Varying in size from one to several thousand acres, and measuring from 164 feet (50 m) to 6.8 miles (11 km) across, as many as 2½ million of these oval depressions scar the landscape from Florida to New York to Texas.
Millions of fireballs, about 1300 degrees F, with the blast waves. Could any living thing survive in the foot print?
The Gothenburg Magnetic Excursion in a broad sense ranges from 13,750 to 12,350 years BP and ends with the Gothenburg Magnetic Flip at 12,400−12,350 years BP (= the Fjärås Stadial in southern Scandinavia) with an equatorial VGP position in the central Pacific. The Gothenburg Magnetic Flip is recorded in five closely dated and mutually correlated cores in Sweden. In all five cores, the inclination is completely reversed in the layer representing the Fjärås Stadial dated at 12,400−12,350 years BP. The cores were taken 160 km apart and represent both marine and lacustrine environments. The Gothenburg Magnetic Flip represents the shortest excursion and the most rapid polar change known at present. It is also hitherto the far best-dated paleomagnetic event. The Gothenburg Magnetic Excursion and Flip are proposed as a standard magnetostatigraphic unit.

the great majority of extinctions in Afro-Eurasia and the Americas occurred during the transition from the Pleistocene to the Holocene epoch (13,000 BCE to 8,000 BCE).
The Quaternary period saw the extinctions of numerous predominantly megafaunal species
The most common thresholds used are weight over 40 kilograms (90 lb)[1] or 44 kilograms (100 lb)[2][3] (i.e., comparable or larger in mass than a human)
Anything as larger or larger than humans.
