Trilobites are members of the phylum Arthropoda (jointed-foot animals). Arthropods have segmented bodies and appendages covered by an exoskeleton which provides support and protection for muscles and organs. Living Arthropods include insects, spiders, scorpions, ticks, crabs, lobsters, barnacles, and centipedes.

Trilobites belong to an extinct class of marine organisms called Trilobita. This name refers to the three-part (tri-lobes) latitudinal and longitudinal shape of a trilobite's exoskeleton. The latitudinal lobes consist of the cephalon (head), segmented thorax (body), and pygidium (tail); the longitudinal lobes consist of two lateral lobes (on each side of the body) and an axial lobe (central back area of the exoskeleton)
More than 500 different trilobite species have been found across Utah, in a broken band of Cambrian Period (570 to 500 million years old) limestones, siltstones, and shales that trends northeast-southwest across the western part of the state.

Most trilobite species were bottom dwellers that crawled over sand and mud. Some of them could curl up like modern pill bugs. Other trilobites burrowed into bottom sand and mud using their shovel-shaped cephalons.... I just think they are so ugly, that they are cute!!!!! LOL!!!
