Elrathia Kingi Trilobite
Trilobites are an extinct group of marine arthropods from the class Trilobita, and they rank among the earliest complex animals in Earth’s history. First appearing around 521 million years ago during the Early Cambrian period, trilobites thrived in ancient oceans and became iconic members of the Paleozoic Era megafauna, long before the rise of dinosaurs.
These fascinating creatures were the first animals to develop a hard exoskeleton, which made their remains easily fossilizable. Their bodies are divided into three longitudinal lobes—a central axial lobe flanked by two pleural lobes—giving them the name “trilobite,” meaning “three-lobed.”
Trilobite anatomy is organized into three main sections:
-
Cephalon (head) – with eyes, mouthparts, and sensory organs like antennae.
-
Thorax (middle) – made of multiple overlapping segments (ranging from 2 to 61) for mobility.
-
Pygidium (tail) – fused segments forming the tail region.
Trilobite fossils are essential to paleontology, offering unique insights into Cambrian ecosystems, prehistoric marine life, and the evolution of early arthropods. Their remarkable preservation and diversity make them a favorite among fossil collectors and scientists studying Paleozoic marine environments.
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
