you've read through ALL those links I suggested in another post and you're still not convinced?!?!?!? Wow. Many of them had significant lists of scientific references...follow them until you run out of information.

A good general book on how fossilized bones tell us what they do is What the Bones Tell Us Also explains why some bones weather and some remain to be turned into fossils--very interesting info.

After people give you good advice about stuff to read, it seems rather odd that you keep singing the same old "I don't believe this" song without reading the stuff first. So I assume your question/complaint is really not about wanting information, but is about something else. The information is out there and easy to find.
