Were some moon rocks really petrified wood?

Yes, some moon rocks that were initially thought to be genuine lunar samples turned out to be petrified wood. This confusion arose when a few samples were misidentified or improperly authenticated. The most notable instance occurred with a moon rock presented to the Netherlands in 1976, which was later discovered to be a piece of wood. Such cases highlight the importance of careful scientific verification in the study of extraterrestrial materials.
