What soft parts of organisms are most likely to become fossils?
Soft tissues such as skin, fur, feathers, and organs are less likely to become fossils compared to hard parts like bones, teeth, shells, and exoskeletons. Rapid burial in sediment or other materials can better preserve soft parts, but this is less common than the preservation of hard parts.
What organisms form into a fossil?
Organisms that have hard parts such as bones, shells, or teeth are more likely to form fossils. Soft-bodied organisms can also be preserved in certain conditions, such as being quickly buried in sediment or trapped in amber.
What generally happens to the remains of a plant or animal when it dies How does this help explain which parts of plants or animals usually form fossils?
When a plant or animal dies, its remains decompose, but sometimes they can become preserved in sedimentary rock or hardened resin, forming fossils. Hard parts like bones, shells, and teeth have a better chance of becoming fossilized compared to soft tissues, which decay more quickly. This is why fossils of hard parts are more commonly found in the fossil record.
What kind of animal part leaves the most distinct fossil?
Animal parts that are soft and don't have a skeleton leave the worst imprints. Fossils are made with animal parts that are hard and durable.
Fossils can only form when?
Fossils can only form when the remains of a plant or animal are buried in sediment quickly after death. The organic tissues are gradually replaced by minerals from the surrounding environment, creating a fossilized replica of the original organism. The process of fossilization usually requires specific conditions such as lack of oxygen, minimal disturbance, and the presence of water and minerals.
