There's only one way that they can be formed over millions of years. An animal dies, it soon is compressed with heat/pressure and turns to sediment. The only other way is if you want to make a false fossil. Just use plaster.
Accualy, no. fossils can be formed by....
1. sediment piling on the substance and creating a mold
2. an orginism may be incased in ice, which counts as a fossil
3. mud, bogs, and mucky water may presurve an orginism
4. heat and pressure makes a metamorphic rock, and only sedimentary rock can weild fossils
HOPE I HELPED ^^ IF I DID CHECK OUT JEALOUSNOTAHATER ON YouTube, SUBSCRIBE, RATE, AND COMMENT TOO.
I kept his answer so you could see how wrong he is lol :)
oh, they can also be incased in amber, a sticky substance that ozzes out of trees to protect them from paricites
Many fossils form because an animal dies and its body sinks to the ocean floor where it is buried in sediment. The bone sinks in the sediment and more is added on top. As the pressure increases the sediment turns into rock. The bone then dissolves from water and leaves a hole in its place. This natural mold is filled with minerals from the water. The area surrounding the fossil is then brought back to the surface after millions of years of erosion.

There are several ways plants and animals can be fossilized. These include freezing and drying, asphalt, amber, carbonization, and permineralization.
There are very few ways to truly preserve a fossil. The best way to preserve a fossil is to close it up in an air-tight container.

The preserved remains of an animal is known as a fossil.
Something that is not preserved could be live, decomposed, etc.
Animals preserved in ice or snow are commonly referred to as "ice mummies" or "ice age animals." These animals are often well-preserved due to the freezing temperatures, allowing scientists to study their remains and gain insights into their past.
Most fossils are found in sedimentary rock, which is the most common type of rock on Earth. Sedimentary rocks form when particles of sediment are deposited by water or wind, and then hardened over time.

fossils
a fossil is a preserved remain or trace of an organism that lived in the past
it is mostly preserved in sedimentary rock
The preserved remains of animals of evidence of their existence are Fossils Fosssils that provide evidence about the past are called trace fossils.

fossil's that have been preserved over a long period of time
Most fossils are preserved in sedimentary rocks.
The remains are called fossils.
