There are arguments that seismic waves from the Chicxulub impact did a superfrack job on the Deccan flood basalts and magnified their eruptions. See-

What Is This Thing? Mystery Rock or Meteorwrong?

What Is This Thing? Mystery Rock or Meteorwrong?

On Reddit, there is an item (rock?) labeled "AN/TCS-62" that many people are guessing is either a meteorite or Moon rock at:
https://www.reddit.com/r/whatisthisthing/comments/jr62jh/my_grandpa_gave_this_to_me_before_he_died_does/

Although I disagree with either identification, the members of this list might have fun making their guesses as to what this mystery specimen is.

Have fun,
