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 genuine Trilobite fossil from the Ordovician Period, discovered in Morocco, one of the most famous fossil-rich regions on Earth. This specimen has been carefully chosen for its quality and represents one of nature’s earliest and most successful arthropods.

Trilobites (from the Greek meaning “three lobes”) are an extinct class of marine arthropods that first appeared over 521 million years ago during the Early Cambrian. They thrived for more than 270 million years until their final extinction in the Permian mass extinction around 252 million years ago.

By the time they appear in the fossil record, trilobites were already highly diversified and geographically widespread. Their easily fossilised exoskeletons and immense diversity—over 17,000 documented species—have made them invaluable to the fields of biostratigraphy, paleontology, evolutionary biology, and geology.

Trilobites were highly adaptive, occupying a wide range of ecological niches:

  • Seafloor crawlers – scavenging or predating
  • Filter feeders – processing sediment or plankton
  • Free swimmers – navigating ancient oceans Some even developed symbiotic relationships with sulfur-eating bacteria in anoxic environments, highlighting their ecological versatility.

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.
