The ancient ocean animal you're referring to is likely the trilobite. Trilobites were marine arthropods that lived during the Paleozoic era and are known for their distinctive three-part body structure, consisting of the cephalon (head), thorax, and pygidium (tail). They also possessed compound eyes made of calcite, allowing them to have a wide field of vision underwater. These fascinating creatures are among the earliest known complex life forms and are often used as index fossils in geological studies.
