They do, it does take some time though, and to "rot" there has to be enough humidity and airborne microbes.
If the plants and animals got covered relatively quickly by mud from a flooding river or ashes from a volcano then they would not have had time to rot.

∙ 12y agoThey did rot, just not all the way. the shells or hard exoskeletons were left over This was done through anaerobic decomposition (or with no oxygen). The shells and exoskeletons mixed with mud and were buried under sediment. then about 7km down in the earths lithosphere the were subjected to just the right temperature and pressure, and voila! coal was formed!

Most did. We're digging up those that got trapped in anaerobic environments (like underwater).
Wiki User
∙ 13y agoOrganic matter rots and non-organic matter does not. Fossils do not rot because they are not organic matter, they are an imprint of something that lived.
