Trilobites and cephalopods are examples of these multi-celled animals. During the Devonian Period (380 million years ago) southern Minnesota was once again covered by a sea, leaving fossils of fish and corals scattered throughout the area.ossils are the remains of plants and animals found in rock. A fossil can be many things: a bone from a dinosaur, the tooth of a shark, a sea shell or a footprint.
Trilobites had many life styles; some moved over the sea-bed as predators, scavengers or filter feeders and some swam, feeding on plankton. Most life styles expected of modern marine arthropods are seen in trilobites, with the possible exception of parasitism (where there are still scientific debates).rilobite fossils are found worldwide, with many thousands of known species. Because they appeared quickly in geological time, and moulted like other arthropods, trilobites serve as excellent index fossils, enabling geologists to date the age of the rocks in which they are found.
