[ForGod'sSake]

Have you seen other articles about impacts contemporaneous with the one believed to have hit northern North America ~12,900 years ago. I've seen other posts/articles discussing black mat layers etc in other parts of the northern hemisphere and assumed it was the result of the one that hit northern NA, but nothing this far south.

I hadn’t seen anything about something that far south, either (that I recall) but having multiple parts of the same object arrive at slightly different times appears to be more common than the reverse. We should all wait to see about the dating of this new find — perhaps it happened earlier or later, like perhaps it’s dated the same as Berringer crater(still no solid, agreed-upon date for that impact).
