Trilobite Fossils
Trilobite fossils are ancient marine arthropods, whose name translates to 'three-lobed one.' These extinct organisms lived over 500 million years ago during the Cambrian period and became extinct around 250 million years ago. Trilobites have a distinct body structure characterized by three longitudinal sections: the cephalon (head shield), thorax (middle section), and pygidium (tail shield). These fossils come in various shapes, sizes, and colors and are often found with well-preserved details of their exoskeleton. Trilobites are highly sought after by collectors due to their historical significance, rarity, and intricate patterns. They are a part of the 'Collectibles' category due to their value as collectors' items, while being classified under 'Rocks and Minerals' because they are geological formations. Trilobite fossils also fall under the broader category of 'Fossilized Shark Teeth' since both are remnants of prehistoric marine life.
