Voids left behind by once present fossils are called 'trace fossils'.
it depends on how and were they died for example plants turn into peat, then coal animals turn into fossils if they died in the mud or sand animals or plants that are frozen would keep their hair and organs and shape both plants and animals, if nothing happened and they were left out to the elements, would just disintegrate and rot in time
Indeed: a Trace Fossil is that of a burrow, footprint, coprolite, etc that's not a fossil of the animal itself that left the trace.

fossils?
The 6 types of fossils are called body fossils, trace fossils, molecular fossils, ressin fossils, microfossils, pseudofossils, and living fossils, and i dont have the information to describe them.
fossils were formed when the animal dies it body decade's and then the only things left are the bones which over the years gets covered with mud , sand , dirt , or tar and eventually hardens and then becomes a fossil.
Molds and casts may be produced when sediments fill molds left by decayed organisms.
Mold fossils- an empty space is left when an organism is buried in sedimentary and it decays.Cast fossils- Minerals in rocks fill space left by a decayed organism.(replica)Trace fossils- Markings left by an animal. (footprints, trail, or burrow)Petrified fossils- Minerals penetrate and replace all or part of an organism.Imprint fossils
molds and casts, trace fossils, petrified wood, and carbon filmThe four types of fossils are mold fossils, cast fossils, true-form fossils, and trace fossils. Mold fossils are impressions from when the plant or animal first decomposed. Cast fossils are plant or animal remains. True-form fossils are remaining body parts from an animal. Trace fossils are marks that have been left by animal, such as footprints.
