Here's More Evidence That Earth Got Hit by Something Huge 12,800 Years Ago
By George Dvorsky on 06 Oct 2019 at 6:00AM
New evidence from South Africa is adding further credence to the idea that a large asteroid or comet struck Earth during the Pleistocene – an event that possibly triggered the extinction of many large animals while also disrupting human populations at a global scale.

“Our finding at least partially supports the highly controversial Younger Dryas Impact Hypothesis,” explained Thackeray in a press release. “We seriously need to explore the view that an asteroid impact somewhere on Earth may have caused climate change on a global scale, and contributed to some extent to the process of extinctions of large animals at the end of the Pleistocene, after the last ice age.”

@Gefn 

This is fairly recent, in terms of earth's history.

After the last ice age?

We are still in the last ice age. We're just in a interglacial period in this ice age.

I would wager that with the extinction of every megafaunal assemblage there was some sort of cosmic event. Paleocene, Pliocene, Miocene, Oligocene, Eocene, and Pleistocene periods are marked by changes in the critters, and likely either volcanic eruptions of incredible proportions or cosmic impacts as well.  While the Cretaceous/Tertiary boundary has been studied for this, have the others?
