Trilobites are a fossil group of extinct marine arthropods that form the class Trilobita They feature the following significant attributes:

Trilobites form one of the earliest known groups of arthropods.
The first appearance of trilobites in the fossil record are from the Early Cambrian period (521 million years ago).
They were hard-shelled, segmented creatures that lived in Earth's ancient seas.
They are considered to be one of our planet's earliest complex life-forms and are one of the essential signature creatures of the Paleozoic Era.
Trilobites went extinct before dinosaurs ever existed.
Trilobites were the first creatures with a skeleton (Exoskeleton), so they were easily fossilized.
Their shell is divided lengthwise into three lobes (hence, the name TRILOBITE meaning three-lobed): a central axial lobe, and two symmetrical pleural lobes that flank the axis.

Morphologically, the trilobite body divided into three major sections:

cephalon (or head) with eyes, mouthparts, and sensory organs such as antennae.
a middle region called the thorax with several overlapping segments(anywhere from 2 to 61)
pygidium (or tail section) in which the segments
