Fossilized crinoids - Fossils are primarily found in sedimentary rocks because these rocks form at low temperatures and pressures. Igneous rocks form at temperatures and pressures that are high enough to destroy any organic remains.

 
The majority of fossilized crinoids are none so lucky as to be perfectly preserved in delicate detail.
