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 a stunning and 100% genuine Trilobite Fossil from the Ordovician Period, expertly sourced from Morocco, a region globally recognised for its rich and diverse fossil beds.

Trilobites (meaning “three lobes”) are a group of extinct marine arthropods belonging to the class Trilobita. They are one of the earliest-known and most successful forms of complex life, with over 17,000 known species. Trilobites flourished in Earth’s oceans for more than 270 million years, first appearing in the Early Cambrian (~521 million years ago) and going extinct during the end-Permian mass extinction (~252 million years ago).

This fossil comes from the Ordovician Period (~485 to 443 million years ago), a time when marine life diversified significantly in what is known as the Great Ordovician Biodiversification Event (GOBE).

These fascinating creatures had segmented exoskeletons and a three-lobed body plan: a central axial lobe and two pleural lobes on either side, from which their name is derived. Trilobites were versatile and occupied a variety of ecological roles — from predators and scavengers to filter feeders. Some species even developed symbiotic relationships with bacteria!

Fossil Details:

  • Specimen: Trilobite Fossil

Ordovician Information

The Ordovician Period (485–443 million years ago) was a time of marine expansion and biodiversity growth, following the Cambrian Explosion. Warm, shallow seas covered much of the continents, supporting trilobites, brachiopods, corals, and the first true reefs. Jawless fish (early vertebrates) diversified, and the first sea scorpions (eurypterids) became dominant predators. On land, the first primitive plants (moss-like bryophytes) began colonizing damp environments. The climate was initially warm, but by the late Ordovician, a major ice age caused a drastic drop in sea levels, triggering the Ordovician-Silurian mass extinction, which wiped out nearly 85% of marine species. Despite this, the period laid the foundation for the rise of more complex ecosystems in the Silurian.
