Trilobites (meaning ‘three lobes’) are a fossil group of extinct marine arachnomorph arthropods that form the class Trilobita. Trilobites form one of the earliest known groups of arthropods. The first appearance of trilobites in the fossil record defines the base of the Atdabanian stage of the Early Cambrian period (521 million years ago), and they flourished throughout the lower Paleozoic era before beginning a drawn-out decline to extinction when, during the Devonian, all trilobite orders except the Proetids died out. Trilobites disappeared in the mass extinction at the end of the Permian about 252 million years ago. The trilobites were among the most successful of all early animals, roaming the oceans for over 270 million years.

 

By the time trilobites first appeared in the fossil record, they were already highly diversified and geographically dispersed. Because trilobites had wide diversity and an easily fossilized exoskeleton, an extensive fossil record was left behind, with some 17,000 known species spanning Paleozoic time. The study of these fossils has facilitated important contributions to biostratigraphy, paleontology, evolutionary biology, and plate tectonics. Trilobites are often placed within the arthropod subphylum Schizoramia within the superclass Arachnomorpha (equivalent to the Arachnata), although several alternative taxonomies are found in the literature.

 

Trilobites had many lifestyles; some moved over the sea bed as predators, scavengers, or filter feeders, and some swam, feeding on plankton. Most lifestyles expected of modern marine arthropods are seen in trilobites, with the possible exception of parasitism (scientific debate continues). Some trilobites (particularly the family Olenidae) are even thought to have evolved a symbiotic relationship with sulfur-eating bacteria from which they derived food.

Description

This listing features an authentic Trilobite fossil dating back to the Ordovician Period (~485 to 443 million years ago), carefully excavated from fossil-rich formations in Morocco. Trilobites are among the most iconic and well-known fossils due to their distinctive three-lobed, segmented exoskeleton and incredible evolutionary history.

Trilobites (meaning “three lobes”) are an extinct group of marine arthropods forming the class Trilobita. These creatures thrived in ancient oceans and are considered one of the earliest and most successful animal groups, surviving for over 270 million years. First appearing in the Early Cambrian Period, they were already highly diversified by the time they appeared in the fossil record, highlighting their adaptability and ecological success.

During the Ordovician Period, trilobites reached a peak in diversity and abundance, with thousands of species adapted to various marine environments. Their hard, calcified exoskeletons fossilised readily, resulting in a rich fossil record that has greatly contributed to our understanding of prehistoric marine ecosystems.

Trilobites display a range of lifestyles – from bottom-dwelling scavengers and predators to free-swimming planktonic feeders. Some species even formed symbiotic relationships with bacteria. Their morphology, including their compound eyes, articulated segments, and variable spines, makes them a fascinating subject for fossil collectors and palaeontologists alike.

Devonian Information

The Devonian Period (419–359 million years ago), known as the "Age of Fishes," was a time of major evolutionary advances in both marine and terrestrial life. The oceans were dominated by armored placoderm fish, early sharks, and lobe-finned fish like Tiktaalik, which had features that helped vertebrates transition to land. Coral reefs flourished, and ammonites became more diverse. On land, the first forests appeared, with early trees like Archaeopteris, leading to a drop in atmospheric carbon dioxide and climate cooling. The first tetrapods (four-legged vertebrates) began evolving from fish, marking a critical step in the evolution of amphibians. The period ended with the Devonian extinction, likely caused by ocean anoxia and climate shifts, wiping out many marine species and reshaping ecosystems.
