Their distinctive feature is a shell composed of separate armored plates, which on first glance, strongly suggest the repeated segments of an arthropod , such as a trilobite.The trilobites may have gone extinct (along with 95% of marine species) during the mass extinction at the end of the Permian period, but that doesn’t mean that they were a failure. On the contrary, the trilobites survived for more than 250 million years (longer than the dinosaurs), and dominated seafloor ecosystems for much of this time.

Ptychopariida (pronounced Pity-cho-pa-ree-da) is a huge and morphologically diverse order of trilobite that has largely defied science's attempts to unravel its phylogeny through cladistics. Many ptychopariids were among the most primitive trilobites dating to the early Cambrian.Trilobites were some of the first complex animals to appear in the fossil record and were extremely successful during their time. They existed in the oceans for more than 300 million years, and 20,000 different species have been found.

Affinities of Trilobites: The trilobites are the oldest of all arthro­pods and bear a number of primitive char­acters—1. Presence of innumerable number of thoracic and abdominal segments. 2. Ar­rangement and nature of appendages. 3. Head region together with its appendages is unspecialised.Trilobites emerged fully formed upon the Cambrian scene. By the time, some 521 million years ago, that the initial members of this ancient line of arthropods began filling oceanic environments around the globe, they were already creatures with highly developed eyes, complex digestive systems and admirably functional calcite carapaces.
