Elrathia Kingi Trilobite
Trilobites are an extinct group of marine arthropods that lived during the Paleozoic Era, making them some of the earliest complex animals on Earth. First appearing around 521 million years ago in the Early Cambrian period, trilobites thrived in ancient seas and became a defining feature of Cambrian marine life, long before dinosaurs appeared.
These ancient creatures were the first to develop a hard exoskeleton, which allowed their bodies to be well-preserved as fossils. Their shells were divided into three longitudinal lobes—a central axial lobe and two pleural lobes—giving rise to the name “trilobite,” meaning “three-lobed.”
Trilobites had a distinct three-part body structure:
-
Cephalon (head) – housing eyes, antennae, and mouthparts.
-
Thorax (middle) – composed of multiple movable segments for flexibility.
-
Pygidium (tail) – fused segments forming the rear portion of the body.
Today, trilobite fossils are highly valued by paleontologists and fossil collectors alike. They provide crucial insights into Cambrian ecosystems, the evolution of prehistoric arthropods, and the diversity of life during the Paleozoic Era.
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
