Well before darwin and lyell, men interested in natural science speculated about the interpretation and meaning of fossils. Remember that cuvier was the first to convincingly interpret fossils as remnants of living organisms. A fossil can take many forms: fossilized leaves may still have original tissue remnants. A dinosaur bone like this one has been mineralized: the original tissue replaced by minerals. Often the original tissue completely dissolves or decays, leaving an empty space surrounded by mud that mineralizes.
