Phacops fossil trilobite in nodule (downingia) – ordovician, atlas mountains, morocco – genuine specimen with coa

Original price was: £60.00.Current price is: £48.00.

This is a Phacops fossil trilobite preserved in a natural nodule, dating back to the Ordovician period (~485-443 million years ago), discovered in the Atlas Mountains, Morocco. Phacops, a member of the Phacopidae family, is well known for its large, compound eyes and segmented exoskeleton, making it one of the most recognizable and sought-after trilobites among collectors.

Trilobites were ancient arthropods that thrived in Paleozoic seas, with their distinct body segments allowing them to roll into a protective ball when threatened. The natural nodule preservation of this specimen helps to highlight its fossilization process, offering an exceptional look at Ordovician marine life.

Fossils from the Atlas Mountains of Morocco are renowned for their fine preservation and scientific significance, making this trilobite an excellent addition to any collection.

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.
