Elrathia Kingi Trilobite
Trilobites are an extinct group of marine arthropods in the class Trilobita, and they rank among the earliest complex life forms on Earth. Emerging around 521 million years ago during the Early Cambrian period, these fascinating creatures were widespread in the oceans of Europe, Asia, and other ancient seas, thriving throughout the Paleozoic Era long before dinosaurs appeared.
Trilobites were the first animals to develop a hard exoskeleton, which made them highly fossilizable and preserved their intricate details for millions of years. Their distinctive body design, divided into three longitudinal lobes—a central axial lobe and two pleural lobes—gave rise to the name “trilobite,” meaning “three-lobed.”
The trilobite body consists of three main sections:
-
Cephalon (head) – with eyes, mouthparts, and antennae for sensing the environment.
-
Thorax (middle) – featuring multiple articulated segments (2 to 61) for flexibility and movement.
-
Pygidium (tail) – composed of fused segments forming the rear section.
Trilobite fossils are highly valued by both paleontologists and fossil collectors. They offer a window into Cambrian marine ecosystems, early arthropod evolution, and the incredible diversity of Paleozoic marine life.
Please be aware of the nature of fossils:
Being buried under the ground for millions of years under tons of pressure tends to be rough. No fossil comes out of the ground whole and perfect. Most fossils have undergone some restoration, while others are altered by man simply to enhance their presentation in different ways. The workers in the United States do a very professional job, unearthing and preserving these natural treasures
