Elrathia Kingi Trilobite

Trilobites were an extinct group of marine arthropods in the class Trilobita and are among the earliest complex animals to appear on Earth. They first emerged around 521 million years ago during the Early Cambrian period, marking the start of the Atdabanian stage, and thrived in the oceans throughout the Paleozoic Era, long before dinosaurs existed. These creatures had segmented bodies covered by a hard exoskeleton, divided into three longitudinal lobes—a central axial lobe and two side pleural lobes—which gives them their name, trilobite, meaning “three-lobed.”

The trilobite body consisted of three primary regions: the cephalon (head), which housed compound eyes, mouthparts, and sensory antennae; the thorax (middle section), made up of 2 to 61 articulated segments providing flexibility and mobility; and the pygidium (tail), a fused section forming a protective rear shield. Trilobites inhabited a variety of ancient marine environments, from shallow coastal areas to deeper sea floors, and their well-preserved fossils are invaluable for understanding early arthropod evolution, Cambrian biodiversity, and Paleozoic ecosystems.

Please be aware of the nature of fossils:

Being buried underground for millions of years under immense pressure can be tough. Usually, fossils do not emerge in perfect condition; many require restoration, and some are even altered by people to improve their appearance. In the United States, workers perform this work very professionally, carefully unearthing and preserving these natural treasures.
