No, it is a rare occurrence for something to be fossilized.
The vast majority of animals do not fossilize because their bodies are either scavenged by other animals or broken down by bacteria or fungi.
Most fossils are found in water-lain sediments when the bodies have been buried quickly or fallen into an area where the water contains very little oxygen preventing most bacteria from attacking the body.

Hard parts such as bones, teeth, and shells are most likely to become fossilized as they have a higher chance of being preserved over time. Soft tissues like muscles and organs usually decay before fossilization can occur.

Most plants and animals are not immediately covered by sediments immediately at death. The soil or water conditions also play a big part. Plants rot and animals decompose, or are scavenged. The rare occurence is to be covered in a mineral rich environment quickly.
why do you think many animals and plants did not become fossils
They are under Uberpressure and heat cannot be decomposed before they are covered by rocks. Most of the time they do rot away though.
Less than 1% of all organisms that die become fossilized.
Most animals that became fossil fuels (coal, oil and natural gas) were tiny plankton in the oceans. Coal was made from larger vegetation and possibly animals like archosaurs, the reptile ancestors of the dinosaurs.

lots of different animals feed on dead animals. this could be the cause of lack of food but it is usually just easier for wild animals to eat a animal that they found dead as they do not have to hunt. most animals (including humans) eat animals that are dead as it would be hard to eat them if they were still living and moving.animals that find other animals dead and eat them are call scavengers. an example of this type of animals is the hyena.i hope this helped :)Vultures
Trilobites are animals that existed millions of years ago. Geologists, anthropologists, and paleontologists study the fossilized remains of this animal.
