The Trilobite was perhaps the most common inhabitant of Earth's primitive seas. Dozens of species of trilobites have been identified and they existed for more than 200 million years before becoming extinct before even the dinosaurs existed. Sometimes referred to as "mud bugs", trilobites lived on or near the soft sea floor and probably ate the remains of other sea creatures which had died. Ranging in size from under a millimeter to over 2 feet. All trilobites have a similar body configuration and are composed of three main parts: a cephalon (head), a segmented thorax, and a pygidium (tail piece). Trilobites means "three-lobes" and refers to the long central lobe flanked on either side by similar pleural lobes.
As each is a natural fossil each one is unique. There will be variations in the coloring and size from piece to piece. No two will be alike!
