Greetings kind people,
I'm so sorry if this is such a noob question. But I've searched and searched but I couldn't find answers to these on internet.
(kindly correct me because I feel I maybe wrong):
Smithsonian website said licking dinosaur fossil helps in identifying between a rock or a fossil... But isn't fossil a rock in itself? Fossils are made because minerals get replaced and it's not possible for bone to remain in its original state for millions of years. So, it's not the original material anymore.. so licking a fossil should equal to licking a rock? In that case, licking should not work?
