RARE Enrolled Brongniartella minor Trilobite Fossil

Caradoc Series, Ordovician Period – Coed Maes Newyddion, Eryri, Wales

This beautifully preserved, enrolled specimen of Brongniartella minor is a rare find from the Caradoc stage of the Ordovician, discovered at Coed Maes Newyddion in Eryri (Snowdonia), Wales. The fossil features a classic enrolled posture—a natural defensive position—providing a three-dimensional perspective of the trilobite’s exoskeleton.

This is a 100% genuine fossil, and the photo shows the actual specimen you will receive. Scale cube = 1cm. Please refer to the photograph for full measurements.

Geological & Stratigraphic Context:

  • Location: Coed Maes Newyddion, Eryri (Snowdonia), Wales
  • Geological Period: Ordovician
  • Stage: Caradoc (approx. 460 to 449 million years ago)
  • Depositional Environment:
  • Marine shelf environment
  • Fine-grained silty mudstones and greywackes
  • Suggests a relatively deep marine setting with quiet water deposition
  • Lithology: Typically found in dark grey, laminated mudstone beds

Taxonomic Classification:

  • Kingdom: Animalia
  • Phylum: Arthropoda
  • Class: Trilobita
  • Order: Phacopida

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.
