When an organism is buried it is usually in sedementary rock, which is sof and layered. Over time the layers of sedements compact and can soak into the bones of an organism. As the bones are put under extreme pressure the become more like rocks and are thus presserved.

∙ 11y agoOver time if the bones are covered by silt, dirt they can often preserve the bone. Time, pressure and the right environmental conditions are all factors in arriving at fossil which are not often the actual bones of the animals much as they are imprint within the dirt or rock where the bones were left or a cast in other words.

∙ 8y ago- it must be buried very quickly to prevent decay and/or scavenging
- it must remain buried long enough for the sediments it was buried in to turn to rock
- minerals must substitute for the organic material
- tectonic forces and erosion must return the newly formed fossil to the surface

What is an unaltered fossil?
It's when the rock dies and is attacked by decomposers. This is why it has a small chance of becoming a fossil, but if it does, it gets covered by sediment where it slowly starts to decay. The rock then starts to be preserved where the first layer of sediment is compressed by the weight.
Do all organisms become fossils?
No. The hard bones are more likely to form a fossil. The soft parts will degenerate over time. This is why most of the fossils from the Pre-Cambrian and Cambrian periods are mostly shells, not the actual animals that inhabited them.
Describe the process by which most fossils form?
1. An ancient animal dies and sinks to the bottom of a river 2. Layers of sediments cover the animal's body 3.Over millions of years, the sediment harden to become rock. The animal is preserved as a fossil. 4. The rock erodes. The fossil is exposed on the surface of a rock.
What are cast fossils?
One form of fossil forms when an organism dies and its body is covered by layers of sediment. As time passes, the organism itself, particularly when composed primarily of softer materials, is eroded and carried away, leaving a negative imprint of its body. This type of fossil is called a mold. A cast fossil forms when a mold fossil is filled with some form of mineral, usually through the seepage of water depositing the minerals within the mold. In time, the mold is filled and the materials deposited harden, creating a replica of the original fossil. This is called a cast fossil.
How would a fossil form through mineral replacement?
Fossils form through the process of mineral replacement beginning when an organism dies and is buried. Groundwater seeps around the organism, and the minerals in the water gradually replace the minerals in the hard parts of the organism. Over time these minerals turn into a stone replica of an organism.
When does a fossil become a fossil?
when an animal dies and there are things on top of it.it stays there for a century and then it turns in to a fossil.
How might carbon atoms in the air eventually become fossil fuels?
Carbon atoms are absorbed by vegetation through photosynthesis. If this vegetation dies and is covered so it does not release its carbon, then over millions of years the pressure and the heat acting on it might turn it into fossil fuel. If humans are still living then they will surely have no need to dig it up and release the carbon.
What happens to Lionblaze?
He might become deputy once Firestar dies
Can a snail become a fossil?
Yes, snails can become fossils. When a snail dies, its shell may become buried in sediment and over time, minerals in the sediment can replace the original material of the shell, preserving it as a fossil. Fossilized snail shells can be found in many different types of rock formations.
How does e leaf becomes fossil?
when it dies

What might happen to a plant if all the eggs laid by an adult butterfly survive to become larvae?
The adult butterfly dies and eggs become a larvae.
How does something become a fossil?
when a living organism dies on the surface of the earth and sediment pile on it over time and it decays.
How long does young men become monks in Thailand?
They might become monks for 3 days or a week when a parent dies, or they might remain monks for years. It is traditional for Thai men to become a monk at some time in their lives.
What type of fossil could be formed when a plant or an insect dies?
skeletonized
When an organism dies decays and leaves its shape in rock then rock is filled in with minerals that harden?
It's either Fossil or a Trace Fossil.
When a species dies out what does it become?
When the last living member of that species dies, the species become "extinct".
