Preservation of the fossil is the best in Sedimentary rocks.


Any life form that got caught up in an igneous lava flow for example would be completely burned up and never be preserved in the rock record. Some fossils in sedimentary rocks if they are deeply buried and deformed and become metamorphic rocks also tend to lose any fossils that were once there.
