What minerals are in dinosaur fossils?

A common mode of fossilization is mineralization, the replacement of organic material by inorganic minerals. The most common dinosaur fossils are the mineralized remains of bones and teeth. Bones are composed of calcium phosphate and organic material. Common mineralizing media are calcite, iron minerals, and silica.

What do minerals have to do with fossils?

These crystallized minerals cause the remains to harden along with the encasing sedimentary rock. In another fossilization process, called replacement, the minerals in groundwater replace the minerals that make up the bodily remains after the water completely dissolves the original hard parts of the organism.

Can minerals contain fossils?
