The decomposition of a shell can vary significantly depending on environmental conditions, such as temperature, moisture, and the presence of microorganisms. Generally, it can take anywhere from several months to several years for a shell to break down completely. In marine environments, shells may decompose more slowly due to lower temperatures and less microbial activity. Ultimately, the specific time frame can be influenced by factors like the shell's composition and size.
