10,700 BCE
- Atlantis is deluged by water, possibly from tsunamis caused by oceanic impact of a disintegrating comet or large asteroid, as reported by Plato (either historic or mythic). The location is possibly North and South America, resulting in extinction of about 30 species of large mammals. The great deluge may also be the source of the legends of the biblical Noah's Flood. Dated to this same period are remains of millions of animals in hundreds of miles of frozen tundra found in Alaska and Russia, and massive piles of mastodon and saber-toothed tiger bones in Florida, and various animals found quick-frozen Venezuela. Some 500,000 shallow basins from Georgia to Delaware in the USA also date to this period, suggesting a vast meteor shower of a disintegrating giant comet. Human deaths are estimated at multiple millions. [521]
3195 BCE

[521]

- A 1.1km comet impacts southeastern Bavaria (modern day Germany), probably breaking up 70km above the Earth's surface, creating a field of meteorites and impact craters. At about the same time Roman authors write about showers of stones falling from the skies, terrifying the populace. [521]
44 BCE (approximate)
- A daylight comet passing close to the Earth creates a dust veil over Italy, possibly from large fragment impacts. [521]

536
-
- The sky darkens for about 18 months, crops fail throughout Europe. Over ten years, the population of Rome drops by one-third, Constantinople by four-fifths. Environmental degradation observed from Great Britain to China. Likely cause is overhead cometary explosions. [521]
580
-
- In Louraine, a great light is seen crossing the sky, falling to Earth with a crash heard across the countryside. The city of Bordeaux is shaken by an earthquake, villages are burned down, the city of Orleans is burned in a great fire. [521]
