How does a cast fossil form?
When the animal dies its skeleton settles on the sea floor and is buried by sediment. that thickens and begins to turn to stone. The skeleton dissolves and a mold is formed. Minerals crystallize inside the mold and the cast is formed.
Why aren't animal remains not found in granite?
Animal remains are not typically found in granite because granite is an igneous rock formed from the slow crystallization of magma beneath the Earth's surface. This process involves extremely high temperatures and pressures, which would destroy any organic material, including animal remains. Additionally, granite forms in environments where sedimentation does not occur, making it unlikely for fossils or remains to be preserved within it. As a result, animal remains are generally found in sedimentary rocks, which are formed from the accumulation of sediment and can encapsulate fossils.
Why is scavenging an example of a eater-eaten relationship?
scavenging is an example of an eater-eaten relationship because animals who feed on the dead animals may be eaten by other live animals when they are dead....For Example; Vultures feed on dead animals but when the vulture is dead another live animal will feed on it and when that live animal becomes dead another animal will feed on its dead body and so on...
What are three ways fossils can be preserved?
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
What are animals that feed on dead organic matter called?
Fungus is the organism that feed on dead an decaying matter.Animals that feed on dead remains are called Scavengers eg Crow,Vulture.
This type of fossil is formed when an organism is buried in sediment which hardens into rock. After the soft parts of the animal rot away a cavity remains?
mold
How does a cast fossil form?

What are fossils that form when mud buries a plant or animal and then quickly hardens around it called?
Fossils that form when mud buries a plant or animal and then quickly hardens around it are called "cast fossils." This process often occurs when the original material decays, leaving a mold that is then filled with minerals or sediment, creating a replica of the original organism. The rapid hardening of the surrounding material helps preserve the details of the organism, allowing for a more accurate fossil representation.
What is an organism like an insect that Eats the remains of an animal?
waste and recycle
Which forms first a fossil mold or a fossil cast?
First, a thin layer of sediment hardens and forms a mold. Then, what is known as a cast is when a new layer of sediment fills in the mold breaking down the creature/ animal/fossil.
Are preserved animal tracks index fossils?
According to the definition of "Index Fossils" the answer is no. The definition of an "Index Fossil" is - remains of an organism that lived in a particular geological age. While the track itself may indicate the age of sediment, it is not a fossil.
What are mold and cast fossils?
A fossil mold is formed by the impression left in rock by the remains of an organism. A cast fossil occurs when the mold is filled in by precipitating minerals.
A kind of fossil were an animal or plant leaves only its body impression in the mud?
A fossil of this type is called an impression fossil. It forms when an organism's body creates an imprint in soft mud or sediment, which then hardens into rock and preserves the shape of the organism but not its actual remains. These fossils provide important information about ancient organisms and their environments.
What is loose material such as bits or rock minerals and plant and animal remains called?
The loose material is called sediment. It may include bits of rock, minerals, and organic material like plant and animal remains. This sediment can accumulate in layers over time and eventually become sedimentary rock through processes like lithification.
What are mold fossils?
a mold fossil is an impression of a living thing that is formed into a rock
How do fossil records form?
Typically something dies and gets buried in sediment. Over time the sediment transforms to sedimentary rock and the remains of the dead plant or animal fossilizes. There are a few variants on this but that is the basic process.
What is a fossil evidence of?
A fossil is evidence of a once living animal. A fossil is created when an animal dies in a mud or other soft dirt or sediment. Over time, the animal will decompose and leave the bones. Over time, these bones will get covered by dirt, rocks water, etc. After a couple thousand years the bones will get compressed into sediment, waiting to be discovered. Something similar to a fossil is and imprint. This is where an impression of a plant or animal is pushed into a soft sediment and hardens.
