Trilobites are an extinct group of marine arthropods that thrived during the Paleozoic era, approximately 521 to 252 million years ago. Characterized by their segmented bodies and distinct three-lobed structure, these ancient creatures inhabited diverse environments, from shallow seas to deeper oceanic floors. Trilobites are often found as fossils, providing valuable insights into early marine ecosystems and the evolutionary history of life on Earth. Their various forms and sizes reflect a wide range of adaptations, making them a favorite among paleontologists and fossil collectors alike. Each specimen tells a story of the distant past, capturing the unique diversity that once roamed the oceans.
