How can you tell how old a shell is?
Divide the total number of ridges by 365. Because scallops produce about a ridge per day, dividing by 365 will give you the approximate age of the scallop, before it died or abandoned the shell, in years.
Are ammonite fossils rare?

As mollusks live their daily lives in the sea, they take in salts and chemicals from the water around them. As they process these materials, they secrete calcium carbonate, which hardens on the outside of their bodies and begins to form a hard outer shell.
Do seashells turn into sand?
None of the critters whose activities result in turning seashells into calcareous sand, or simply putting the calcium carbonate back into the ecosystem, are directly nourished by the seashells. Instead, they either break the shells up to get to the living animal inside or they use them for their homes.
