Yes it is.
The key difference between the shell on the left and the cast fossil on the right lies in their formation. The shell is a physical structure that was once part of a living organism, while the cast fossil represents a replica of the original shell's shape created by sediment filling in the mold left behind after the shell decayed or was removed. Essentially, the shell is the original material, whereas the cast fossil is a mineralized impression.
cuse they have a strong shell
A hard shell organism have more of a chance to become a fossil .
Valves means "shells." Bivalves ( two valves ) are clams. Gastropods (snails) have one shell.
cover fossil (or japanese translation shell fossil) then tirtouga (level 37) carracosta.
When an ancient animal for example Tortoise or snail die in its shell....years later another tortoise or snail can fit itself in the fossil shell.
No, a thin cavity in a rock showing where a shell has decayed is not considered a fossil. Fossils are the preserved remains or traces of ancient organisms, such as bones, shells, or imprints, that have been naturally preserved in rock or sediment over time. The empty space left behind by a decayed shell would be considered a mold or cast, not a fossil.
A "bivalve" is a mollusk that has a hinged shell divided into two halves or "valves," such as clams, oysters, and mussels.
Fossilize The dinosaur was fossilized The snail shell will be fossilized if it is not disturbed.
Kabuto is the Dome Fossil, and Omanyte is the Helix Fossil. An easy way to remember is that a helix is a spiral, and hermit crabs, such as Omanyte, have a spiral shell.
The tooth-like projections at the inner dorsal edge of the valves, often referred to as denticles or hinge teeth, serve to interlock the two valves of a bivalve shell. This interlocking mechanism helps to maintain shell alignment and stability when the shell is closed, providing structural support and aiding in the protection of the soft body inside. Additionally, these projections can assist in the prevention of predation by making it more difficult for potential predators to pry the shell open.
