This is the geographic distribution of the modern (left) and fossil (right) larger herbivore communities analyzed in the paper.

For most of the last two million years, the now-submerged continental shelves were dry land, not covered with ice for the most part, and warmer. Just sayin'.

There was a reboot 12,800 years ago in the Pleistocene Period by a comet or asteroid hitting Africa that wiped out most life there.
*Previous thread today.
Is there a conflict of theories?

Not a re-boot of the human species. Just a shock to the environment.

For all of these traits, they found that the makeup of ancient herbivore communities differed significantly from those of today. I don't want to be nearby when Greta Thunberg hears about this.

Greta probably thinks a herbivore is something from LIttle Shop of Horrors. And she's never seen the movie because of the sexist title.

Tell them to accept Impact Glaciation or we’ll unless a 1000 Greta Thornberg wannabees on them, but with more autism.

Of interest is that fact that 1 million years ago when the article says things began to change is also when the every 100,000 year Ice Age/warming pattern began. That ought to get some study.
To: SunkenCiv
so Climate Change has been going on for the last 5 million years at least?
Who would have guessed!

The herbivore fossil community in Ethiopia and Kenya looks like a perfectly traced line following the Great Rift Valley.
Is that meaningful or just a coincidence?
To: zeestephen
Noticed that as well. Water, water, everywere there is abundant life.

It was North American Ice sheet the rocks hit over a period of 1000 years. You misread the post yesterday which seemed to imply Africa, but that was only one minor deposit - most are found on the NA continent. There was no crater as the rocks hit a 2 km thick glacier. There is a possible crater in the UP of Michigan. Other ‘splatter’ impacted the Carolinas and Nebraska.
