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

Look at a map of North America. Look at the Gulf of Mexico. That sure looks like a giant ancient meteor carter that the ocean filled up. At least it does to me. Because the Gulf of Mexico is round like a meteor crater. One big enough to pop off all life on Earth millions of years ago. Except for the ants, of course.
Not only that, but that has happened at least six times.
I think a meteorite differs from a comet due to composition.

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.
