Basic conditions for the formation of fossils:
(1) Organic matter must have a hard part such as shell, bone, tooth or woody tissue. However, under very favorable conditions, even very fragile organisms such as insects or jellyfish can become fossils.
(2) The creature must be immediately destroyed after death. If the body of a creature is partially crushed, rotted or severely weathered, this may change or cancel the possibility of the organism becoming fossilized.
(3) The organism must be quickly buried by a substance that can hinder decomposition. The type of buried material usually depends on the environment in which the organism lives. The remains of marine animals can usually become fossils，This is because marine animals sink to the bottom of the sea and are covered by soft mud. The slime became shale or limestone in later geological times. Finer-grained deposits do not easily damage the remains of the organism.
