The Cellar / Rocks

I intended to put this in the Science thread but discovered we don't have one.

I don't completely buy the story about the origin and transport of the pricey "Martian" rock sold at auction yesterday.

So I am curious if there are any Earth rocks on Mars.

4.3M for a rock, we collect rocks but that's too much.

There are undoubtedly Earth rocks on Mars, at least from when the Moon was formed.
