The whole point of fossils is that they did not decompose and were preverved.
No. Fossils are chemicals like stone that have replaced organisms after they die.
Fossils are the remains of plants and animals that have been turned to stone.

Most fossils form in sedimentary rock, which is created by the deposition and accumulation of sediments over time. The most common types of sedimentary rock that preserve fossils are shale, sandstone, and limestone.
This process is known as biostratigraphy / biostratigraphic correlation.
Oxygen can accelerate the decomposition of organic material in fossil remains through oxidation. This can lead to the degradation and loss of important information preserved in the fossils. Additionally, exposure to oxygen can lead to the formation of minerals that can alter the original composition of the fossils.
Fossils preserved in ice or snow are well-preserved due to the cold temperatures that slow down decay processes. The frozen environment can prevent decomposition and protect the fossils from scavengers and other forms of damage, providing valuable insights into ancient ecosystems and species. Scientists can analyze these fossils to learn about the environment, climate, and biodiversity of that time period.
Fossils are typically not found in rainforests, rivers, and coastal areas due to the rapid decay and decomposition of organic material in these environments. High moisture and temperatures in rainforests promote decomposition, while river currents and coastal erosion can easily wash away potential fossil remains. Additionally, sedimentation is often insufficient in these areas to bury remains quickly, which is essential for fossilization. As a result, fossils are more commonly found in stable, arid environments where sediment can accumulate over time.
Fossils form when an organism is buried quickly after death in sedimentary rock, allowing the hard parts of the organism to be preserved over time from being compressed and mineralized. The burial process must protect the remains from decomposition and physical damage.
There are many different methods of dating fossils including their geological stratum and carbon dating. Phylogenetic trees are dated by their geological stratum because they have something called the COI gene that shows they have roots from a long time ago.
Cold and rigid temperatures or humidity as well as extreme pressure helps preserve organisms as fossils.
