Biomineralized skeletons are widespread in animals, and their origins can be traced to the
latest Ediacaran or early Cambrian fossil record, in virtually all animal groups. The origin of …

Molluscs comprise the second largest phylum of animals (after arthropods), occurring in
virtually all habitats. Some are commercially important, a few are pests and some carry …

The shells of freshwater snails are discarded as waste, which qualify as biological materials
with prospective multiple uses. To substantiate this proposition, an attempt was made to …

Ooid size in natural systems can be predicted based on the expected equilibrium between
precipitation and abrasion rates. Therefore, ooid size distributions may enable quantitative …
