Preserved fossils in sedimentary shells are of the following types:
(1) Whole shielded animal - It is very rare that fossils of any creature dissolve without any kind of dissolution, but examples of such preserved fossils are found in fossils of Mammoth and Rhinosaurus, which have been found frozen in the snow of tundra.
(2) Skeleton often found in shadow preserved in an unchanged condition - Sometimes when only the skeleton is preserved in the shells, it has been seen that it is in its former state, when it was a sad person. The only change is that the phospholate is eliminated from the skeleton of organic matter.
(3) Carbunization - In some plants and some organisms, such as graptolite, in which the skeleton is made of chitin, the original material becomes carbonated. There is an incidence in the organism, which leads to the disappearance of oxygen and nitrogen and carbon remains.
(4) Template of skeletons - Occasionally the skeleton or armor merge, and in their place, only the mold remains. It is thus that after being covered with the shell of the armor, the inner part of the armor is also filled with depression. After that, carbonic acid mixed water reaches in the rock and reaches the place where the armature remains, and completely dissolves it in the form of calcium bicarbonate. As a result, only one mold of internal and external shape of armature is found in place of armor. The place between these two was essentially the armor, and if the place is filled with wax, then the realm of the armor gets molded.
