth.
"[i]The main mass of the projectile struck the ground at 2,200 miles per hour, releasing an amount of energy equivalent to 106 million tons of TNT/i]"
Er, or not.
