Some small mammals also survived the Cretaceous–Paleogene extinction event some 66 million years ago...luckily for us!

A team of scientists claims to have found the first-ever definitive evidence of a comet striking Earth.
After conducting a series of analyses, the researchers determined that a mysterious black pebble discovered years ago in the Egyptian desert is a piece of a comet nucleus — the first ever discovered.
"It’s a typical scientific euphoria when you eliminate all other options and come to the realization of what it must be," study lead author Jan Kramers, of the University of Johannesburg in South Africa, said in a statement. [Best Close Encounters of the Comet Kind]
The pebble, which the team has named "Hypatia" in honor of the ancient female mathematician, astronomer and philosopher Hypatia of Alexandria, is also studded with diamonds, which makes sense considering its cometary origin, researchers said.

!! The proverbial needle in the haystack. What are the odds.
:’)
What about that big hole in Arizona?
:’)
Where did they get the comet core sample with which to compare it? It's an educated guess at best. Maybe right, maybe wrong.
My bad. Considering I have one of these in the kitchen cabinet, you would think I would not have made that kind of goof.

No to the Gulf of Mexico. The 65myo boloid that killed the dinosaurs was partly in Yucatan and somewhat more in the Gulf of Mexico, but with a diameter of 120 miles was not big enough to shape the whole Gulf. The 200mya plus one that killed most species has not yet been definitively located. On the other hand, anyone know about Hudson’s Bay??
Yeah, it definitely looks like one, but it wouldn’t be from the K-T impact. When the Alvarezes were trying to find the impact site, someone wrote in to one of the sci mags suggesting Iceland — that the impact punched a hole through the crust and produced the volcanic phenom we now know and love there. :’)
And roaches.
