Sometimes they do! But this is very rare!
When an animal dies, other animals will quickly eat any soft tissues exposed. If this does not happen, bacteria will rapidly decompose the soft tissues.
To get the soft tissue preserved needs very specific conditions which are quite complex. It would be worth reading about Mazon Creek and Burgess Shale, these are places where fossils with soft tissues preserved can be found.
What else can I help you with?
Why don't all organisms become fossils?
Really, anything can be fosslized. It really all depends on where it died. if it died in a lake and the lake dried and a layed of ground eroded over it than it would become fossleized by the nutrients found in that layer of ground. Like I said, depens on where it died, all that the location needs to be is a place where nutrient rich soil can preserve the bones. It just may seem like only certain organisms can be fosslized because they are all found those areas with preserving soil.
Why not all creatures from fossils?
Not all creatures are found as fossils due to a variety of factors, including the conditions required for fossilization, which are rare. Most organisms decompose quickly after death, and only those that are buried rapidly in sediment or have hard parts like bones or shells are more likely to become fossilized. Additionally, geological processes can erode or destroy fossils over time, and some environments are less conducive to fossil formation than others. As a result, the fossil record is incomplete and biased toward certain types of organisms and environments.
What is the relative age of fossils found at the top layer of rock?
They are called index fossils, fossils of organisms that were widespread, evolving quickly, and only appeared in the geologic column for a specific length of time.
What are the most common animal remains that become fossilized?
Fossils are the preserved remains or traces of organisms that lived in the geologic past. Trace fossils are made by marks left by organisms while still alive, such as tracks, burrows, and dung.Decomposition, weathering, and scavenging all contribute to what makes fossils so rare.Almost all fossils are found in sedimentary rock; almost none are found in metamorphic or igneous rock.Fossils are our only direct key to the past, informing us about migratory patterns, weather and environmental conditions, species' interaction, and animal behavior.Scientists use index fossils to place events on the geologic time scale. The organisms that become index fossils are chosen because they had relatively short geologic life spans, wide geographic ranges, and are easily identified.
Why are sedimentary rocks the only rocks with fossils?
Fossils are the hard remnant material of living organisms and hard evidence can be found from the fossils of early phanerozoic. During the early stages of formation of the earth it is supposed to consist of Igneous rocks only. Refer to the major processes of fossilization and it is found that fossils are usually related to areas nearby streams and basins (organisms require water for survival) and hence the only form of rocks can be sedimentary. In the case of metamorphic rock the remnants cannot sustain temp. and pressure changes and deform leaving no traces.
Do most dead organsims become fossils?
No, only a small number of organisms became fossils. Most dead organisms simply rot away or are eaten.
Why do only the hard parts of organisms generally leaved fossils?
When an organism dies, its soft parts often decay quickly or are eaten by animals
What animals don't become fossils?
Any internal organs. Only bones become fossils.
The fossils of organisms that were widely distributed but only lived during a short period of time are called?
They are called index fossils.
What are asphalt fossils?
Asphalt fossils are prehistoric organisms that have been preserved in asphalt or tar deposits. These fossils can provide valuable information about ancient ecosystems and species. The natural properties of asphalt can create unique conditions for preservation, including exceptional detail of soft tissues.
Can only animals with hard body parts create fossils?
When something be on side of the road like a dinousar and the fossils.

Are organs organisms?
No , because organs are only body parts of organisms.

Why aren't most of the found fossils complete organisms?
because fossils are rare to find and in complete form even more rare only 10% or less out of 100% fossils have been found on earth
What is the relative age of fossils found at the top layer of rock?
They are called index fossils, fossils of organisms that were widespread, evolving quickly, and only appeared in the geologic column for a specific length of time.
What are index fossils useful for?
Because organisms that became index fossils lived only during specific intervals of geologic time, geologists can estimate the ages of rock layers based on the particular index fossils they contain.
