Paralejurus Hamlagdadicus Trilobite
Trilobites are an extinct fossil group of marine arthropods belonging to the class Trilobita. They are recognized as one of the earliest arthropod lineages known from the fossil record. The first appearance of trilobites defines the start of the Atdabanian stage of the Early Cambrian period, dating to approximately 521 million years ago. These organisms inhabited ancient marine environments and are regarded as some of the earliest complex animals to evolve. Trilobites are a characteristic and important fossil group of the Paleozoic Era and disappeared long before the rise of dinosaurs.
A notable feature of trilobites is their mineralized exoskeleton, one of the earliest skeletal structures observed in animals. This rigid outer shell contributed to their high preservation potential, making trilobites common in the fossil record. The exoskeleton is divided longitudinally into three lobes—a central axial lobe bordered by two pleural lobes—a feature that gives trilobites their name.
The trilobite body follows a clearly defined structural plan consisting of three primary regions. The cephalon, or head region, contains compound eyes, feeding structures, and sensory organs such as antennae. Behind it lies the thorax, composed of a series of articulated segments that provide flexibility and movement, with the number of segments ranging from 2 to 61 depending on species. The posterior pygidium forms the tail region, where the segments are fused into a single, stable unit.
Due to their robust exoskeletons and extensive geological range, trilobites remain among the most abundant and well-documented fossil arthropods, playing a central role in the study of early animal evolution and Paleozoic marine ecosystems.
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 Morocco do a very professional job of unearthing and preserving these natural treasures; however, natural cracks are visible on the surface. These are part of the natural beauty of the fossil and are not considered defects.
