How Does a Bone Become a Fossil?

“I’ve writ­ten sev­er­al books about dinosaurs and fos­sils. So when an edi­tor asked me to take a close look the fos­siliza­tion process, I was real­ly excit­ed. I learned all kinds of inter­est­ing things while research­ing the book. For instance, sci­en­tists have found every­thing for spi­ders and flower petals to bird feath­ers and gas bub­bles made by ter­mites encased in amber.”
