This not only explains the large-scale extinction, it’s probably the source of the Great Flood myths around the world. If as they believe the comet made a number of impacts on the arctic ice cap, sea level would have risen almost 400 feet almost overnight.

Isn’t this around the time of the quick-frozen Beresovka mammoth?

There is a cave in Florida, now under water that they have found ashes of a campfire and burnt bones from animals of the time.....................

The Gulf of Mexico looks like a giant water filled impact crater

The flood stories more closely correlate with events of 7000 years ago when the rising sea levels flooded the north sea, the baltic sea and the black sea.

Kinda stupid to call it myth and then state 400 foot water rise..

Just saying

The problem with this story is that the previous ice age lasted around 80,000 years before it ended. It was shortly after that when the asteroid hit. So then, how did these animals survive the ice age, only to become extinct after just a short period of warming?

The data I’ve seen is that the Younger Dryas cold was no worse than the worst of the ice age.

Plausibly, the earlier Ice Age was due to relatively slow cyclical changes in earth’s orbit that permitted adaptation and survival. A more abrupt transition due to a comet or asteroid impact like the Younger Dryas would have been more challenging.

Sounds kinda like Worlds in Collision is a book by Russian-American independent scholar Immanuel Velikovsky published in 1950. The book postulates that around the 15th century BC, the planet Venus was ejected from Jupiter as a comet or comet-like object and passed near Earth (an actual collision is not mentioned). wiki

No, it was global warming caused by these:



At least the carpooled, though.

It was probably in Canada. The resulting deluge caused the glaciers to melt and run south into Baja and the Gulf of Mexico.

It also caused ice dams to form near the Black Sea, which ultimately burst, washing down through the Middle East.

The black mat exists from California to Belgium and down to South America which is evidence of a massive firestorm in North America following the impact. The non burrowing animals in the open probably perish immediately while some small groups in protected valleys may have survived but the food source was gone for a couple of seasons for sure.

According to the Book of Revelation there will be an impact by an asteroid or comet that will make the waters of the earth poisonous. Some comets are completely composed of cyanide. That’s the way I interpret it anyway.

All you have to do is look at the Krakatoa explosion in 1883 to know that very easily things can happen to change global climate both either from the earth or something hitting the earth There was also periods in the 1450s they called a year without a summer because of another volcano 🌋 explosion

What happens after an extensive volcanic eruption?
Lots and lots of ash thrown into the atmosphere.
When Mt St Helens erupted, day light turned to night light in the surrounding areas. The museum near Mt St Helens has great videos showing all the aftermaths from the eruption.

Ditto when Krakatoa erupted in SE Asia, the darkening effect lasted long time. Which then leads what would happen if a giant asteroid big enough to cause crater the size of Gulf of Mexico. Yeah a nuclear winter lasting months. Those large Dinosaurs were cold blooded animals like Crocs are. They become immobile with cold. They had no energy to hunt for food. Thus they may have just starved to death.

The small mammals of that era on the other hand were warm blooded animals and can regulate their body temp better and many survived. Try this experiment. Place a gecko lizard in a jar (those are ubiquitous here in Florida and they eat insects and have no teeth and are cute) and place the jar in your fridge. Then catch a mouse and do the same thing. The cold blooded gecko will lie immobile and asleep. The mouse will be awake and respond to opening the fridge. That is the difference between cold blooded and warm blooded animals.

It cooled more quickly than the grasslands they needed to survive could move south.

When the big herbivores died, so did the predators, including many humans.
