Yes, shell-shaped minerals can be found in rock cavities known as geodes. These geodes can form in sedimentary or volcanic rocks and can contain minerals such as quartz, calcite, or amethyst that have crystallized within the cavity. While not actual fossils, geodes are a type of mineral formation often found in rock cavities.
Calcium is the most important mineral found in egg shells. It is essential for the formation and strength of the egg shell, providing structure and protection for the developing embryo inside.

The shell-like folds in the nasal cavity are called nasal conchae or turbinates. They help to increase the surface area of the nasal cavity, which aids in warming, humidifying, and filtering the air that we breathe in before it reaches the lungs.
A ring-shaped shell of gas around a star is called a circumstellar disk. These disks are often made up of dust and gas and can be found around young stars where planets are still forming.

A geode starts out as basically a cavity or pocket in otherwise solid rock. The cavity walls grow inward as mineral crystals grow from solutions that seep into it. In time, the cavity may become completely infilled with mineral crystal. The geodes that are found on the surface are survivors of weathering which eroded the rock in which they were once emplaced. This is because the geodes are composed of minerals such as quartz which are more resistant to erosion than the rocks which originally surrounded them.

the cochlea are located in the ear. It is a spiral-shaped cavity of the inner ear that resembles a snail shell and contains nerve endings essential for hearing.
The tendency of a mineral to break and produce smooth, curving shell-shaped surfaces is called conchoidal fracture. This type of fracture results in glassy, curved surfaces similar to the inside of a seashell. It is commonly observed in minerals like obsidian and quartz.
no because a mineral must be inorganic. a shell is organic.
