What Are Trilobites?

Trilobites are an extinct group of marine arthropods that thrived in ancient oceans for over 270 million years, from the Early Cambrian to the end of the Permian. Their segmented, exoskeletal bodies and wide geographic range make them some of the most iconic and well-known fossils in the world.

Phacops is a genus of trilobite from the order Phacopida, known for:

  • Large, bulbous compound eyes made of calcite
  • Well-defined segmentation and ridged thorax
  • Defensive enrolment behavior (some fossils are found curled in a ball)

These trilobites inhabited warm, shallow seas and were likely scavengers or bottom-feeders, using their keen vision to detect prey and predators alike. The Moroccan Phacops fossils are often found in Devonian limestone, offering exceptional three-dimensional preservation.

Why Choose This Fossil?

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.
