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.

∙ 13y agothe fossil record is incomplete because not enough fossils get buried fast enough to be in the fossil record.. so 9 out of 10 of those fossils were not buried fast enough to become a part of the fossil record. and soft bodied organisms decay to fast in order to be buried

∙ 13y agoThey did not die and become buried in the rock that contains calcium, as the dinosaurs did. They were buried, but usually decomposed, in the dirt or other materials that did not contain calcium. Calcium is what makes fossils different than rock. The bones absorb it, and the calcium prevents total petrification.

∙ 11y agoThe soft parts of an organism hardly ever become fossilized. Usually only the hard parts are fossilized, hence we know very little about the internal organs of most prehistoric organisms. It's hypothesized that the organisms of Precambrian time had not yet developed any hard parts which is why the only fossils available from those very early times are trace fossils.

∙ 13y agoIt is because the soft part of organisms have rotted away.

∙ 13y agono, the squishy bits get eaten by other animals or decomposed by bacteria and such. it's the bones, exoskeleton, nails, teeth, and claws that stay.

What type of organism is the most fossil evidence available?
Organisms with hard parts such as a mineralized shell, like a trilobite or ammonite, are much more likely to become fossilized than animals with only soft parts.
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.
Fossils can only form when?
Fossils can only form when the conditions are right. These conditions are in a sedimentary layer of the earth which are able to preserve soft and hard parts of the item.
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 is the Difference between Precambrian rocks and Paleozoic rocks?
Paleozoic rocks contain fossils while Precambarian rocks had no fossils since at that time there was only single celled organisms.
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 are asphalt fossils?
Tar is known as Asphalt fossils. Asphalt preserve only hard parts of organisms such as teeth, bones and the outer shells of spiecies. Countless numbers of these fossils are preserved in tar pits.
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 animals don't become fossils?
Any internal organs. Only bones become fossils.
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.
What type of organism is the most fossil evidence available?
Organisms with hard parts such as a mineralized shell, like a trilobite or ammonite, are much more likely to become fossilized than animals with only soft parts.
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

Fossils can only form when the conditions are right. These conditions are in a sedimentary layer of the earth which are able to preserve soft and hard parts of the item.
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.
