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.

The 54 lb. Martian rock that sold in New York is worth only a few thousand dollars; but, the import tariff on things coming from Mars is astronomical lately!

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

The Chicxulub impactor, which created the Chicxulub crater in the Yucatán Peninsula in Mexico killing off the dinosaurs 65 million years ago, may have blasted some dinosaurs into space and their bones may have landed on Mars. Unfortunately, after millions of years on Mars, they’ve been pulverized by meteorites impacting the red planet so we’ll probably never know.
