There have been organisms from the beginning of time that have had hard parts on their body. This is described in creationism.
Hard parts
The sediments that do consists of mostly microscopic shells and hard parts of organisms is Clay.

Most organisms during the Precambrian time did not have hard body parts. They were mostly soft-bodied and lacked the mineralized structures seen in later periods.
Any foreign substance that can enter an organism by diffusion can seep into an organism and replace its hard parts.
Rapidly buried by sediments
hard body parts
Fossils can form from both soft parts and hard parts of organisms. Soft parts can become fossilized through processes like carbonization or preservation in amber, while hard parts like bones or shells can undergo mineralization or replacement to become fossils.
multicellular organisms begin as a single cell.
When an organism dies, its soft parts often decay quickly or are eaten by animals
Ones with hard bony parts, soft tissues do not from fossils.
