inorganic minerals replace the bones and shells in fossils.
However, some recent demineralization experiments have indicated that some original connective tissue may remain, even in very old fossils.

Calcite is a common carbonate mineral that often replaces the original mineral in fossils during the fossilization process. Calcite can help preserve the structure of the fossil while replacing the original material.
Absolutely yes, fossils of some shell creatures, like snails can be found in dry valley floors.
The difference between The differeence between the Cambrian and Pre-Cambrian is that the Cambrian fossils are ones of hard shell creatures because of thee evolved predators. The difference between Cambrian and Pre-Cambrian is that the Cambrian fossils are ones of hard shell creatures because of the evolved predators.rian fossils Cambrian and Pre-Cambrian is that the Cambrian fossils are ones of hard shell creatures because of the evolved predators.
Fossils formed when silica is added are called silicified fossils. Silica replaces the original organic material of the organism, resulting in a preserved fossil with a glassy appearance. This process can produce detailed and well-preserved fossils.

You can find the Helix, Shell and Old Amber fossils. However you can only gain two in the game. Helix or Shell as the trainer you fight in Mt Moon that found them will only allow you to take one. The Old Amber can be found at the back entrance to Pewter Museum (you will need Cut)
Limestone. However most large masses of limestone formed from coral reefs, not shells. The shell fossils in this limestone are "incidentals" due to shell dwelling organisms living on the periphery of the reef, not the bulk of the limestone.

The sarcodine with a shell made of calcium carbonate is Foraminifera. These single-celled organisms secrete intricate shells that are commonly found as fossils in marine sediment.
The 5 types of fossils are ...Imprint Fossils- an organism leaving an imprint on sediment that later hardens into rock.Mineralization Fossils- when minerals replace wood or bone to create a piece of petrified wood or a mineralization bone fossilsFrozen Fossils- when something like an animal gets taped in ice and remains their frozenCast Fossils- when it fills up a hollow moldfossils in amber- when an insect gets stuck in amber
