What is Trilobite?
Trilobites are extinct marine arthropods that lived over 520 million years ago. They are characterized by their three-lobed body plan, which gives them their name. Trilobites are among the most diverse groups of extinct animals, with over 20,000 species described. They are found worldwide, and their fossils are often well-preserved, making them popular among collectors.
