Invertebrate fossils form a substantial part of the fossil record and are key indicators in the fields of paleontology, biostratigraphy, and evolutionary biology. These organisms, lacking vertebral columns, often had hard shells or exoskeletons which fossilized well. Their abundance and

Fossils are preserved remains, impressions, or traces of organisms from the remote past, usually embedded in sedimentary rocks. Fossilization is a rare process that involves chemical and physical changes over millions of years. Different types of fossilization processes result in

The Earth’s biodiversity is not uniformly distributed. Instead, it varies geographically due to climatic, evolutionary, geological, and ecological factors. To study and understand these variations, the world is divided into distinct zoogeographical regions, each with its unique fauna (animal life).

The International Code of Zoological Nomenclature (ICZN) provides a universal set of rules and recommendations for naming animals. It ensures that every animal species has one correct and universally accepted scientific name. The ICZN promotes stability, clarity, and universality in
