ट्राइलोबाइट

Also known as trilobites

Trilobites (; meaning "three-lobed entities") are extinct marine arthropods that form the class Trilobita. One of the earliest groups of arthropods to appear in the fossil record, trilobites were among the most successful of all early animals, existing in oceans for almost 270million years, with over 22,000 species having been described. Because trilobites had wide diversity and an easily fossilized mineralised exoskeleton made of calcite, they left an extensive fossil record. The study of their fossils has facilitated important contributions to biostratigraphy, paleontology, evolutionary biol

AI overview

Trilobites are extinct marine arthropods that lived in Earth's oceans for nearly 270 million years and are among the earliest and most successful arthropod groups in the fossil record, with over 22,000 species identified. They matter scientifically because their hard, calcite exoskeletons fossilized well and left an extensive fossil record that has made them invaluable for studying biostratigraphy, paleontology, and evolutionary biology.
