This is the best means of preservation of ancient materials. It happens only rarely. The animal must be continually frozen from the time of death until discovery. That limits the possibilities to cold hardy animals from the last ice age. There have been remarkable discoveries of mammoth and wooly rhinoceros found in ice from Alaska and Siberia. Specimens with flesh, skin, and hair intact have been found. Some of these finds suggest that they were flash frozen, with food still in the mouth and stomach.
amber tar and freezing
If they are frozen in harsh conditions, or like back in dinosaur time, animals would sink down and be preserved in tar. They could also be preserved in amber.
Fossils are preserved in three things mold ,cast ,and sediment.
hi
It is a fossil.
Well there are 3 types of fossils: Petrified Fossils, Molds and Cast, and Preserved Remains. Petrified Fossils are the organisms buried in the layers of sediment. Molds and Casts are the organisms, like shells, buried by sediments, in which they gradually dissolve. Preserved Remains are the organisms preserved in other substances. For example, entire organisms, such as huge elephant-like mammoths that lived thousands of years ago, have been preserved in ice. Therefore, Preserved Remains is a major type of fossil that does not form in sediments. This can be formed by decades of being stuck in the ice age and eventually falling through the ice and never getting out. Since you cant get out you get frozen! Being frozen and preserved in another type of substance in called... Preserved Remains! --Hope this could help. Thanks for reading.:)
Fossils, although technically they are not preserved in the earths crust; the minerals in the bones and pore spaces have been replaced by other harder minerals which take much longer to weather.There are a number of different fossilization processes. See this link :How are Fossils Formed?

The remains of an animal. -------------------------- Fossils are the remains of a dead plant or animal that have been preserved for a long time.
