| Why this rock is probably not a meteorite:
...because if it looks like a vegetable, it's not a meteorite.
|What is it?
Hard to say, but I bet it consists mainly of quartz.
Note added later: One informed viewer called this a fossil
coral. We've received samples of coral in the past that people have
mistaken for meteorites. Another person said that it was a quartz
geode. I suspcet that's correct.
