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.

Trilobite Morphology. Morphologically speaking, all trilobites were variations on a surprisingly similar theme.
