Things that usually were not made of bone were not preserved. Although there are some like leaves and feathers that were. Also some that were found in amber are those that would not be preserved otherwise.
Petrified fossils: where organic material is replaced by minerals. Mold fossils: where the shape of an organism is preserved in sediment. Cast fossils: formed when a mold fills with minerals, creating a replica of the organism. Trace fossils: records of biological activity, like footprints or burrows. Amber fossils: organisms preserved in hardened tree resin.

Preserved remains of a living thing are called fossils. Fossils can be bones, shells, imprints, or traces of ancient organisms that have been preserved in rocks. They provide valuable information about past life forms and environments.
The fossil that is not preserved and starts with a D is a "dinosaur." Fossils are the preserved remains or traces of ancient organisms, but dinosaurs themselves are not preserved as fossils. Dinosaurs were a diverse group of reptiles that lived millions of years ago, and their fossils provide valuable insights into the Earth's history and the evolution of life on our planet.
