Detailed explanation-1: -A common example of such fossilization is a woolly mammoth frozen in a permafrost region of Siberia and Alaska. They probably died during the late Ice Age.
Detailed explanation-2: -Fossils with this type of preservation-as the name implies-have been found frozen in ancient permafrost in Siberia. Unlike all other types of preservation, frozen remains allow direct study of the actual soft tissues and sometimes organs that made up an animal’s body.
Detailed explanation-3: -Fossils are the preserved remains of plants and animals whose bodies were buried in sediments, such as sand and mud, under ancient seas, lakes and rivers. Fossils also include any preserved trace of life that is typically more than 10 000 years old.
Detailed explanation-4: -Animals trapped in ice or frozen soil are protected from predators that would normally consume them. The freezing temperatures also slow the process of bacterial decay. Frozen specimens can also have intact skin, hair and even organs! Tar is also a good natural preserver of animal and plant remains.
