Which of the major types of fossils does not form in sediments? Describe how this type can form

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!
