Regarding the North Dakota discovery, that a fossil bed of many animals killed within one hour of the asteroid impact was discovered, is truly one of the most jaw dropping paleontological discoveries of our lifetimes.
The Greenland crater, which may be the Younger Dryas impactor. Time will tell, it will be dated:

TY . If they can nail it down to the last ice age, that would explain almost everything! Yes the impact that covered the extinction level event is important , as well as the find. I’m more interested in the end of the last ice age, the Clovis people and megafauna event. Also the emergence of the Folsom culture as it has now been shortened from 500 years to 400. To me that new number is substantial ! Again, thanks for the video as I will try to keep up with any new info .....JJLubbock County Tx

Crazy find. I wonder if this will change Greta Keller's mind. She has been arguing against the asteroid theory for decades now. Not sure she rejects an impact but claims volcanoes did in the dinos.Central Ohio

The asteroid theory for the cause of the extinction event is not universally accepted, and volcanoes are supported by some. It's not a settled debate, and, for that matter, many scientists will want to independently visit and examine this North Dakota site to see for themselves.

I’ve got to submit that a impact such as that could have triggered volcanic events ! This would include both theories into a dramatic situation !

Yes, the impact triggered volcanic activity, but she insists there were years and years of heavy volcanic ash falling before the impact and that life was declining everywhere for an extended period of time before the impact. Interesting idea, but Keller seemed like she would take any criticism personal. Her rejection of other ideas if valid rubs me the wrong way. Who knows, she could be right, some of her points seem valid. Marine sediment records. Was probably a combination of things and hopefully more finds like this will help decide the matter.

Being such a large event, I'm surprised other similar spots haven't been discovered, considering the displacement of mud on that large of a scale, then baking it essentially.Central Ohio
