You haven't told us anything about its size, weight, physical properties or where you found it. However, in this case it doesn't matter too much. Your rock doesn't have any exterior features which would suggest it might be a meteorite. It just looks like an ordinary piece of nodular rock. Perhaps a chert nodule.
i am so sorry my reply was late.
at the first,
thanks for your replying.
i do what you said,
pls,
see it and tell me if it a meteorite or not.
thanks again.
I have looked again and it still doesn't have any features to suggest it's a meteorite I'm afraid. The density is quite low... to the extent that it may have a hollow cavity in the middle. Perhaps it's a geode (but terrestrial, not meteoritic).
I don’t think it’s a meteorite as it doesn’t show any signs of being one. If it was a meteorite, the density wouldn’t be that low. Also, have you tried doing a magnet test?
