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,

Clovis range predates and postdates hypothetical Younger Dryas Event

Clovis range predates and postdates hypothetical Younger Dryas Event

Clovis people: Narrow window of tool-making
Tools made by some of North America's earliest
inhabitants were made only during a 300-year period
Texas A&M University, PhysOrg, October 23, 2020
https://www.sciencedaily.com/releases/2020/10/201023123104.htm

Clovis range is ~13,050 to 12,750 cal yr B.P.
according to Figure 2 of below paper. Thus, this
interpretation has Clovis culture unaffected by
whatever happened at the Younger Dryas Boundary.
