Are There Dinosaur Bones on the Moon?

Ah, the latest tabloid science claim; that the Chicxulub Asteroid hit the Earth so hard it threw dinosaur bones to the moon.

This is being run by all kinds of, shall we say, "interesting" news outlets including our old friend the Daily Mail, but I can't find a single reputable source. When Esquire is the "best" outlet.

The actual source of the theory appears to be a 2017 book, The End of the World, written by a science journalist named Peter Brannen using work by a guy named Mario Rebolledo. The argument is that the impact was so huge it, uh, tore a hole in the atmosphere, creating a vacuum, followed by massive winds that...expelled large chunks of the Earth.

Mario Rebolledo appears to actually be Mario Rebolledo-Vieyra, a hydrogeologist who works for the Centro de Investigación Cientifica de Yucatán. So he's from the right part of the world to have opinions on this.

And per ResearchGate, he has written a number of papers on the Chicxulub impact. In fact, he seems to be more than a little obsessed with it. Which isn't necessarily a bad thing.

He's also written an unpublished paper (in 2019) about moon rocks.

So, this could be a legitimate theory this guy has.

Is it possible?

Impact craters, regardless of size, produce ejecta, that is to say things are thrown out of the crater during the impact and deposited around it. The Chicxulub ejecta, according to one study, launched 70 billion kilograms of rock into space. Some of that rock could have had dinosaurs in or attached to it.

And some of that rock would have hit the moon, and it might have contained dinosaur bones. However, the ejection and the crash into the moon would almost certainly have pulverized them.

Meaning, for once, the tabloids could be right. There could be dinosaur bones on the moon, but we're not going to find an entire t-rex up there.

Just, potentially, material that could be powdered bone.
