During the Early Cambrian (about 570 to 540 million years ago), western Utah was covered by a shallow sea. Trilobite - Trilobites (phylum Arthropoda) are extinct marine invertebrate animals related to crabs, spiders, and insects. Trilobites are found among the oldest well-preserved fossils in the Lower Cambrian period. Cincinnati area rocks are filled with trilobite fragments, but only the hard outer skeletons are commonly found.

In order to grow, trilobites had to shed their exoskeletons periodically. Trilobites belong to the Kingdom: Animalia, Phylum: Arthropoda (“Arthropoda” means “joint-footed” and includes Crustaceans, Insects, Centipedes, Millipedes, Spiders, Scorpions, Trilobites, etc.), and Class: Trilobita (“Trilobite” means “three-lobed”).... trilobite. 1, Cefalon; 2, tórax; 3, pigidio; 4, antena; S, línea de sutura ... phylum Arthropoda, with a total of 448 families, 1964 genera, and 1935 species ...7.8 Phylum Arthropoda. Arthropods are an extremely diverse and abundant phylum of animals. They include organisms such as spiders, scorpions, crabs, barnacles, and insects. Unfortunately, most of these are not abundant in the fossil record because of poor preservation, but one class of arthropods does stand out in the fossil record, the trilobite.

Isotelus is a trilobite that existed between 430 and 480 million years ago. At this point in time, an ocean covered much of what is now Ohio. Isotelus is evidence of this, as it was a marine organism. A trilobite was an invertebrate creature that had a hard outer shell or skeleton.

Trilobites are a group of extinct marine arthropods that first appeared around 521 million years ago, shortly after the beginning of the Cambrian period, living through the majority of the Palaeozoic Era, for nearly 300 million years. They died out at the end of the Permian, 251 million years ago, killed by the end Permian mass extinction event ...There are fully 90 spines preserved here, making this a wonderful example of an evolutionary salvo in the predator/prey arms race. Illaenus tauricornis. Middle Ordovician. Russia Trilobite. The species epithet means "bull-horned", a quite appropriate term considering the long, sharp genal spines. Trilobites are an extinct group of arthropods, distinguished by the following characters: a body built from a cephalon, thorax, and pygidium a body divided into three lobes, running from head to tail one pair of antennae The last trilobites went extinct about 245 million years ago, but they are well represented by the fossil record.

In addition, the phylum Arthropoda contains the extinct subphylum Trilobitomorpha. This group is made up of the trilobites, the dominant arthropods in the early Paleozoic seas (541.0 million to 251.9 million years ago). Trilobites became extinct during the Permian Period (298.9 million to 251.9 million years ago) at the end of the Paleozoic Era. This is in stark contrast to the multiple jointed walking legs of a Trilobite. 3. Isopods. These hard-shelled, segmented, multi-legged creatures are a pretty convincing trilobite imposter.
